CFHC Talkback For News Story #74:
Newest Talkback: 09:16 PM 08-28 EDT

Activity Southeast of Florida
08:36 AM EDT - 28 August 2000

Not much happened over the weekend, but at the start of this week we have a system southeast of Florida that has a chance to develop a little. If it does expect a little wetness around Florida.

Other than this area, there isn't much going on. The wave in the Caribbean is getting sheared to death, and not surprisingly, Debby never came back from the dead.

Depends on how squally the weather is. I'm sure recon will tell more.

At 12:00pm, Buoy #41009 was at 1014.7; as of 1pm, pressure was at 1014.3 and falling.

Buoy 41010 was at 1015.7 at 12pm, at 1:00pm pressure was 1014.9 and falling.

Pressure down to 1013.8 at 2:oopm from 1014.3..if it keeps dropping at this rate, we may have TD#8 by 5 or 11 today. Couldn't get un updated report from Buoy 41010 yet. Did everyone fall alseep? Or I am boring you to death?? LOL!

shear, subsidence, upper trough.. whatever is trying to spin up off florida still has a few hurdles to scale. after the avn and mrf repeatedly predicted debby's westward suicide run (the westward part anyway), theyve gained some immediate credibility to me.. forget what i think, nhc has gone and scheduled a recon. if the upper high does bridge over to the north and stamp out that area of subsidence with the weakening (?) upper trough in north florida.. we could have an interesting week. one of the trademarks of this season so far has been that every storm has had to deal with shear.. given the chaotic upper air state of the north atlantic basin right now, ill have more faith in this wannabe vortex when it stops having shear peel back the edges of the associated convection. until that stops there wont be any ernesto's creeping up on fl/ga/sc. as far back as august 10th or so, though i never posted it, i'd thought there would be SIX named storms this month.. now i dont think that guestimate of mine will verify. two storms in three days, with the atlantic in such a blender.. is a bit much to expect. might get ernesto in the next couple of days though.. take it easy everybody.
TD#8 soon? (#27)

Well the disturbance off east florida looks really good on satellite imagery. there is definite evidence of a cyclonic circulation, and indications that a LLCC is trying to form. Bouy data continues to indicate falling SLP also. NHC are no running 'test' model predictions on this system, and with the recon flight now planned, they must feel it is quite a significant threat. It has got better organised since the last Outlook issued by them at 11:30am, and i would not be surprised to see it upgraded to TD#8 in the 5 or 11 update. But we will just have to wait and see. It appears to have taken a jog to the east, as some of the models indicated, but they also indicate it will then head back west, or north-west, landfalling later in the week somewhere between Central Florida and North Caroline. Will have to wait and see. Meanwhile a Tropical Cyclone Formation Alert remains in effect on my site, which has just been updated.

As Frank said, the system has to defeat the shear monster first. There is subsidence (dry air) also coming down the Peninsula that could inhibit development. In the last few hours, the convection has definitely waned in the western semicircle.

The pressures may be falling, but mostly due to diurnal variation. This time of yr in the Florida latitudes and south, the normal diurnal variation results in the highest pressures around 10 am and 10pm, lowest 4am and 4pm (or thereabouts). If the pressures keep falling throughout the pm, then that will be interesting.

Pressure also falling around the skeletal low off EYW, may also be diurnal.

Finally, the glob in the NW Carib may be a plare after all..stay tuned!

IHS,

Bill

Good point, Bill..we will have to wait and see...however, the pressure at buoy #41009 has now dropped down to 1012.6mb...so it has fallen 2mb in three hours. Something's going on out there, and NHC knows it...they were doing a test run on TD(AL9000) today and had the initial pressure at 1013. Will be interesting to see what happens...remember Debby?

if any with that system. It is going to be hard for it to defeat that North/South Shear with all the dry air that brings in. Not sure if the shear will back down anytime soon. Looks like it has a bit of a circulation. Not sure if it can organize.
Interesting!!! (#31)

Take a look latest radar loop out of Cape Caneveral. It is interesting. Some circulation.
Surface Low (#32)

At 4:00 P.M., Buoy 41010 is reporting a pressure of 29.92 In. or 1013 MB. Buoy 41009 is reporting a pressure of 29.90. Not really significant, considering the SLP here at my house is 29.88 In. If anything develops from this surface low, I suspect it will occur relatively slowly; however, WV imagery indicates a very hostile environment. Strong southwest wind shear will continue for the next 24 to 48 hours as a trough axis over central FL moves eastward. Strong subsidence behind the axis is being pulled down from the NW by an intense cyclone over eastern North Carolina. This subsidence is quickly encroaching upon the surface low east of Cape Canaveral, and IR imagery already indicates a wane in convection, as Bill noted above. This system will have it tough, and right now I'm doubting development.

God Bless,
