Hurricane Debby North of Puerto Rico
02:32 PM EDT - 22 August 2000

11PM Update:
Debby continues its just slightly north of due west motion, and the longer this holds the worse this means for South Florida. The Gulf of Mexico track can't be ruled out yet either. More or less my previous thinking remains the same. The intensity of Debby when it approaches is conservatively estimated around a Category 3 storm -- * the potential is there for stronger *.

Tomorrow I would not be surprised to see the Florida Keys start to take some action (like suggesting tourists leave), not because they think it will go there, but rather because of the long time it would take to evacuate if it did.

Highest Risk Zone still lies between Miami and West Palm Beach, FL. Very subject to change, see you tomorrow.

PLEASE FOLLOW the advice from local authorities. Folks in Florida will have time to prepare between now and Friday. So have a plan ready if the storm decides to head your way. Use official sources and local media for more information.

9PM Update:
Debby has gone from a West NW motion to more of a general westward motion at this hour, which is plain to see on the Puerto Rico radar image. (Debby is beginning to move out of range of this radar) It's maintaining the 75MPH windspeed and probably will until tomorrow. The forward motion has slowed a bit to 18MPH.

Jim Williams over at
Hurricane City is doing an audio broadcast now until 11PM tonight.

Original Update:
As these series of images show, Hurricane Debby is now skirting along the northern coast of Puerto Rico. Luckilly for them, most all of the convection is on the Northeast side. It is starting to wrap around, though, which would indicate it trying to become better organized.

The future track is leaning away from the Gulf scenario (can't count it out yet, though) and more toward the South Florida northward scenario. Basically what was said earlier today on the page. We will continue to watch it.

There will be no organized chat event tonight, but we hope to do one tomorrow night. Jim Williams over at Hurricane City will be doing another broadcast tonight at 8PM. Worth a listen.

The latest GFDL run has it turning north a little sooner, but going through the Bahamas.

This image shows the GFDL prediction with a radar image superimposed over it. Showing the 12 hour error from the initial 12Z run of the GFDL.

The GFDL is not the most liked model by NHC....they are still saying a wnw track...we are by no means out of the woods yet....so don't bet on it.

A recurvature is looking a little better in some of the later model runs. I'll feel a little better tomorrow afternoon if forecasts start to verify a bit. I think any guess beyond 48 hours might be suspect right now. Especially in regards to both strength. Although, the wrapping of the eye that appears to be starting on the radar is in line with a lot of the models. Gut feeling says a Floyd scenario. Although, I think I will pick up some water and batteries tonight to be safe.

At the bottom of the article are a bunch of links. One of them is the link to the GFDL.

It does NOT mean Florida is out of the woods, not even close. If the models persist in nudging northward and away then you may have something, but I'm betting the next run shifts west again.

Good Clarification, Mike (#9)

Good job on the clarification, Mike...too many people get a false sense of security, and I think they do this time...believe me, I have seen it just a couple of hours ago at Publix. I hope it does pull a Floyd, but I am not counting on it only because I can't...it's not past my long/lat yet...Colleen

LOOKS PRETTY LIKELY FROM CURRENT IMAGERY THAT IN TIME A MORE NORTHWESTERLY COMPONENT COULD COME INTO PLAY - NOT NECESSARILLY CLEARING THE FLORIDA COAST. DOES ANY ONE HAVE THOUGHTS ON POTENTIAL SLOW DOWN IN FORWARD SPEED BEFORE ANY SIGNIFICANT RECURVATURE? ANY THOUGHTS ON THE TROUGH, AFTER HAVING INFLUENCED THE STORM WITH A MORE NW CURVE PULLING OUT AND LEAVING THE STORM ALONG THE SOUTHEASTERN COAST? BY THE WAY, HISTORICALLY SPEAKING THE TRACK OF DAVID IN 1979 IS BEGINNING TO LOOK FAMILIAR.

The first bit I wrote about the GFDL turning north was countered by the next, with the image showing that it was already too far north than the storms actual position, therefore it could be discounted. The 5PM discussion from the NHC mentions the exact same thing that I put up with the two comments and the radar/GFDL image.

So unfortunately, I see no reason to change what I said earlier.

That last bit was confusing even for me.

1. I mentioned the GFDL going north sooner.
2. I showed a picture that showed that the GFDL was ALREADY off.
3. The NHC mentioned this fact in the Discussion also.

This means:
1. I'm expecting the next UKMET and GFDL runs to be back west again.
2. Florida is still under the gun.


northward turn (#13)

Actually, the NWS in miami is saying that the wekness in the ridge will go away, and the high pressure will restrengthen, closing the weakness. The thought in Miami NWS is that debby will completely miss the trough(weakness) in the ridge and turn more westward towards the keys, which I think is unlikely. But this system is not going out out to sea or at least not unless something drastic happens. If anything it will head further west. Don't write this off!!

Looks like some serious beach erosion at the least. Hope that slight turn north means WAY NORTH.

The discussion is very enlightening..and frightening...they have not changed the track whatsoever...the closer we get, the more likely it is...I am betting watches/warnings will be mentioned (not issued) in the 11pm advisory...until then, I am studying math.!!!!Colleen

Jerry Jerrel, former director of the TPC/NHC, is now an analyst with nbc6 in Miami. He has described the trough to the north as "extrememly weak", and more likely than not to "flatten out." Therefore, his models and prediction is for the ridge to the North to weaken, and then re-build. Further, he sees a more WNW movement, rather than the NW or NNW predictions offered by others. Calling for Debbie to slice across S. Fla. More importantly, Dr. Jerrel believes that the area Debby will be entering, between the Bahamas, Cuba and S. Fla., is possibly the most favorable location for a hurricane to intensify in a short period of time, this side of the globe. Thus, he is concerned the NHC may be underestimating the future wind speeds of the system, as this is the NHC's weakest area of prediction.
With such a commentary, this only seems to support my earlier prediction of a 3 or 4 entering between Islamorada (Marathon) and West Palm Beach. Let's hope I'm terribly wrong.

Well Brian, based on what you quoted in your post it is not looking to good for us here in the S.E., I think at this point everyone/everywhere just needs to pay close attention. Like alot of others have said until it is past your longitude/latitude can we relax, have you done Publix yet? Just asking since your in my part of town and if there seems to be any concern with shoppers?

In your post, you mentioned Debby slicing through Fla. Does that mean she is likely to head on into the Gulf? What are the thoughts on this? I thought the only way Debby was going to curve N would be because of this trough. If this trough is weak, then it has a better chance moving west (and into the Gulf) Am I right or am I missing something here

Dr. Bob Sheets formal director of NHC before Jerry Jerrel is on Channel 9 news in Orlando.
He says it may go up the east coast of FL.
Go figure, each have there own prediction. So keep in mind it is still up in the air where Debby will go. Nothing is in stone after 12 hours.

Bob Burpee was director before Jerry, Sheets was before that.

From the information imparted to the public from Jerry Jerrel, it seems the high pressure ridge to the NE of Debby is going to weaken in 48 hours. At the same time, the trough MAY be too weak to lift Debby, but rather, it MAY "nudge" it northerly, and then return to a more westerly track. Remember, no one, not even Max, will have a clue until late tomorrow, or even Thursday. Hope that helps. My suggestion, check how cold the temps are projected to get in Tenn, KY, NC, SC, and GA, this will give you an idea as to the strength of the trough projected to move south on Friday.
