Hurricane Debby
07:22 AM EDT - 22 August 2000

11AM Udpate:

The Bahamas has put up Hurricane Warnings for the Acklins, Crooked, Inaguas, Ragged, Turks, Caicos, and Mayanguana Islands. (Most of the SE Bahamas)

Debby is still a minimal hurricane, but shows signs of strengthening now. The track will take it oh so close offshore north of Puerto Rico. The thinking for the remainder of the future track remains unchanged from the original Update.

Original Update:

Right now Hurricane Debby is over the northeastern Caribbean islands. Very near St. Maarten now and still moving West Northwest. God bless those in the islands, weather the storm well.

Hurricane Watches are now up for the extreme Southeast Bahamas.

What of the future? It's still a little questionable, and note it go either way from here, but my thinking puts it continuing West northwest and passing Hispaniola just to the north (but close) and offshor a bit to the Northeast coast of Cuba late Thursday and approaching South Florida on Friday. Caveats here include, not turning north and going into the Gulf, and turning north affecting Central Florida or further up the SE coast. The most likely includes an approach to South Florida and possibly turning up the state once within. Models however are leaning toward the south. So the Gulf scenario has a decent chance too. However, past the point of "near Florida" it becomes speculation to the Nth order.

How strong will it be? This depends a lot on how much, if at all, it goes through the larger islands (like PR and Hispaniola). If it does, it will be weaker, if it does not it will most likely slow down Tomorrow or Thursday and be allowed to strengthen. I have no idea what type of system Debby will be when it approaches Florida. It has the potential to be a major, but I'm not totally convinced of that yet.

Debby will affect Florida in some way somewhere during Friday and this weekend. Know this, and plan for this. I realize that is a broad statement, but it's impossible to say any more with confidence yet. And listen to local Emergency Management, Media, and other official sources. You can help us out by letting us know what you hear via local media or anything by leaving a comment here to help seperate information from misinformation.

Is that an eye? (#1)

Well i have just viewed the first available visible sat imagery, and it looks to me like an eye is trying to form. The apparent eye is located just to the southwest of Barbuda, midway between that island and the islands of St.Kitts and Nevis. Obviously the image is the first visible, so the whole storm is not completely illuminated. However the apparent eye would be close to where NHC say the centre of the storm should be. IR imagery would seem to indicate that if this is an eye it is located to the south of the bulk of the convection. However there is convection completely wrapped around this apparrent eye. It looks as if it mmay pass directly over St Kitts, as well as Saba and St. Eustatius. It will be interesting to see what will happen with the storms intensity and organisation if this is indeed an eye!
well we will have to wait for more info and more images to see if i am right or not!


Debby does the Gulf (#2)

Posted On 07:27AM 22-Aug-2000 with id (QURNQVSNRPQNXR*)


More models than not are showing her entering the Gulf. If she does, she will likely at least reach a Cat 2 by then.....with the mountains and land areas taken into consideration...No matter where she goes..this one has all the potential to be a problem for someone. Time to batten down the hatches...again...just a great site...keep it up...

Hopefully she won't hit Mobile...

I attended the live chat last night and have been using this site for information for two seasons. I want everyone to know how helpful CFHC is! It would be easy to induce panic with wild forcasting, however, the posters and moderators are well informed and thoughtful with their insights. I appreciate the professionalism of all involved.

I am a weather watcher and, some would say, a frustated meterologist. Because of what I am learning, I am better informed and hope one day to contribute my own comments.

I continue to follow this and future storms with the help of CFHC.

The GFDL Animation at http://www.essc.psu.edu/rhart-cgi-bin/gfdltc2.cgi?time=2000082206-debby07l&field=Sea+Level+Pressure&hour=Animation shows a cat 3 or 4 system near Grand Bahama island on Friday. For what it's worth... (Not much) but it is in line with the thinking in the article.

Just from whatI can see now on visible satellite imagery, an eyewall is trying form and it also looks as though PR will NOT get a direct hit, which is not good for Florida as it allows the system to miss the mountainous(sp?) area and gain strenght. The latest I can tell and this is what I have gleaned from TWC is that it will enter somewhere along the SE Florida Coast, move up the center of the state, and then possibly cross out into the gulf around Central Florida. The reason they say this is because of a boundary? that is forecast to be lying right across Central Florida (above Tampa) at this time that would stop it from going further north. That's all I can say, I am not a meteorologist, don't pretend to be one, only go with what I see and have learned on different sites. And my gut instinct on this one is not a good feeling. So, prepare for the worst, hope for the best, and we will see what happens. Colleen

I have made changes in the way the officila information is updated on the main site. (Ie those pop up texts on the main page) It's in "high traffic" mode which hopefully can deal with the massive influx of people we have been getting to this site. The times when the data is incomplete should be much more infrequent now. I'm working on a larger fix which will eliminate the problem entirely, but it is more complicated.

Shortly the NWS "Area forecast discussions" for Miami and Melbourne should start to appear, because they will discuss Debby and the local thought.

Water Vapor (#7)

Posted On 09:50AM 22-Aug-2000 with id (RPVNRQUNRRQNRUR*)


Looking at the water vapor image, it seems like the ridge to the north of Debby really breaks down after it hits the Bahamas. Until I saw that, and with Debby's more northward movement than expected, I had though she would go into the gulf.
Now, it looks like Florida is more likely. These high pressure ridges move from the west to the east and to the west of the high pressure ridge is a definate break in the ridge.
I think the question now will be how far off the coast of Florida she will be. After all, the models that show her going into the gulf were initialized before she started heading more west northwest than west. We should see a significant change in the track with the 5 pm forecasts, if not in the 11 am forecast.

northward movement (#8)
Posted by: jimmy
Posted On 10:00AM 22-Aug-2000 with id (RQVNWWNQUWNR*)


the discussion this morning stated that there would likely be time when she would move more northerly and times when she would move more westerly. I don't see any reason why the forecast track should change significantly. She is still going to pass very near PR and Dominican Republic. Has anyone seen the San Juan Radar Loop. If so can you determine if the center is northeast of PR now.


Watches for Florida? (#9)

Has anyone heard anything regarding possible watches for Florida in the future? Would they go up Wed. p.m.?

eye wall (#10)

on the latest visable shot, there appears to be a possible small eye wall forming on the far western part of the cdo. Does anyone else see this?

Hello Richie
As it looks right now and watches for Florida may be posted some time late Wednesday with warnings sometime Thursday if there needed at all. Nothing is in stone yet!! BUT!!! I believe they will happen(opinion only)...

Posted On 10:27AM 22-Aug-2000 with id (RPVNRQUNRRQNRUR*)


I didn't mean a change in the short term track. I just think the track at 72 hours will be more north than what the NHC has been saying.

Hmmmmmm... (#13)

Posted On 10:29AM 22-Aug-2000 with id (RPUNRTRNRRXNSQ*)


I have to admit that it is looking a little more likely that Debby will impact Florida. I'm still crossing my fingers for a northward turn and shimy up the coast and away and nothing direct. I shudder to think what Debby might get up to if her forward speed slows a bit and she hits that very warm water near Florida and Cuba. Truthfully, my biggest worry is a possible knife cut up the middle of the state. That would really spread emergency services thin.

PURE CONJECTURE (#14)
Posted by: GREG
Posted On 10:33AM 22-Aug-2000 with id (RPXNVQNRRWNSP*)


AS MY SUBJECT TITLE INFERS...WHAT DO I KNOW....BUT HERE GOES. WATER VAPOR LOOPS WOULD SEEM TO INDICATE TO THIS TRACKER THE STORM SLOWING DOWN FORWARD SPEED BY LATE EVENING EARLY MORNING AND STAYING SOMEWHAT NORTH OF HISPANIOLA-THEREFORE NOT HAVING STRENGTH SAPPED. A MORE NORTHERLY COMPONENT TO THE TRAJECTORY COULD OCCUR TO THE WSW TRACK PUTTING AN AREA SOUTH OF WEST PALM BEACH AT RISK FOR SOME LEVEL OF LANDFALL WITH A RIDE UP THE FLORIDA COAST AND SPOTTING JUST OFF THE COAST BETWWEN DAYTONA AND JACKSONVILLE. COULD EVENTUALLY SEE ANOTHER LANDFALL AROUND CHARLESTON S.C. OR NORTH. I JUST SEE A WEEKNESS IN THE RIDGE AND TROUGH CONTRIBUTING TO THE EAST COAST RIDE. UNFORTUNATELY A RIDE UP THE COAST WOULD DAMAGE ALOT OF SHORELINE. HOPE I'M WRONG AND THE EAST COAST AND GULF ALL STAY CLEAR. MAYBE IF SHE SLOWS DOWN ENOUGH THIS COULD HAPPEN.

Gulf Stream (#15)

Posted On 10:44AM 22-Aug-2000 with id (QSWNURNRPPNRQQ*)


Well, the models have split, leaving the TPC/NHC in a black hole. It appears that once Debby enters into the waters between S. Fla, Cuba, and the Turks and Caicos, it becomes nothing short of speculation. With all the variation in the models, a negotiated position places it on top of S. Florida. I am beginning to lean toward the presumption that Debby will slow dramatically once in this area. Being that I am in agreement with Snonut's page, I see at least a (3) or (4) jogging it's way, causing predicatability to become rather questionable do in large part to her strength. This storm will begin to greatly resemble Andrew in it's small tight physical characteristics within the next 60 hours, watch and see.

South Florida Water Management (#16)

I just heard from someone who was at the South Florida Water Management District offices in Osceola County. They were told that it was time to start buttoning up because the official forecast past three days had Debby entering the state at West Palm Beach and then leaving the state near Daytona Beach.
As he was leaving, the offices were putting up the hurricane shudders.
Also, the new advisory has Debby about 100 miles off the tip of Florida Friday at 11 pm heading NW towards West Palm Beach as I said before.

I just wanted to mention to everyone on the east coast do not let your guard down. As it has been stated the models are split on this one. My personal opinion (and only my opinion) is that it will have some impact on the florida east coast and move northward. Everyone from southern florida to the carolinas should be prepared.

They have changed Debby's path in 72 hours from just North of Cuba, to just WSW of what appears to be Grand Bahama Island (just West of Exeuma Sound). With this change in their forecast, and the likelihood of missing Hispanola, this storm has the potential to become a major. If buying insurance, the storm will be in the box tomorrow morning!


Debby... could slow and intensify (#21)

Richard Byett (http://www.atlantic-technologies.co.uk) Location: Gloucester, England, UK
Posted On 12:46PM 22-Aug-2000 with id (RQRNQSYNSRNVQ*)


Well if Debby slows then it will encourage intensification, and i think this is the most likely. If she slows down then the LLCC will be able to stack with the midlevel low. There are indications that convection is trying to wrap around the llcc, but it will need to slow a little before that really takes of. There are indications that within 72 hours this system could be a CAT 3. And then Florida will need to keep a close eye on this potentially major hurricane. In fact Florida should monitor this closely now, as it looks to threaten the south-central Florida east coast by the end of the week, and as a potentially major Hurricane.

trough (#24)

Posted On 01:07PM 22-Aug-2000 with id (SXNSQNQTYNRTV*)


it looks to me that the trough over n. fl. is not digging south. if debbie travels much farther west it is likely that it would slip under this trough and not be pulled northward. Winds in the gom are traveling east to west. looking for this system to be over key west in 72hrs.

strengthening (#27)
Posted by: jimmy
Posted On 02:15PM 22-Aug-2000 with id (RQVNWWNQUWNR*)


there appears to be some convection wrapping around the west side of the center in the last few radar loops. I think the strengthening has begun.

that convection is getting closer and closer to wrapping completely around the center. Will be at least 80mph at 5pm.
