Day 1. Tropical Storm Barry Forms in Gulf of Mexico

10AM Saturday Update
Tropical Storm Barry looked more subtropical for a time last night, however, the low level circulation center has remained intact and convection is again beginning to build just north of the center. Barry is now moving northeast at about 15mph and the storm should make landfall in the Tampa Bay area prior to 11am. Barry will move across the state taking a northeast to north northeast direction with an increase in forward speed. Maximum sustained winds near the center are 45 to 50mph and the storm is likely to maintain winds of 35 to 40mph near the center as it crosses the Florida peninsula.

A developing feeder band extending south from the center will move across the peninsula and bring a threat for strong thunderstorms and isolated tornadoes later this afternoon. A Tornado Watch is in effect until 3pm.

During the night a strong convective cell move along and just inland of the Florida east coast from Ft Pierce northward and produced some significant rainfall with storm totals (through 02/12Z) of 4.65 inches at Satellite Beach and 6.00 inches at the Melbourne NWS.
ED

7:30AM June 2 update
The center of Barry is still offshore, southwest of Tampa. And the forecast track has moved to the right, now landfall should be north of Tampa. Most of the rain is to the North and Northeast of the center, so Central Florida has seen most of the heaviest of the rain it will get already. However, a Tornado watch remains up until 3 PM today for much of the area.

The big Bend of Florida and Northern Florida will continue to get heavy rain for a few more hours.

Convection surprisingly fired up a bit more this morning near the center, but the low level center is likely to fall apart very quickly as the rest of the convection races across. Similar to Alberto.

Let us know conditions in your area here



7:20PM update
Recon reports pressure drop to 997mb. Range of 50-60MPH winds. Strongest winds are on the western side of the convection though. Interesting to see how much longer it can hold together at this strength. The pressure dropping trend seems to be at halt,since soon after that recon report it appeared that convection was starting to fall off.


6:55PM update
Indications are that the northeastern movement (along the path of the cloud blow off) is occurring earlier than expected, likely making the landfall point a bit more east. But in such a storm, it won't make much difference.

Barry does have a lot of lightning associated with it (See map), which is unusual for a Tropical Storm.

Original Update
Tropical Storm Barry has formed in the Gulf of Mexico 320 miles southwest of Tampa, FL.

Tropical Storm warnings are up for the Florida west coast from Bonita Beach up to Keaton Beach.

Recon aircraft found around 1000mb of pressure earlier, and found a pressure of 1000mb, and with a slightly strengthening system, it was enough to classify it as a Tropical Storm. The second of 2007, on the first day of the season.

More recent recon has found a slightly stronger system with 998mb of pressure. Equates to roughly 50-55MPH (in better conditions maybe even 60MPH) winds. Tornadoes may be caused by this system. See the local storm statements. The system may strengthen just a bit more, but most of the convection is getting blown off to the northeast, sending most of the rain to Florida (and we can use it).

As for impact,
o Flood preparedness
o Tornado awareness
o Basic essentials for power failure
are the big three for Barry. Other than some beach erosion, surge will fairly low impact. Wind will be gusty near the core and where heavier convective elements transfer some of that flight level momentum into the boundary layer. Otherwise, not a very big concern there either.

The heaviest rain for Central Florida will be between 3AM and 3PM tomorrow.

Barry will be interesting once it crosses Florida and interact with the dynamics of a trough amplification. It should be well involved with cyclone phase transition at that time.

Earlier Update
The 2007 Atlantic Hurricane Season begins today, and we are watching a system in the western Caribbean that may bring rain to Florida.

The system still isn't likely to develop much, if at all, as conditions for it doing so are becoming more hostile.

See Clark's blog below for more information about this system.

Although we always hope for another inactive season, this year is expected to be an above average year for storms, so it could get busy. Normally June is a slow month, as the season really doesn't start to get going until August.

Flhurricane is a non-profit site, but still requires resources to run, we emphasize quality information over quantity, and focus on the information with an outlet for communication. We do not celebrate the arrival of hurricanes or hurricane season, as the point is to help keep people informed and encourage using multiple sources of information to help make decisions, always preferring the use of official sources over unofficial ones.

Re: Day 1. Tropical Storm Barry Forms in Gulf of Mexico

Through the evening, I will be curious to see if this is one of those "Thunderstorm chaser" Systems that we have seen a couple of in recent years over 'round this side of the Gulf. Perfect examples being Earl in '98 and Gabriele in '01. These storms get an established center, the thunderstorms shear off to the NE and a new, slightly stronger center reforms to theNortheast under the thunderstorms time and time again until landfall or system decay. This may be a classic candidate for that now,and if it does so, I'd expect a landfall around Tampa or a bit further south as a moderate tropical storm, but nothing more. Either way, I wouldn't expect anything too strong along the western coast and we are gonna get some much welcome rain! Too funny! I wrote this thing off last night. That tasty crow is mighty delicious! LOL :-)

Re: Day 1. Tropical Storm Barry Forms in Gulf of Mexico

92L being verified as a Tropical Storm is not terribly surprising to me, although admittedly still a bit of a "Wow, on June 1, no less!" moment. Color-enhanced satellite loops as early as last night were strongly suggesting that a tight and at least somewhat warm-cored coc had already formed. Will make for an interesting read when HRD gets around to it.

Would like to point out an earlier ship report that lends a strong voice, when taken with the most recent recon data, for another upgrade tonight.

Barry reminds me of Alberto, and more than a little bit. With him attempting to form a tenuous eyewall, just about all afternoon, I think he stands a pretty good shot of developing a small, but noteworthy core of very strong TS/perhaps marginal Cat 1 winds. Of course, Alberto wasn't exactly known for his ferocious winds, but he also worked on trying to put together a respectable eyewall just before landfall, and there is reason to believe that a small core of 70MPH surface wind really did exist.

Re: Day 1. Tropical Storm Barry Forms in Gulf of Mexico

Well the latest Vortex Data message has estimated surface winds at a little under 60 mph, and maximum flight level winds of near 78 mph. Interestingly both measured in the left hand side of the storm - not on the right where most of the weather is. Could we see Barry noticeably stronger than forecast... maybe even making it to Cat 1? Well given the visible presentation i would say no, but given the aircraft data, then that does become quite a real possibility.

EDIT: Latest vortex data has pressure down to 997 mb

Looks like we will get off to an early start into this season. Could someone tell me more about the lightning issue? I know it is very unusual for tropical weather to be accompanied by lightning. Lightning is the last thing that we need here in central Florida. Any clue why this storm has it when others tend not to?

Either it's not purely tropical (likely), or sometimes in rapidly strengthening storms lightning has appeared. Barry is a little bit of both, but I think the strengthening part has ended.

Re: Day 1. Tropical Storm Barry Forms in Gulf of Mexico

Hail aloft is often very important in creating the static which results in lightning. Most thunderstorms within Tropical Cyclones do not produce copious hail, however. In fact, most thunderstorms within classic TCs are rather low-topped, that is to say, they do not reach way up into the upper troposphere as do severe thunderstorms which form over land. This is in no small part due to the temperature profile both in the vertical as well as horizontal of TCs. Rapidly strengthening and/or very strong TCs occasionally do produce tremendous amounts of lightning, and even hail, as their thunderstorms can respond to this intensity in such a way that they are essentially strong to severe cells within the larger cyclone.

(This is all a bit of a quick and dirty description).

Re: Day 1. Tropical Storm Barry Forms in Gulf of Mexico

Well, Shiver me timbers!

Barry made the tropical transition that almost everyone *did not* think would happen, even myself.

I was looking at the very first visible pics and mentioned earlier an another post that it was looking alot like a sub-tropical system, at best. And there really wasn't much in the way of deep convection near the center.

But, alas! The deep convection finally did flare up, and despite the shear, began wrapping around the center, and with each passing visible pic added to the loop, it became apparent that cyclogenesis was unfolding before our eyes!

I too, eat crow. It just goes to show, folks, that with all our computer models, all the advanced analysis tools and the elaborate, 'high-brow' postings from our many very knowledgable members to this forum, that good 'ol Mother Nature has the final say and, often, she throws a curve ball just when we were expecting the slider.

But keep it up! There have been many very insightful and educational postings. Great forum. Learning tons! Thank you all.

I am so happy for the good folks who will be getting the drenching we've all been praying for so long.

I heard it's been dubbed 'Benifical Barry'. A true Godsend for the parched peninsula! THANKS BARRY!

Well... I was among those who thought the same thing you did, until this afternoon. Now, I'm beginning to return to that camp, based upon the last several AVN images. While Barry was very much tropical in structure at the time of the 5pm advisory, I think it's already losing its tropical characteristics, due to shear and the rapid movement.

Edit: I just loaded the visible loop, which shows the LLC in the overnight IR, and I was completely wrong about the movement. It looks as if the LLC actually isn't moving much... maybe drifting due east... but the shear has pulled Barry apart.

Re: Day 1. Tropical Storm Barry Forms in Gulf of Mexico

The circulation is completely exposed now as seen on the last visible images of the day. The intensity has probably peaked for this storm. However--as is common with these systems--we might see another flare-up of convection near the center overnight. Either that, or it transitions quickly into an extratropical system. Seems to me that this system will become extratropical sooner rather than later. The rain area will probably exit the west coast of Florida by midday Saturday and then there will be a strong, dry onshore wind from the exposed circulation ala Gordon in 2000.

Here in Pinellas County, we have been experiencing steady rain for several hours...1/2" so far. The wind is just starting to pick up with gusts in the range of 20-25mph.

Re: Update

The last 7 hours the llc has moved little. The convection has been blowing off to the NE. There has been a bit of an increase of convective activity on the east side which is good as it will spread across the FL peninsula since we need the rain. I am a little surprised that the earlier convective burst didn't pull the llc more to the NNE.

Re: Day 1. Tropical Storm Barry Forms in Gulf of Mexico

Well, Barry is looking mighty pathetic tonight. Maybe I bit the bullet a little too soon with my commentary on the models earlier? Not sure. Anyway, it looks like the upper low in the Gulf has decided to move east after all, which is slowly pushing the storm in that direction as well. The general flow is out of the south, but the overall progression of the entire mess to the east is sending the storm on a NE path right now.

As a result, I've gotta back off of my Big Bend/W Cent Florida idea and come down to the Tampa region landfall-wise. This is due to a lack of vertical coherence plus a bit more of an impetus to the upper low to move east. Complicating factors could come if the center does reform closer to the convection, which is still headed for the Big Bend/Cedar Key area, but I don't know how likely that is right now. Hopefully the diurnal convective max gives us some ideas.

Tampa Bay 10 meteorologist Dick Fletcher predicting 3-6 inches of rain for the Tampa Bay area and storm surge of 3-5 feet. Wouldn't surprise me, we've had 1.3 inches already in Cortez, S. of Tampa and it just started coming down hard again as I type. Localized coastal flooding is also predicted.

This is a good start to the season, perhaps this TS will serve to remind people to stock up, make plans, and prepare for what is supposed to be a very active season. It's harder to get into hurricane mode when the sun is shining and we're in the middle of a drought.

Actually alot did speculate it had a good chance.. me included. I stated last night recon will check it out and there was a good chance it should be Barry..but it was up to the data the recon showed.Barry I still feel will be south of the NHCs landfall from Ft Myers-just north of Tampa Bay (Pasco) The storm is not purely tropical anymore...its last breathe was this evening....it should hold its own or strengthen more..but as a extra-tropical baroclinic low...as i feel its been transforming now. Still nonetheless....winds of 50-60mph near the landfall and squalls later on Saturday especially over S florida and eastern florida with the S and SW flow. Tornados are likely south of I-4 with a slight chance north. Rainfall amounts will range from near 1-2 inches in N central florida...to 6-8 inches in parts of S florida and along the west coast to TampaBay.

This was a nice start to the hurricane season...and florida needed this rainfall.

Barry is now an extratropical system, although the NHC will probably maintain the tropical designation until landfall for the sake of public awareness. The center of circulation is stretching out SW to NE and most of the heaviest rain is in a single band along the west coast of Florida northeast of the center.

In looking at the Tampa Radar loop it looks like two centers swirling out there. One is "Barry" near Sarasota moving northeast and the other is out in the Gulf about 100 miles off Hernando/Citrus County. Is the second one the mid or upper level low that moved into the western Gulf on Thursday that is pushing Barry along?

Nope not yet, he's still got some good flare ups near the center before making landfall... I still say there's an outside chance of him gaining 60 mph. winds if the convection could blow up more. He's still at least Sub-tropical.

Re: Day 1. Tropical Storm Barry Forms in Gulf of Mexico

It looks to me, based upon the Tampa radar loop, that the actual LLC of what is left of Barry is just offshore, and moving up the coastline, north of Tampa. Either that, of the LLC is due north of Tampa, onshore. The thing is so disorganized now that I can't determine which quasi-spin I'm seeing is really what is left of the LLC.
If I go to the Tallahassee radar I see what appears to be a broad circulation moving onshore SSE of Perry. In the end it's really not important, because the whole area is getting drenched with much-needed rain. Those of us west of Panama City are getting hung out to dry, though.

Edit: 11am advisory confirms position of the now-downgraded TD Barry as north of Tampa, onshore.
All watches and warnings (other than tornados, of course) have been discontinued.

Edit2: Interesting bit from the discussion.. Barry and Barbara made landfall within about an hour of each other.
Any chance that the remnants of Barbara could sneak into the Bay of Campeche and reform?

Re: Day 1. Tropical Storm Barry Forms in Gulf of Mexico

I think the LLC went ashore near Sarasota near 10:30 or so. There wasn't much to it.

The other feature you're seeing is probably that low that entered the Gulf on Thursday off of Texas and Mexico.

Right now the low out there now has shifted winds to the southwest here. If Barry had been more organized we would have a northeast wind since he went in south of here, but that didn't happen.

assault of the midget B-storms

barry's center became elongated in the early morning hours and it is steadily undergoing extratropical transition. the deep convection bursting (maybe due to increased friction at the coast) this morning probably helped stay any itchy trigger fingers at the nhc to call it extratropical.. recon still shows it as weak warm-cored for now. my folks are taking a beach trip to pawley's island, and it just figures that after weeks of dry, warm (but not really hot) weather an ex-tropical storm is going to shellack them on day one. barry's legacy will be mostly favorable, with a decent rainfall blanketing some of the most parched areas in the southeast, and a quick advance precluding the kinds of problems a slow moving tropical storm can cause. might be a few severe cells in the right front quad with daytime heating and the clear dry air intrusion into the core across north florida today, but probably nothing else of note. the folks on the carolina beaches will need to be wary in the surf, though.
barbara is fairly weak and coming in with little momentum... i greatly doubt that anything of the center will survive across central america. the system is fairly small and the threat of severe rainfall should also be limited. the nhc guys already noted a tilt with height, so it'll probably just decouple and wash out fairly quickly. the conditions on the atlantic side would be fairly favorable, but there isn't a strong convergence point or disturbance there to take advantage of things, as barry took most of the good low-level dynamics out with it.
next chance of anything interesting is the next northward moisture surge from the western caribbean, scheduled for about mid-month, which the gfs keeps insisting will happen run-to-run. considering it's overall long-range performance with barry, i'd say there's a reasonable chance we'll be watching another feature of interest around about june 13-15.
the pattern is de-amplifying, so there isn't much else of a chance of more tropical development.

Re: assault of the midget B-storms

its actually *sunny* in New Smyrna Beach, Volusia County, and we still would need some good downpours of rain. Looks to me from here that Barry is fizzling out...

Re: assault of the midget B-storms

Im not going to add more then what Hank just added. Barry came ashore near TampaBay-Sarasota as a TD. Weakened alittle faster due to some dry air. Infact...most were hoping for more rain today from this. Barry peaked out yesterday evening and then took in some drier air from the western gulf..and also started its transition to extra-tropical.

Re: assault of the midget B-storms

I know Barry is gonna be extra tropical when it gets to SC/NC and it's moving fast but could it possibly strengthen even as an E.T. system. I'm in NC and my local news website has this about the waters off of our coasts. see the attached file. [image]http://wect.com/Global/story.asp?S=5227117[/image]

Re: assault of the midget B-storms

As of right now at 4pm where exactly is the "center" of Barry located? I'm tracking the strm (or at least calling myself tracking it).

Re: assault of the midget B-storms

The new (likely final?) advisory on Barry will be out within the hour, so that will tell you exactly where its remnant low is. On the visible satellite I see a spin offshore, but on the radar it looks like it's nearing the Jacksonville area.

Edit: Advisory was indeed the final one on now-Extratropical storm Barry, and it was indeed located near Jacksonville.

Re: Day 1. Tropical Storm Barry Forms in Gulf of Mexico

Well, Barry did what we expected in the end, and that's bring some needed rains to parts of SE Georgia and the Florida peninsula. General totals will be in the 2-3" range with a few spots closer to 5-6", it appears, without really any flooding concerns. All in all, a needed soaking rain.

Looking back on it, out of all of the available model guidance, the ECMWF did the best with this one. It was largely consistent on a track near or just north of Tampa throughout most of its runs over the past several days. The GFS was probably next best; not nearly as consistent but did better toward landfall. It also showed the mid-level and surface circulations being decoupled from one another, which actually did happen. Every time convection flared, a new mid-level center would get shot off to the north while the surface circulation turned more northeasterly. Most of the rains in my neck of the woods came from one of the mid-level centers, in fact. Good call by the GFS there, even in the face of some signs to the contrary at times.

The NAM didn't do awful with this system, but it had the wrong idea in keeping the storm vertically coherent in the face of the strong vertical shear across the Gulf. If the system had stayed upright and vertically coherent, it likely would have made landfall near where the NAM suggested -- further north and west -- but alas, it did not. Not sure what part of the NAM analyses you can chalk that up to, but I'm guessing to a tendency to overdo warm core structure nowadays.

Re: Day 1. Tropical Storm Barry Forms in Gulf of Mexico

Well, here in Atlanta it seems we have been right on the edge of the rain all day...but not a drop here in the city. The air has just been so bone dry the precip isn't making it all the way down. At least the fires in SE GA will be put out by Barry so we wont wake up to the "smoke fog" thats been in the air for the past couple of weeks. I'm sure several locations will be thankful for that. Hats off to the firefighters in FL/GA. This has to be a blessing to them

Re:Clark

One thing to add to the performance of the ECM is that it latched onto height falls over the GOMEX well ahead of the GFS. From my SAT 5/26 AFD...


"THU-SAT...MED RANGE MODEL GUIDANCE SUGGESTS AN INCREASING CHANCE FOR
A MUCH NEEDED WIDESPREAD/HIGH COVERAGE RAIN EVENT LATE NEXT WEEK AS
WE HEAD INTO JUNE. CONTINUED AMPLIFICATION OF THE WEAK SRN STREAM
TROUGH IS PROGGED TO OCCUR OVER THE GOMEX BY BOTH THE 00Z ECM AND
12Z GFS. ECM IS MUCH MORE ROBUST WITH BOTH THE H50 TROUGH...AND THE
SURFACE RESPONSE...HOWEVER BOTH SOLNS SHOW ENOUGH AMPLITUDE TO ALLOW
DEEP LYR FLOW TO ACQUIRE SIGNIF SRLY COMPONENT TO ADVECT DEEP
TROPICAL MOISTURE NWD INTO FL. BY FRI/SAT...THE ECM SHOWS A MORE
CUTOFF/SLOWER SOLN...WHILE THE GFS LINKS THIS WEAKNESS UP WITH THE
NRN STREAM...CREATING A BROADER MORE FULL LATITUDE TROUGH. IT'S
HARD TO IGNORE THAT THE GFS HAS OFTEN FOLLOWED THE ECM'S LEAD WITH
THE CURRENT PATTERN...AND IT IS ENCOURAGING TO SEE BETTER AGREEMENT
BTWN THE TWO...THOUGH IT STILL IS IN THE DAY 4+ TIME FRAME."


Additionally, I distinctly remember much stronger height falls working toward the GOMEX on the H144/H168 panels of the FRI 5/25/12Z run of the ECMWF compared to the corresponding run of the GFS...hence the "IT IS ENCOURAGING TO SEE BETTER AGREEMENT BTWN THE TWO" comment from this AFD, issued the following day. More kudos for the ECM, which is usually the stellar performer amongst the globals in its depiction of the H50 height fields over NOAM/CONUS.

Re:Clark

The remnants of Barry actually look better organised now than ever as a Tropical Cyclone. although according to the HPC the centre is inland, early visible imagery shows a developing convective band wrapping around off shore of the GA / SC coasts. However, IR imagery shows that the convecion is shallow and weak, and at present there is little reflection of this wrap around in the latest radar imagery.

Secondary Circulation ??

Morning All,

Not too sure if this is the proper place to post this ...
It does contain the most recent threads, and, since Barry is no longer tropical,
I didn't think that the "Tropical Storm Barry" forum was a good place, either.

Perhaps we need to start a new thread (forum?) for extra-tropical 'Barry'.
Feel free to move this posting if you do so.

Now then ...

I'm checking out the satellite and doppler loops for ex-Barry, and I'm noticing something rather curious.

It would appear that there is a smaller circulation center that's been rotating through SE Georgia, now just exiting into the Atlantic, near the Georgia/South Carolina border, that appears to be embedded within the much larger overall circulation of the now extratropical Barry remnent. (Please view the attached satellite photo.)

I remember reading in these forums a day or two ago that a "piece of energy" might get 'left behind' as the overall, larger circulation accelerates off towards New England.

Question: Could this bit of 'vorticity' break away when ex-Barry pulls away, and languish over the Gulf stream for possible (sub?)-tropical development down the road.

Or, am I just noticing the ''inner sanctum" of the overall extratropical circulation that will eventually 'wrap' more towards the center, instead of it currently being *distinctly* in the SW quadrant of the overall much larger circulation.

I'd be interested in hearing from our forum meteorologists what their take is on this little 'will-o-the-wisp' of a 'circulation center'. Is this common with freshly transitioned systems when they acquire non-tropical characteristics?

Re: Day 1. Tropical Storm Barry Forms in Gulf of Mexico

Looking at the floater for the remnants of Barry, and combining this with the information in the 11am advisory from the Hydrometeorological Center, Barry's rains may be over, but the wind is actually stronger now. The advisory makes no mention of the term "tropical depression" because Barry has lost its tropical characteristics, but the NHC still shows the advisory under "Tropical Depression Barry". It's semantecs, but to me, this is sort of poor form when winds stated in the advisory are above the threshold for tropical storm strength and the pressure is actually quite a bit lower than it ever was in Barry as a tropical entity, at 992 MB.

Given the remnant low's proximity to the coastline right now, could it actually get out over water and re-acquire tropical characteristics? On the visible loop I thought it was doing just this, but the IR loop shows no convection near the center, but I think a case could be made that given the location and strength, the low is in fact a "subtropical" storm right now.

Edit: Just pulled up the Wilmington, NC, radar. It shows a poorly defined circulation, but a circulation nonetheless, southeast of Wilmington - offshore - moving in toward Wilmington.

Re: Day 1. Tropical Storm Barry Forms in Gulf of Mexico

I don't think the low has enough time over water needed to regain tropical characteristics especially with it being so poorly defined (the center). I just may be wrong but it's only my one cent.

You're probably right, especially given the water temps aren't as high in this area I imagine, but it's definately looking like an interesting Nor'easter setting up.

Something?

There is a good flare-up off the tip of the Yucatan(about the same spot where Barry got started).Does anybody have a stats on this.Does not look like there is much shear at all.Maybe something to watch? http://www.ssd.noaa.gov/goes/east/watl/loop-rb.html

Re: Something?

It's nothing to worry about, just an afternoon convective flare up from a trough.

Looking around, everything seems quiet for at least a week and probably longer, nothing looks impending. No real waves, nothing really lingering around either.

The atlanta area finally got some rain, at least enough to give the ground a little to sip on. South Georgia and Florida got some critically needed rain.

Now another good soaking would be nice. Just don't see anything coming down the pipe.
