Emily Gets Stronger

6PM 17.July Update
Emily is nearing the Yucatan this evening, and the eye is viewable on the Cancun radar. The eye was looking ragged earlier, but it looks like its reforming now.

Future track for a second landfall is still into Mexico, with southern Texas still inside the cone.


11AM 17.July Update

Emily is holding as a strong Category 4 storm, with a relatively small eye. Warnings are up for the Yucatan, and landfall will likely be overnight.

Since it is small it is likely to be weakened considerably by the yucatan so when it re-emerges in the Gulf it will still be a hurricane, but a much weaker one. And depending on how much the storm degrades, it may have a chance to become a major again for a second landfall most likely in Mexico near Tampico.



6PM Update
Hurricane Emily is now a high end Category 4 storm, 1 MPH shy away from Category 5 status. It is possible for it to become a Category 5 briefly still. It is still moving toward the Yucatan, and will likely be category 3 or 4 when it makes landfall along the eastern coast.



It will weaken some over land, and then emerge into the Bay of Camphece. A second landfall is Mexico beyond that is the most likely scenario. Folks up into southern texas will want to watch it as well.

99L is turning out to sea, leaving not much else currently in the tropics after Emily, which will be a welcome break.


Original Update
Hurricane Emily continues to Deepen in the Caribbean, now a category 4 storm, and has a chance at category 5, although if it does I doubt it will hold that extreme very long.




Emily is passing south of Jamaica, and the Caymans, but close enough that the Caymans will see strong winds, maybe as high as category 1 strength. Before it has moved on The Yucatan will have to deal with this directly later, and Hurricane watches will likely be up for parts of it later today.

Beyond that, and after it crosses the Yucatan. (Which should knock a lot of the intensity out of ti) it still looks like a Mexico hit or possibly Texas. The more likely of the two is into Mexico..

OK, visited the new Forecast Lounge forum, ready to make a forecasting fool out of myself! All as a way to provide a learning experience. Not anything happening over there yet so I hope you'll keep advertising the new forums.

Well I think this is the best of everything today - the opportunity to watch a strong storm develop, with no immediate landfall to put many folks in harm's way. Yesterday Emily had it out with that upper level TROF: she strapped on the pistols and announced, "Turn over the warm water, and no one gets hurt!"

I copy your questions to the new thread.....

Hey Clark--

Given that Emily has ramped up considerably and may intensify a bit more, is there any way that she might steer on a slightly more northerly heading. Nothing significant, just perhaps a subtle change from ~285 to perhaps, say, ~290 or 295. Isn't it possible for very strong storms to eat into ridges a bit? Just was thinking perhaps she might miss the Yucatan that way, and perhaps spin down a bit in the Gulf of Mexico. As it looks now, the Yucatan Peninsula is going to take some serious heat from this thing.

Thanks. Appreciative of your insight, as always.

If the storm does get to Texas coast area, there is 90 degree temperature water awaiting her. That could provide the energy for a last hurrah in strengthening if she weakens over a first landfall in the Yucatan.

Re: Emily Gets Stronger

Stronger storms do have a tendency to move a bit further north -- with the upper level flow -- than do weaker storms, but given the current flow pattern, there isn't a lot other than wobbling and the effects of Coriolis to help to move it off towards the north. It might move a little bit more WNW as it nears the Yucutan, but unless the western extent of the subtropical ridge erodes to some degree, it may well turn back moreso towards the west.

Re: Emily Gets Stronger

Thanks, Clark. I have just one more question. The five-day NHC track takes this thing well into central Mexcico, still as a tropical storm. Any chance any of that rain will reach extreme southern New Mexico/Arizona, or will the storm most likely track over Mexico south of the U.S. (including the Southwest)?

Re: Emily Gets Stronger

Looks to me like Emily's strengthening is done for now, and she maybe even weaken a little until later this aft/early evng, and then start to strengthen again. However the surface winds could still catch up before this happens, initially to go to 150-155 briefly, but then I am thinking they would fall back down to 145, 140, over the next three hours, then strengthening again.

Eye is very impressive. It has grown quite a bit - what are the implications of this, if any?

Not surprising considering Discussion 23 "...with 700 mb flight-level
winds as high as 148 kt. This would normally support surface winds
of 130-135 kt."

But look at the cloud tops on the west side the last couple sat photos - not as cold now. Although to Emily's credit she is staying compact.

notice eye

has gotten larger, and is perfect now. I suspect Emily will be a cat 5 storm. Is there any chance that she could begin a more northward turn?....if this storm slips through the Yucatan, and hits NO...it'll be a disaster of monumental proportions.

Anyone on the Yucatan in anything less than a conrete block building....will be in serious danger of losing their lives....when they get to 150+...we all know it's now a question of survival.

HankFrank...watchya think?......could the ridge weaken?...could Emily head more north...?....I wonder....because she "appears" to edging ever so more north than west through the hours....

It doesn't have to though... the weakening phase is a good thing, and then perhaps conditions will change and not allow it to restrengthen.... Seems like there's at least a chance to me, rather than purely intensifying...

Merida looks to be the largest city in the Yucatan, with some fancy hotels, freeways, an airport - and all on the west side of the Yucatan, but not on the coast. Looks very, very safe. I don't think you need to worry any more.

Re: special statement

Well would you look at that? The Jamaican land mass didn't affect her that much, the core got smaller, and son of a gun if a band of colder cloud tops wrapping quickly around the western side isn't filling in the circular shape nicely. I thought something was happening a couple of hours ago - looking at the water vapor it seemed like the outflow hit a bit of a wall - at around 82W on a N-S line but I guess that wasn't anything, and I'm just not that good at reading the maps yet. Guess that warm water she's been going over is really helping things along.

I had always thought she'd go to a CAT 5 today, but I had envisioned the big strengthening happening later this aft and into this evng.

Not looking so good for Cozumel and Cancun, but the roller coaster ride of intensity could mean Emily won't be this powerful at landfall. Looks like the minimum will be a strong CAT 3 though.

Sounds to me as if you have quite an issue with the people that post here. Please remember - we are all REAL human beings with feelings. I for one do not appreciate the fact that my concern for others ends when a storm leaves the borders of FL. I live in Central FL and went through the storms and recovery last year. This makes me a bit gun-shy and a bit more concerned as I see, or hear, possibilities that storms may affect me. IN NO WAY does that make storms that do not appear to affect me a non-issue. I have friends that like all around the GOM basin, including contacts from other organizations that live in other countries. I am very concerned aboput them as well. My prayers are as much with them as they are for my own town when we appear to be in the cross hairs.

True many of us do not post as much when a storm turns elsewhere, but that has much more to do with the fear for our own safety subsiding and allowing us the ability to watch and learn from those who are much more knowledgeable about these storms then we are.

I realize that this comment would be better directed to PM but since you are unregistered I could not do that.

Thanks again to everyone here (and that would be just about all of you) who know more about these incredible storms than I do. You willingness to provide information to me ad everyone else has helped me develop a true healthy respect for these storms.

I was wondering about this as Dennis made landfall last weekend, and now it's coming up again with Emily:

What is the average time in between EWRC's? And how long after completion of an EWRC does the intensity peak before the next replacement cycle begins?

Nope. Earlier in this post or the previous one someone asked and the reply was that the earliest recorded Cat 5 was Allen in 1980 who became a Cat 5 on Aug 5th. And came ashore just south of the Mexico- US border .... almost exactly where Emily is supposed to be heading...

To me this is more interesting than if a hurricane was headed for the US; one I'm much more relaxed, now that I don't have to worry about someone I love being in a risky weather situation. Two because how many storms to we get to observe that can go to CAT 5 status? It is just facinating to watch. Even the last two sat visuals (17:45 and 18:15 UTC) are facinating; look at the perfectly round donut shape of the tight core of clouds around the eye.

Thanks, Bill!

We have been talking alot about eyewalls on this board lately, but I didn't remember seeing anything specifically about timing of the replacement cycle and when peak intensity occurs in the cycle...

But I did manage to go back and find one of Clark's explanations from several months ago:

Quote:

What is still unknown is the exact predictability of when one is going to occur as well as how fast they will occur and how far they will reach towards the center before resulting in the collapse of the original eyewall.




So I guess the answer is...

I'm just going by what happened with two previous big hurricanes - Gilbert and Allen. There were tornadoes etc here. It's pretty difficult for a hurricane to actually hit Austin - we're not on the coast. But Carla in 1961 was still a Cat 1 when she got here.

And the Rio Grande Vallley (Brownsville on up the river, Larado etc) could possibly get the bad side of Emily depending on how far N/S she is on landfall.

I'm not gloom and doomin south and central Texas, just sayin that if Emily makes landfall in Mexico, parts of Texas could be adversely affected.

Re: notice eye

Someone mentioned earlier about the lack of posts on the board, or lack of interest for Emily... I don't agree that there is any lack of interest... I am following Em just as diligently as I did Dennis... only issue or rather non issue with Emily is that is has been so well behaved and basically right on track, with the exception of its tremendous intensification process, which is absolutely amazing to watch... I think things will pick up quite a bit on the board once it enters the GOM... and yes, there is more interest all in all if there appears it could impact the US... I think a threat to Florida generates the most interest, following by a central or east central GOM threat, but that is only natural of course... Emily is an amazing system... I just can't imagine the stress level that would preclude it if it were to threaten the US as a strong 4 or heavens forbid a 5... One only has to wonder what's in store for the all of us for rest of the season... and how likely some poor city is going to get blasted with a major hurricane later on.. It almost seems inevitable at the moment...

Yes but that's going on the recon from just after noon today CDT, right? We should be seeing the results of another recon by around dinnertime?




I would assume that they are pretty much in and out all the time.




No, I think they have a schedule and I think it is every six hours. I am not sure if I am understanding it correctly but it looks like right now it takes them about five hours just to get there, after taking off.

I was reading about what they do with those C-130s. They take the entire center of the plane where you'd normally have cargo or people, and turn it into one huge gas tank.

Re: notice eye

5:00 is up - looks like they will keep her at a 4, although they did say she could fluctuate between a 4 and 5

"SOME FLUCTUATIONS IN STRENGTH ARE EXPECTED
DURING THE NEXT 24 HOURS...AND EMILY COULD BECOME A CATEGORY FIVE
HURRICANE AT TIMES. "

I guess they don't call it a 5 unless the hurricane stays up there a bit? I mean, nhc won't make updates every hours, minute, (insert fluctuating time period here) saying, "she's a 4, now she's a 5, back to 4, up to 5" over and over, would they?

I don't know if Central Texas may get much out of Emily, maybe some rain but I don't think it would....but anyone else know if Emily is supposed to hit Central Florida or at least bands to hit Central Texas.

I'm just going by what happened with two previous big hurricanes - Gilbert and Allen. There were tornadoes etc here. It's pretty difficult for a hurricane to actually hit Austin - we're not on the coast. But Carla in 1961 was still a Cat 1 when she got here.

And the Rio Grande Vallley (Brownsville on up the river, Larado etc) could possibly get the bad side of Emily depending on how far N/S she is on landfall.

I'm not gloom and doomin south and central Texas, just sayin that if Emily makes landfall in Mexico, parts of Texas could be adversely affected




Ditto to what Shana said... also, think about what Dennis has done to the Ohio Valley, Atlanta, and other points well inland of the coast.

Of course, it all depends on where she makes landfall, which direction she is moving, how big she is at the time, and any other weather features that may be in place -- but sure, Central Texas could see parts of Emily....

With this storm, all afternoon each satellite frame just looks better than the next one (better in the sense the storm looks stronger and balanced), even when you think it can't get more perfect. What an afternoon! We won't get to see anything like this again in a long time.

Looks like it may finally start to take that more northerly path, and may just skim the edge of the Yucatan instead of a direct hit, but all afternoon it's been going in a straight line, no jogs, nothing, just smooth sailing for Emily. Just thought it seemed to jog a little north...but maybe it will remain a jog.

As the storm pressure drops the steering currents change for the system. Here is an analysis of the steering currents at the current pressure and you may be correct.

I don't see how it could get much below 920, 915. It passed over the warmest water today and is running out of ocean real estate before cooler water.

Answering my own post...a little sick, I guess.

I realized maybe there is a lot of analysis for NHC to do with the recon data, and why jump the gun before doing a complete analysis. 11pm advisory is plenty of time to upgrade to Cat 5, and maybe even wait until morning recon if it is borderline.

EDIT - I was just thinking also - if deepening continues at this same rate, which is certainly possible, it could be down to 920mb by next recon.

Here's an interesting tidbit... Gilbert reached 888mb at 19.7N 83.8W -- just south of the Isle of Youth.

I don't know if there's any way to find out what the conditions surrounding Gilbert were at that time, and how they might differ from the conditions around Emily -- although most likely he wasn't headed into cooler waters...

I don't have a handle on how often the ocean temps change but I think it is something to look at daily, so what is warm one day may not be the next, also the depth of the warm water is a factor as well.

I think he means: 150kt flight level winds = 150mph surface level winds. That sounds about right based on the NWS eyewall profile study:
http://www.nhc.noaa.gov/aboutwindprofile.shtml - pay particular attention to Figure 1. Changing kt to mph is equivlent of 0.86 flightlevel winds to surface winds, so it would show as slightly weaker than it really "is" (is is appoximate - check the two sample profiles to understand why).

Thanks. That's a great link, too.
It's just a rough, fast way to determine what the Surface Winds are.
Each storm is a bit different...as there are no Perfect Storms.
150kts x 1.15=172.5mph x 0.86=148.35mph.

So the 150kt Flt Lvl Wind, is roughly 150mph at the surface.

From Steve Gregory's wunderground blog:

"Another RECON report shows the pressure is up 2mb, but there are times that the dropsonbde 'misses' the dead center of the storm.
But in any case, pressure seems to have stabilized, and the last few stepped IR images seem to be showing a weakning to the convection on the sSSW side of the 10NM wide eyewall, and we may be starting an eyewall replacement cycle.
The temp difference is between the inside and outside of the eye is as high as I've ever seen, 16degC. This implies an extyremely tight, very healthy circulation. So the weakening of convection on the south side of the eye wall almost certainly is the first signs of an eye wall cycle replacement.

With very warm, high heat content water ahead, and no change seen to impact the outflow a top the hurricane -- Emily will probably resume some further intensification, reaching CAT 5 status during the next 18 hrs.

+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
JULY 16 - 7:55PM CDT

Hurricane Emily has now broken the all-time record for strongest storm so early in the season, with a central pressure of 929mb."

Re: RECON Update

Also I figured out why the surface winds didn't change from 155mph from the older recon (from six hours previous).

Even though max flt lvl winds were 141kt in section F. (I think also this was from the NW quad), the notes in section P. showed max of 151kt in NE quad. That is the number they went by in the earlier recon, not the 141kt.

So change from 151 to 149 max flt lvl winds is not significant.

And even though the pressure dropped from 937 to 929 it still wasn't quite low as they look for to determine a Cat 5 (920).

I think I looked at it all day, and it looked so perfect I could not believe it was not yet a Cat 5. Still looks so awesome on the sat images.

Try a factor of 1.04 for computing the surface winds from the max flt lvl winds. Doesn't look like it would make such a difference, however it makes a little bit of difference. 149 * 1.04 = 155. However this factor doesn't always stay the same.

You can see the eye getting a little smaller very clearly on the water vapor loop.

It was 12nm this aft I believe, down to 10nm at the last recon? Not 100% sure on those numbers.

Well it if is still 10nm it may have a little way to go, maybe down to 8nm, before an ERC? But that seems to be the speculation in the air all 'round anyway.

From Steve Gregory...

The RECON so far found a max wind of 149kts, but it is likely, that 160kt max flight level winds
are occurring. Typically, 920mb is the threshold / benchmark standard, besides wind data, used
in the Atlantic basin to Categorize a storm as having CAT 5 intensity -- the highest Category.

http://www.wunderground.com/blog/SteveGregory/show.html

It is confusing...SS is a wind scale, so I was with you, waiting for the upgrade, until I read this...

You are correct in that the intensity scale (Category) is based on wind. But, one minor correction: the conversion factor from knots to mph is 1.15, i.e., 135kts times 1.15 equals 155.25mph.

Intensity a function of both pressure and wind speed - pressure is officially 930. Also deepening has stopped, evening has come, and an ERC might be starting. It is more probable that intensity will now fluctuate downward until after the reorg that will come after an ERC (if one occurs). That might be happening tomorrow when the storm will be going over warm waters again and have the heat from the sun. More likely to see a Cat 5 tomorrow afternoon or evening rather than tonight.

One thing though, it seems that in these warm tropical waters it is possible to have just as much strengthening in the nighttime as in the daytime. So maybe time of day is not such a factor at this type of location.

Actually, I cheated and used a table.... How about this conversion factor (that came up when I looked for the conversion table I used):
1 knots = 1.15077945 mph

That's a lot of significant figures!!! So, that would mean... 155.35522575

Seriously though, I think the 1.15 is plenty of sig figs... I can't imagine a conversion factor having 9!

Thanks for the correction. I always seem to get busted when I'm being lazy.... I guess that should tell me something!

Re: Update from Grand Cayman

From Discussion 25:

"EMILY HAS REMAINED ESSENTIALLY STEADY-STATE DURING THE PAST FEW HOURS AS A HIGH-END CATEGORY FOUR HURRICANE. HOWEVER... AN AIRCRAFT RECON FIX AT 2340Z DID INDICATE THE CENTRAL PRESSURE HAD FALLEN 8 MB SINCE 18Z TO 929 MB... AND A MORE RECENT FIX MEASURED 931 MB.
THE MAXIMUM 700 MB FLIGHT LEVEL WIND IN THE NORTHEASTERN QUADRANT WAS 149 KT... WHICH SUPPORTS MAINTAINING THE INTENSITY AT 135 KT. DVORAK T-NUMBERS WERE 6.5 FROM SAB AND AFWA AND 7.0 FROM TAFB... SO THERE IS NOT MUCH BASIS ON WHICH TO UPGRADE TO A CATEGORY FIVE AT THIS TIME. SINCE BOTH THE OCEANIC AND ATMOSPHERIC ENVIRONMENTS IN THE WESTERN CARIBBEAN APPEAR TO POSE NOTHING OBVIOUS TO WEAKEN EMILY... INTERNAL STRUCTURAL CHANGES WILL LIKELY DETERMINE INTENSITY CHANGES BEFORE EMILY PASSED OVER OR NEAR THE COAST OF THE YUCATAN PENINSULA."

Makes a lot of sense. Also looks like NHC knew they'd have to provide detailed logic as to why not upgrade to a Cat 5.

Also notice they are now mentioning the possibility Emily may not hit Yucatan peninsula at all.

Re: Recon

Just got this info from a friend.

Neil Frank from KHOU said

Chance for Emily to take a right turn. Key to where she will go is the florida high. Low over Texas is anticipated to weaken & Florida high moves. But if high stalls and doesn't move to the west, emily will take a more northerly track. Wednesday's local forecast is a little uncertain. There is an outside chance the storm could come our way

Saw this earlier http://www.wunderground.com/tropical/tracking/at200505_strike.html, that put LA/MS in the 5% possibility area. Still really slim, but you never know. Probably not, though...Emily seems to go where she wants to, and there is something to the west that she wants (refried beans?)

oops - they changed it ... now just up into LA! I swear it was different earlier!!

emily etc

as far as all the discussion over what defines a cat 5 and whether emily would make the cut... the fact that the pressure has thus far bottomed at 929 and not gotten to 920 means nothing really... a storm with a higher pressure can have cat 5 winds, it's just a function of how tight the inner core gradient is. in this case it's very tight, so a slightly higher than traditional pressure is producing near cat 5. the standard for flight level to surface windspeed reduction is 90%. 150kt X .9 =135kt or 155mph. this doesn't always work out and they call it as best they can based on what the dropsondes and recon onboard instruments say... and adjust by how good the satelite presentation is. not a standard formula to it, really... forecaster interpretation comes into play beyond that. all in all they do pretty good, though.
anyhow... expected track mostly unchanged. probably going to get the yucatan higher than i was talking last night, and the mexican mainland perhaps a little south (that left bank under the continental ridge has become more pronounced in the models). on the other hand i can see some weaknesses above the 500mb level (weak upper lows linked from the gulf to yucatan) that may reshuffle the deck. forecast track still looks pretty close to reality, though.
i'm not certain yet, but it looks like 99L is breaking through the upper trough. the convective area from this afternoon looked like the shear had won, and was left behind by the low-level cyclonic kink... but more developed after dark closer to 23/54.. and this is moving wnw. if enough has made it through, the main influence will on this system will change to the ridging off the east coast and the northerly flow west of the upper trough... a less mitigating factor as time progresses. i'd say this thing is up to 50-50 now on spinning up. the models don't have it drawn up right, but the piece that got through ought to be enough. be wary of this thing on the east coast if it starts developing.
SAL more influential behind the 99L system and is squelching subsequent waves, even though their signature is decent. the east atlantic will have more trouble generating a system for now (until the larger august waves start coming off), but these can still fester further to the west. fortunately the globals aren't latching onto anything.

To correct a previous post... Hurricane Allen made landfall NORTH of the US-Mexico border... close Laguna Vista and Port Mansfield, TX. Happened Aug 10 1980.
By the time Allen moved ashore, it's maximum sustained winds were 100kts.
It's greatest impact was in the desolate area of Northern Cameron county and Willacy county.
Allen's path was north of Jamaica ... and north of the Yucatan peninsula.

Neil Frank is the only local guy I trust when it comes to hurricanes near Houston.

With that said, I have a lot of confidence in the NHC and how they're tracking storms this year. And their track is pulling more and more to the south, not to the north -- that's good enough for me... (for now)

Anytime one of these things gets anywhere near the Yucatan, our local mets get all charged up about it... (not so long ago, one met, Frank Billingsley, was even seen drawing an "xtrap"-type line between Dennis and Houston while all the models clearly showed Dennis moving toward FL/AL... )


If Neil Frank is still talking about it on Monday, then I'll worry...

AT 0324Z...THE AIR FORCE RESERVE UNIT HURRICANE HUNTER AIRCRAFT REPORTED FLIGHT-LEVEL WINDS OF 153 KT.

This is probably in response to a model showing a northward trend.
New Iberia, LA had been removed from the 11 PM Strike Probs. last night.
Port Arthur, TX gained 1 point in the 5 AM Probs.

Also noted, again probably due to model trends doing their 6 hour swing, were drops in the Total Probability for:

...and what a good morning it is! Emily stayed way south, further south than forcasted. Highest sustained winds 35MPH experienced around 0300EST. Currently winds around 25 out of the East with light rain.
Electricity stayed on all night. Curfew still in place. Understand waves have come across Pedro Bluff inland 1/2 mile. Waiting for curfew to be lifted before being able to assess.

Another day, another chance at Cat 5

Good morning everyone!

Well in a way it is a shame that Emily didn't get stronger because isn't it possible that could have changed the steering patterns a bit, and now it looks with the continued west movement, like a direct hit on Cozumel and Cancun. Last night I wondered about that but was too tired to make one more post. I had flhurricane fatigue.

And I realized why the warnings are going along the top of the peninsula as well - because of all the winds they will get from the N as Emily goes inland, if she lands close to the N tip. Weird to think of N winds as being a problem because they are onshore. Also I see how different the strengths are in the different quadrants, and that the N of the storm is so much stronger than the southern part. So it is really sad to see that the entire N part of the penisula is going to get hammered, especially the beautiful tourist area.

Well the first thing I did was look at the satellite to try to figure out what I could on my own, then read the advisories and discussions. I was surprised to see Emily looking so strong, stronger than I expected to see this morning, and again just so perfectly round. I guess it is "here we go again" because looking so good (except for the outflow to the S), and having warm water, it is possible she might still intensify. Still with all the land to the south and west, how can conditions be quite as good today as they were yesterday.

One thing I was confused about was if an ERC did take place, and it seems that it did, since the eye changed diameter and went eliptical before I went to sleep last night, then why is the resulting new eyewall only 10nm? I don't know very much about this but thought the resulting eyewall would be larger.

The eye doesn't look nearly as good as yesterday so I am assuming that the storm still has some reorg left to do to finish up the ERC cycle? Since pressure started dropping again I assume Emily is reorganizing now and we can expect to see her looking *better* on into the afternoon.

Well this is interesting because the population is high. Every time a hurricane approaches a major city here it is like a nightmare. They don't have anywhere to go on Taiwan. So what do they do over there with a Cat 5 direct hit? Maybe there is something we could learn from Taiwan.

Re: Emily Gets Stronger

OK. Taking into account the latest recon, and looking at the sat images, at first I thought what a mess, Emily is falling apart. Then I looked at the visual, and it seems to me that the tight inner core, now smaller, is still looking organized and good. Before, when Emily reorganized, she left a lot of the stuff on the edges behind, and the inner core emerged and grew into a nice round clean storm. I think this is what is happening now. However it is looking like she won't get more than 12 more hours to reorganize with the higher speed. So it will be interesting to see how soon it takes her to start getting her act together again and how fast she may intensify before landfall.

It is interesting to try to understand what is happening, but of course I have no technical background in meteorology so it will be helpful if any of the moderators can provide the technical detail about what is happening now and what we can expect to see in the next 12 hours.

42057 is adrift and from the data it looks like Emily went by her last night. No impressive readings; the SW side of the storm wasn't very strong at that time.

42056 is at 20N 85W. By the time Emily gets to 85W she is probably not going to be any further north than 19.3N.

So how many miles in 0.7 lat? I don't think the inner core of strong winds will make it close enough to the buoy to see any readings like the ones of the Dauphin Island buoy last year before IVAN hit.

emily working out kinks, 99L hanging in there

emily's cloud pattern got jarbled later this morning. recon says it isn't an erc... probably some subsidence intake near the end of the last erc overnight is my reckoning. emily was approaching the detritus of a weak upper low the other day, so maybe the remnant vorticity at the upper levels mixed up the outflow pattern or something. speculation.. either way the pressure is up to 946 which is typically a 3/4 borderline. the winds supported are a little higher according to recon.. i'd expect this to dip back down.
path today should take emily in a little south of cozumel around midnight, back offshore near merida/progreso late tomorrow. spindpwn/spinup will probably resemble dennis crossing cuba about a week ago. think the left track bend prior to second landfall is slightly overdone, and that the storm will come in closer to the tx/mex border.. but not by much. cameron/willacy counties might get a few peripheral gales and a t.s. warning out of it... pretty sure it doesn't come close enough for significant damage, though. think second landfall intensity will be 3/4 borderline area.
haven't given up on 99L. the low level vorticity is moving under the upper trough axis right now.. two maxes i can see. the southern max is weaker and moving mostly w near 23/58.. spotty convection out in front. the more formidable max is near 28/57 and moving wnw, with convection closer by. most of the convection associated with the wave is being forced near the exit region on the ne flank of that upper trough max near 20/60. as the wave axis passes the upper trough axis, it should start to generate a more conducive convective pattern for organization than the sheared pattern it's had for three days. if none of this happens in the next 36 hrs, or so... the whole thing is probably gone. if enough made it through the upper trough, though... it'll do some interesting things.
SAL seems to have killed the wave action for now in the eastern atlantic. they may act up as they near the caribbean.. globals continue to forecast a wave-friendly environment for whatever regenerates when it gets back across... nothing showing right now to speak of. gfs is showing distant interest in a wave that comes off africa in about 9 days... tracking it as a discrete feature through day 16. nao has been mostly positive and soi as well.. oscillations in both can lead to more energetic mid-latitude breakaways and backing at low-latitudes... until they twitch again, it's up to the more energetic of the african waves to trigger disturbances. there is weak mjo action at play as well, so some time in august we may see a flash of that as well.

Re: Emily Gets Stronger

coastal flood watch has been issued for the central gulfcoast




Emily will generate waves of a very long period
between crests... which will travel northward across the Gulf and
result in heavy surf and possible coastal flooding along area
beaches late Monday and Monday night. The large waves could also
result in erosion of beaches... including those areas previously
damaged by Hurricane Dennis last weekend... and tropical storms
Arlene and Cindy earlier this Summer.

The west end of Dauphin Island Alabama will be particularly
vulnerable to coastal flooding... as similar events have produced
heavy surf and washover there several times over the past couple
of years. Hurricane Mitch... while over the western Caribbean
in October of 1998 as a very strong hurricane... produced long period
swell which propagated northward across the Gulf... inundating parts
of the western end of Dauphin Island. Along the Florida Panhandle
coastline... heavy surf should be expected... but there is no
precedent for extensive coastal flooding with this type of event.
However... with the beaches severely eroded as a result of all the
recent tropical activity... some minor coastal flooding could be
possible late Monday and Monday night.




2 PM EDT position...19.0 N... 84.4 W. Movement
toward...west-northwest near 20 mph. Maximum sustained
winds...145 mph. Minimum central pressure... 948 mb.

The next advisory will be issued by the National
Hurricane Center at 5 PM EDT

OK so Emily's eye will be about 40m S of the buoy when it crosses around 85W, and it will be more than twice that distance away by the time it comes W of the buoy. Based on the most recent supplemental recon it is likely the buoy will only see at most 70kt winds, just over the threshold of hurricane force, so I am guessing you wouldn't expect to see wave heights over 30ft, maybe 35ft, and that only because it is the NE quad.

Re: Emily Gets Stronger

Mike, I think it was deleted because moving it would've killed much of the rest of the thread.

I saw the article about that in the Orlando newspaper yesterday; it's better suited for the new Predictions forum, IMO. Truth be told, I'm not sure exactly what they are going to try to be getting out of it...real scientists are not going to place their money on a landfall pool for any tropical cyclone; there's simply too much at stake. Thus, it is going to be the semi-pros, the hobbiests, and the general public that tries to make some money off of the market. That will reduce the pools to wild guesses, the NHC forecast, model guidance forecasts, or media outlet forecasts...and I'm not sure what is to be gained there. If it is an attempt to see which forecast performs best, that is already done in a formal basis by the NHC each season. It's not like the stock market, where the goal is money; it is real life, with real lives at stake, and I'm not sure I see how having (essentially) a landfall pool is going to help matters. Perhaps something similar without using money can be adapted to a forecast module to teach students/the general public/others how to better forecast these storms, but this doesn't appear to do that.

Just my two cents, however.

Back home and checking the sat images, Emily is looking a lot *better* (3:15p CDT) on the water vapor loop, even with the small scraggly eye. She certainly is the comeback kid. Looks like she is ready to get her act back together, only she really doesn't have a whole lot of time. But I bet she looks even *better* six hours from how, and the next recon will show a pressure drop.

Watch out Texas



There have been some changes in the track model guidance...likely
due to better model analyses of the mid-latitude trough over the
northwestern United States and its subsequent impact on the
southern U.S. Ridge. Large-scale models are now calling for more
of a weakness in the ridge over the western Gulf Coast. This
causes the track guidance to forecast less of a westward turn while
Emily is over the Gulf of Mexico..

Just doing a little checking, those were Nautical miles. Using the distance between the Equator and North Pole = 6222 miles (statute) and dividing by 90 (90º latitude between them) yields 69 statute miles per degree of latitude. So, 0.7º would = 48.3 statute miles.

Wow. Brings back some memories that I tried to keep from coming out. Rode out two typhoons mid-island near Taichung in 1968 and flew evac. to Itazuki Japan for another. Remember riding a motorcycle to Sun Moon Lake and the road washed out with about 2.0 ft left on the side of the mountain. Got the bike across but no one else could. Happened just after I stopped inside a tunnel to fix a problem. Also, in the late 80s took a train from Shanghai on the mainland south which took over 14 hours. Found out a typhoon had destroyed the track in front of us and the Chinese Army was fixing it as we went along. Got into the city (cant remember the name but it is famous for West Lake) and it was like a Hollywood movie. Thousands of Chinese peasants sitting on the ground in the rain around the train station. Had to walk to the hotel and it was the only one with a generator and air conditioning. Trees were down, buildings were destroyed and people were living in the streets.

Cool. I was looking for the Cuba radar too but couldn't find it.

Dumb moment: Actually I did see the link to the Cancun radar...but you had said Cozumel, and when I saw the word Cancun for some reason I kept thinking it was Cayman and that radar wouldn't show anything right now. Too many C words huh.

I just read in the last hour somewhere about the second eyewall but can't remember where I read it, but yes you can definitely see it. Well it'll be a race to see if Emily can reorg any more before hitting shore. Even if not, it appears that the eyewall is still going to pack a pretty hard punch.

Just checked on buoy 42056 and sure enough wave height 32 ft and wind just under 60kt gusting to over 70kt. That was about as intense as I thought it was going to be, but maybe not since wind isn't coming out of the SE yet.

The Weather Channel has Mike Bettis in the Cancun/ Cozumel area doing updates, and live reports.
Either CNN or TWC reported late this afternoon, that the Last Flight out of the airports had left.
They estimated 130,000 tourists left in the area. I believe I heard that 67,000 or so were from the U.S.

They have moved the coastal plain area people to higher ground and/ or evacuation shelters.

Re: Emily Gets Stronger

The eye on the Cancun radar is clearly showing evidence of an eyewall replacement cycle, just like what was hinted at during the 5pm discussion. Within the next few hours, we'll see the rest of that inner eyewall collapse and an eye of 25-30mi in diameter consolidate in its place. Once again, it looks like another landmass might just be spared the worst of a storm due to an eyewall replacement cycle right before land...we'll have to see how much this one takes out of the storm, but throwing it into a state of reconsolidation right as it is about to hit land should keep some of the intensity in check, both before it hits land and in the hours across/just past land tomorrow.

Given a little time over water Tuesday, the storm could well deepen once again in the warmest waters in the entire basin...though I'm not going to buy the deepening to 910-920mb that our MM5 is calling for. Outside shot at taking a run at its former intensity, but I don't think it'll have enough time. The further north it goes, the longer it sits over those waters...but also the more it interacts with the midlatitudes and the more likely it gets strong enough to have an eyewall replacement cycle occur near landfall. Further south keeps it over water a shorter period of time, which is both good and bad. Only time will tell as to what happens, and for now I see no reason to go against the NHC path, both in terms of intensity and track.

Re: Emily Gets Stronger

Well this may be going out on a limb but ever since awhile ago when the outflow started looking so good, it seems like Emily was on a roll again. Now it seems like this is the case, because the eyewall replacement which has been trying to happen for the longest time is completing, and I think there are enough hours left for the conditions to improve in the core. I am thinking a very very small but powerful center will result before landfall, but everywhere else, not much punch. Now it looks like one of the recon flights is targeted to arrive after the others and to hang around in the area for some hours, so perhaps there will be up-to-date readings of the environment around the core right up until landfall around 11 tonight.

Well I'm gonna post this and go track down the 8pm update!

Ok looking at the various floaters at the nhc, it appears that Emily is falling apart *and* trying to make a hard right turn at the same time. What I think I'm seeing is the effect that land has on the hurricane, because it seriously looks like some sort of wall is just ahead of emily and the storm really doesn't want to go that way. I wonder if it could weaken the storm?

I'll look again in a couple hours to see if it's more than a wobble or optical effect. But I wonder if something ... odd... is taking place? Any thoughts?

Re: Emily Gets Stronger

They will probably be just fine where they are and will probably just see some gusty wind and some rain.

The eye will pass considerably to the north of them, it will have been over land for quite some time, the intense part of the storm is extremely small, and that intensity doesn't last very far inland.

So all they will see is a lot of rain and some gusts, maybe up to 25mph, occasionally. In other words, they could be on any floor, they could go outside in the rain, they will be fine.

Re: Emily Gets Stronger

Whoa....the eye is projected to pass very near Merida, and given the forward speed of the storm and the relatively flat terrain of the Yucutan, it'll likely keep hurricane intensity throughout. Winds to hurricane force can be expected in the region -- maybe a little less if it passes just east of there -- with gusts higher. The main threat will be rain and flooding, yes, but wind damage is likely in the region too. I don't want to raise an alarm, but they are very much in the projected path. Being a story or so up is fine to keep from feeling any potential flooding impacts; being higher up isn't due to the higher winds aloft.

To take on some other questions...

* There is no TD behind Emily right now. Anything near Emily is an artifact of the storm itself, while there is nothing else of interest until you get east of the Lesser Antilles. The convection you see there is currently rather disorganized and part of the interaction between the old 99L and an upper-level low. Not likely for development at this time in the next few days due to the upper low and dry air in the region. Upper lows can work their way down to the surface and spin up something, but I don't see it really happening here...and even if it does, it'd take several days.

* The overall satellite appearance on Emily has improved from earlier, but it is nowhere near the intensity that it was just a day ago. Even a 20mph drop in winds -- I suspect it may be a little more than that before landfall -- is an exponential drop in damage. Given the small size of the storm, that's a lot. I suspect the storm is feeling the influences of the upper low over the Bay of Campeche, both in the northward jog over the past couple hours and a slightly sheared appearance. Wobbles can be expected to landfall, given the reorganization of the storm, but a maybe slightly further north motion than we've been seeing can be expected in the short-term (~6-12hr), evening back out more towards the west thereafter.

* Why have people not left? Well, while there are a number of resorts through the region, there are a lot of people in that region who simply cannot leave. Where else would they go? It's just like in the United States, where people go to shelters or to safe houses...when you are in an isolated region with your entire family with you, where are you going to go? Most people there have taken precautions and should come through the storm relatively okay. It's nothing they want to deal with, of course, but their preparations and lead time are just the same that we get.

* Wave action is going to be very high near where the storm makes landfall, despite the dropoff in intensity. The wave action has been building up with the storm for many days now; the fast translation speed of the storm has aided in this, allowing the waves to build and build and build. The jog northward and overall small size of the storm may have helped to contain these effects somewhat, but they will still be felt. The Weather Channel graphics earlier today were showing a broad 1-3' area of water rise...with knowledge of where the center is going to make landfall (give or take) now, I would ramp that up to over 10' near the landfall point, dropping off from there.

Re: Emily Gets Stronger

Thanks Clark.May I ask you about what you think the damage to Playa Del Carmen will be?Most everything there is right on the beach or very close.I know I am asking alot ,but there are people here with me that would really like to know if they will have a town to go back to.How deep will the water be say,3 blocks from the ocean there.Will Cozumel be enough to help with the storm surge in Playa.Please just give me your opinon on the damage to Playa Del Carmen.Thank you very much.

Re: Emily Gets Stronger

I did get carried away, didn't I!

Well a very nice line of thunderstorms is passing through. I'm up on the leading edge in a southern suburb of Mpls but the entire nasty thing is starting to bow out further down south, and we just started getting a lot of lightning.

Typical MN fun after we get an unusually warm day. Temps will be a lot lower tomorrow.

Thanks for your view, Clark. I did think Merida was in a direct path, and was confused as to what would take the force down with the lack of any elevation. I know it is not that close to the coast, but did not think there was enough real estate in between landfall and Merida to take it down much.

I've checked both the WV and IR imagery. I appears to me that the eye may be displaced to the NW. I see a tight curl in the last hour NW of where the ERC was taking place.
I'm using http://www.ghcc.msfc.nasa.gov/goes




I saw that on the 00:15 water vapor and thought, no. Then I saw the 00:45 and 01:15 and was !what! I have no understanding of what's going on now, except that Emily's last bid to reorganize might have failed because she is so close to land.

Looks like the eye may come ashore around Tancah. If so, I really doubt if Cancun will see much of anything as far as wind. Forgot for the moment they'd still get storm surge.


That is only about 10 miles north of Tulum,I can not see it hitting that far south.Now the eye in not looking great,I give up.For 3 years I was up and down this coast,I do know it well.It is one of the coolest places on earth.




Actually I just heard TWC say Tulim...which I had considered but thought a little too far south.

Also they just said pressure up to 955...so they must have access to more of the recon data we haven't seen yet, and the storm is still weakening.

On the current track from the NHC Merida can expect 9 hours of tropical storm force winds starting 7-18-05 05edt peaking at 54 mph at 7-18-05 08edt. If you need any close up maps just let me know. Hurrevac will be up all night long .

11 PM EDT Update

HURRICANE EMILY DISCUSSION NUMBER 29
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
11 PM EDT SUN JUL 17 2005 (edited~danielw)

AIR FORCE RECON REPORTED A PEAK 700 MB FLIGHT LEVEL WIND OF 134 KT IN THE NORTHEAST QUADRANT AT 0018Z. NORMALLY THIS WOULD CORRESPOND TO A SURFACE WIND ESTIMATE OF ABOUT 120 KT. HOWEVER...THE CENTRAL PRESSURE HAS BEEN RISING STEADILY AND IS NOW UP TO 955 MB.
THEREFORE IT IS ESTIMATED THAT THE INTENSITY IS JUST A LITTLE LOWER AT THIS TIME...115 KT. THIS IS STILL CATEGORY FOUR STRENGTH...AND EMILY REMAINS A FORMIDABLE HURRICANE.
RADAR IMAGERY FROM CANCUN SHOWS THE EYEWALL STRUCTURE FLUCTUATING...BUT WITH NO DEFINITIVE
INDICATIONS OF AN EYEWALL REPLACEMENT. NOT MUCH CHANGE IN INTENSITY IS LIKELY BEFORE LANDFALL IN A FEW HOURS.

A HURRICANE WATCH WILL PROBABLY BE ISSUED FOR A PORTION OF THE WESTERN GULF OF MEXICO COAST...INCLUDING THE SOUTHERN TEXAS COAST...EARLY ON MONDAY.
