Dennis and Cuba
      #39537 - Fri Jul 08 2005 03:41 AM

8:30AM 8 July 2005
Data from the Hurricane Hunters indicate that Dennis has undergone yet another period of rapid intensification, now with a pressure drop of 12mb to 938mb and an increase in surface winds to at least 140mph. This comes from sampling the southeast quadrant; it remains to be seen whether or not stronger winds exist in the northeast quadrant. At the very least, a bump up in intensity will occur at 11am.

7AM 8 July 2005
Hurricane Dennis has remained a Category 4, even after being slightly disrupted by the Cuban peninsula earlier. it still has more of Cuba to go over to once again get disrupted, but in the meantime it is over very warm water now and has a chance to hold or strengthen its current strength until that happens.



This has a potential to devistate the areas over Cuba it crosses.


After Cuba, it will pass very close to Key West (maybe just west) -- close enough to feel hurricane strength winds. After which it will move northwest into the Eastern Gulf. Probably 150 miles or so west of the west coast of Florida, staying far enough offshore that the hurricane winds won't be felt along the west coast, although tropical storm force may be.

The short term 24-48 forecast track has been very good so far and the ultimate track is still trending some where along the Panhandle west toward New Orleans. With the highest probability near where Hurricane Ivan hit last year. The chances for a peninsular hit in Florida are dropping quickly. Which is good news for us in Florida. However,e it still has not cleared Cuba, so we must watch it. Probably until it passes north of our latitude. Still there is no reason to doubt the National Hurricane Center track. This would have landfall sometime late Sunday or Early Monday.

I know the folks in the Panhandle and Alabama do not want to hear this. And my heart goes out to them.

Please listen to local officials and or media as the storm nears. Follow any evacuation orders necessary. But do not evacuate unless you are asked to or live in a vulnerable area.

Original Update
Category 4 Hurricane Dennis is now approaching Cuba and will landfall, maybe twice, over the island. It's likely to be disrupted somewhat and weaken, although how much is up for debate.




The forecast track still points toward a western Florida Panhandle, but those west toward New Orleans and Eastward along the Western coast of florida will still need to watch Dennis. After Dennis crosses Cuba we should know more.

Hello to all! I'm so grateful to this board and all its posters. I would go NUTS waiting on updates from other sources. What time do the next model runs come out? I'm trying to keep my eyes open (it's as if I watch and listen, I can somehow direct Dennis the other way.) Thanks for the info.

Posted this in the other talkback just as this one was created so here goes again...

Around what time do they become available publicly. I assume 00Z is midnight eastern time. How long after then until we can access them?

I, too, got caught in the old thread with my reply, so here goes...

00z is midnight Greenwich Mean Time, or along the Prime Meridian to our east. Currently, it corresponds to 8p ET. Model guidance from that time is just starting to come out and should continue to do so through the rest of the night, depending upon each model and the computing power available to it.

The 00Z refers to Zulu Time (GMT) so subtract fours hours to get EDT. I have found it takes about 4-6 hours after the model start time to get the info

Depends upon which site you use to get the data and how fast they get it. The GFS is coming out right now and can be seen directly from the source at http://www.nco.ncep.noaa.gov/pmb/nwprod/analysis/namer/gfs/00/index_l.shtml other models will be available elsewhere and also at various times through the night.

Best advice: don't wait up on the 00Z model runs and just get some rest tonight. We'll all need it soon enough, I'm afraid.

EDIT: Speaking of the GFS...its landfall has shifted back slightly to the east once again, now paralleling the coast from Apalachicola to just west of Panama City in about two and a half days...or late morning-early afternoon Sunday. Not a big shock and only about 60-75 miles east of the NHC track.

Am I crazy or does the 00Z GFS take Dennis right up the FL coast? I'm a bit new at reading these things!

Thanks for the prompt reply Clark. I think I'm going to have to call it a night as I've got a long day of research in the lab ahead of me. I want to take a second to thank everyone in this community for all of the insite they provide into these storms. I've tried to follow FLHurricane.com pretty religiously lately to try and help me plan what sort of emergency steps I need to take to make my lab at UF ready for a storm. As of now, it looks like we'll be out of the most severe weather, nothing like we experienced with Frances and Jeanne last year. As such, I don't think that I will take any steps tomorrow to "batten down the hatches" in the lab, but I'll have to keep a close eye on things in case Dennis decides to put a stop to the progress I've been making here. Such a scenario would put me in the lab on Sunday getting things ready. Unfortunately, the Gainesville area does not have a largely reliable weather source at our disposal. Most of our information comes out of Orlando or Jacksonville and neither of those mets pay much attention to us. That is where this community helps the most in my case. G'night all.

Clark....I love reading your posts. so may I ask what does the GFS shift mean for the peninsular and how accurate is GFS?

I haven't been able to get it to work either. I went on to NOAA site and tried to find it though. Has this cane gotten closer to the coast of florida?

it went over that little jut at cabo cruz an hour or two ago... inner core looks less symmetrical now. it ought to take half of tomorrow crossing central cuba at an oblique angle. the progs are still for the panhandle in the end.... the intensity track looks fair though i take note of the fact that hurricanes approaching the northern gulf coast usually weaken more than forecast. i was thinking okaloosa county fl this morning.. a little east over to walton/bay as of the evening. not going over any further, though. 100kt looks about right, give or take 10kt. 4PM Sunday the 10th, + or - 3 hrs.
gonna go see if i can find when the last july category 4 hurricane was. i'm sure it'll take a while.
the wave near the islands is staying active and low. it has a good chance to be something when it reaches the islands in 4-5 days.
catch y'all folks later.

Just got this on my weather bug.THIS STATEMENT RECOMMENDS ACTION TO BE TAKEN FOR RESIDENTS OF
COLLIER...MIAMI-DADE AND MAINLAND MONROE COUNTIES. HOWEVER...ANY
DEVIATION OF THE FORECAST TRACK TO THE RIGHT WILL INCREASE THE
THREAT FOR THE REMAINDER OF SOUTH FLORIDA POSSIBLY REQUIRING
ADDITIONAL WATCHES OR WARNINGS. ALL OTHER RESIDENTS OF SOUTH SHOULD
CONTINUE TO MONITOR THE PROGRESS OF HURRICANE Dennis SYSTEM ALSO. Clark,did you get my last post?

I got it to work. Just copy it, paste it, then delete up unitl the last letter. I'm seeing these models skirt the west coast of FL

two thoughts on the GFS model.

1. It looks like the initial location is too far south.

2. It has Dennis heading for the middle keys and then taking a sudden jog to the west, avoiding the keys and moving further off shore.

Is it late and I've had too many jack daniels tonight, or what would cause the sudden jolt west and then a continuation on the NW course. And, am I right on the too far south comment?
