Throw a Dart...
09:16 AM EDT - 15 September 2000

2PM Mini Update:
The center of TD#11 appears to be reforming a little to the north and east of the current official position. Also... The wave East of the Caribbean islands is looking very good this afternoon. We may have three tropical systems to track at once very soon. -- The quick pop ups should return later in the day. (See
Eric Blake's Atlantic Tropical Weather Center for alternate advisory sources, or many other links that we have.)

Original Update:
The models are less useful than that this morning with TD#11. It really is wide open for speculation right now. We won't know much until tonight probably.

The center is still questionable, and the shearing going on as well as the general pattern around it make for any predictions to be pretty much a guessing game. To reiterate, the entire Gulf coast needs to watch this system. (I'm personally leaning toward the Eastern Gulf including the West coast of Florida, but that is just a dart throw itself.)

The folks in Tampa agree:

THIS WILL BE A VERY TOUGH MARINE FORECAST. EVERYTHING DEPENDS ON THE PROGRESS OF TD 11. IF THE AVN IS RIGHT WE COULD GET SOME 4 TO 5 FOOT SWELLS BY LATE SUNDAY. IF THE CANADIAN MODEL IS RIGHT SEAS COULD GET EVEN LARGER THAN THAT. OF COURSE YOU CAN PRETTY MUCH THROW A DART AT A MAP AND GET ABOUT AS GOOD OF OUTPUT AS THE MODELS THIS MORNING. I WILL GO WITH PERSISTENCE...WHICH PRETTY MUCH AGREES WITH THE ETA...EXCEPT FOR TAKING THE FRONT A LITTLE FARTHER SOUTH. BUT I WILL LEAVE THE DISCLAIMER STATEMENT IN THE FORECAST...BECAUSE THAT IS WHAT THE LOCAL CRS READS AND IN THE SYNOPSIS.

More to come later...

New Llcc? (#26)

TWC --Rich johnson just said the Llcc isnt moving much at all,if any. He talked more about a new Llcc trying to form under mid level cir.& on the satellite view it sure looks like it to me!!!
Boy if thats true--look out eastern part of the Gulf especially Florida!!!

I think it is very clear now on visible sat pix that this is definitely what is happening...and fast. I will interested in seeing what the good Dr. has to say at 1:50pm.

Look at the w.v.loop...what I see here is an upper low digging in over Yucatan from nw to se which will obviously interdict any llcc development there...the posted llcc is obviously exposed and west of midlevel and convection..isn't the blow up an interaction of the midlevel and this upper air feature which nobody seems to be factoring into equation?...by the way it was there yesterday too, only in a trough, which is what inhanced the sw-ne shear over the feature...

TROPICAL DEPRESSION ELEVEN CENTER NEAR 21.6N 88.9W AT 15/1500 UTC

MOVING NW 5 KT. MAXIMUM SUSTAINED WIND SPEED 30 KT GUSTS 40 KT.

ESTIMATED MINIMUM CENTRAL PRESSURE 1004 MB. SEE LATEST NHC ADVISORY

UNDER AFOS/WMO HEADERS MIATCMAT1/WTNT21 KNHC FOR MORE DETAILS. DATA

FROM A RECONNAISSANCE PLANE...SURFACE AND UPPER AIR OBSERVATIONS

FROM THE YUCATAN PENINSULA INDICATE THAT THE SURFACE CENTER OF THE

DEPRESSION IS STILL OVER LAND BUT READY TO MOVE OFFSHORE JUST TO THE

NORTHEAST OF MERIDA. ONCE OFFSHORE...OVER THE VERY WARM WATERS OF

THE GULF OF MEXICO...INTENSIFICATION IS LIKELY. CURRENTLY...

NUMEROUS STRONG CONVECTION IS NOTED JUST EAST OF CENTER FROM 20N-22N

BETWEEN 85W-87W. BROKEN/OVERCAST HIGH CLOUDS FLOW ANTICYCLONICALLY

AWAY FROM SYSTEM OVER PORTIONS OF THE SOUTHEASTERN GULF OF MEXICO

AND ACROSS THE STATE OF FLORIDA FROM 22N-27N BETWEEN 76W-88W.





TROPICAL UPDATE (#30)

Hello All,
The TWC update stated that TD#11 is reforming to the NE of the previous position. Satellite shows this as well. Over the past couple of hours I have had bands of rain move in from the gulf. As the rains increased winds increased to 20-25 mph and as the rain ended winds died so even though its still far away I believe the outer moisture is getting into my area. I had 1.65" in about 75 minutes. The next 12 hours are going to be fun. Any one pulling there hair out yet!!


My interpretation from Dr. Lyons.... (#31)
Posted by: Teresa Location: Mobile, AL
Posted On 02:10PM 15-Sep-2000 with id (RTNTNRUSNXX*)


He said the activity to the east of the Yucantan is just rain. The LLCC still exist and will continue to move NW as will the rest of the showers. I didn't hear the Dr say anything about reforming. The flare up to me is TD is about to intensify.

Great comments...only, I don't understand what you are saying..lol...could you state that in laymen's terms? Thanks

also: Kristinn Dodd just mentioned that they have crews stationed in Galveston, Mobile (I think) and Tampa...my question is this: where is Jim Cantore...if he's in Tampa, it's a sure bet that't where it will come...wherever Jim goes, the storm follows!!!

He did say their thinking is that the LLCC is trying to reform...they have said that now since 1:30pm....maybe you just missed it...Colleen

I agree with Colleen!! (#34)

You hit the button. Forget looking at sat. loops, start looking for Jim!!

LLC (#35)
Posted by: mike Location: Clearwater Beach
Posted On 02:23PM 15-Sep-2000 with id (RTNQVQNRTPNRPS*)


It is very clear to me that the LLC is moving more towards the midlevel than the mid level is moving towards the LLc. Check your coordinates over last 24 hours.

Rain/Rain (#36)

Posted On 02:32PM 15-Sep-2000 with id (RTNQVQNRTPNRPS*)


Even if this thing doesn't develop it sure looks like the West Coast of florida will get hammered with rain. We are in a rainfall deficit but I would hate to see how much this thing would dump, especially with how slow it is moving. GOT FLOOD INSURANCE?

SHEAR (#37)
Posted by:
LONNY Location: HOLLYWOOD
Posted On 02:37PM 15-Sep-2000 with id (QURNQVSNQYTNRQR*)


The reason it became so elongated is because of upper level shear out of the Southwest. If it survives long enough and enters the warm Gulf the shear is suppose to subside and then it could explode. In the mean time, I think we are going to see an up and down system. I remember some storms having 70mph winds without a complete closed low due to shearing. This could happen to the future Gordon.Until the upper low moves out it won't get it's act together. Not meaning it won't strengthen, just won't have a complete closed surface low.

Funnel Cloud (#38)
Posted by: mike Location: Clearwater Beach
Posted On 02:44PM 15-Sep-2000 with id (RTNQVQNRTPNRPS*)


FYI. Just saw a banner running on the TWC that said a funnel cloud was spotted over St.Petersburg/Clearwater airport. I checked satellite and it looks like a feeder band that caused it. Even if this storm doesn't intensify everbody needs to be careful for the potential for lots of rain and possible tornados.

a new LLC. Finally!! We all know it will become a hurricane, BUT the big question, where is soon to be announced Gordon going?

Tampa Bay Discussion (#40)

Posted On 03:04PM 15-Sep-2000 with id (VSNWSNRQSNU*)


This is very interesting...

VERY COMPLICATED FORECAST FOR THIS WEEKEND...ESP CONSIDERING SATL
EVOLUTION OF TD 11 DURING THE PAST 6 HOURS COMBINED WITH THE LATEST
MODEL RUNS...WHICH ALL ARE SHOWING MORE OF AN EASTWARD COMPONENT TO
THE MOTION OF THE SYSTEM.

It is starting to look like Florida is back in the crosshairs, although this discussion goes on to mention that the system may get sheared out of existence and just bring rainfall to Florida (TBW already predicting up to 4" by Saturday night).

Convertion near the Center (#41)
Posted by: Tom
Posted On 03:28PM 15-Sep-2000 with id (QSRNRRXNWPNQX*)


Looking at the latest IR, it looks like a deep ball of convertion is starting to fire up at the tip of the Yucantan close to where I think the center is re-forming.

Agreed (#42)
Posted by: clyde w. Location: orlando
Posted On 03:41PM 15-Sep-2000 with id (VSNWSNRQSNU*)


Looked at the NRL site and it does look like a new center is forming off the NE tip of the Yucatan. I don't have any idea how this affects the forecast track or intensity possibilities but as a Florida resident I am definitely becoming more interested in this system. I believe we may have Gordon at 5:00 as well.
