Looks like they moved that forecast track a little more northward from the 5pm advisory. I am still concerned about the rain event for the state more than I am the wind; of course, this could change in the next 48 hours. Polk county doesn't need any more rain than it already has.
Time will tell. Looks like it's slowing down and starting to get its act together.

Ok, TD12...

The system has definately taken on a strong Comma appearence - that would seem to be Dvorak 1.5+, with SSD is saying 2.0 about an hour ago. The IR signature is definately getting its act together - less of a blob and more of a tightly defined Comma shape.

Models are still divergent - we'll have to wait for the overnight runs with the TD data input. Right now most of the models were run long enough ago that they were using Tropical Wave data, which is much harder to forcast tracks for. This is especially important becuase GFS seems to be giving an erroneous Atlantic track...so we really need to wait for the NOGAPS, CMC, and UKMET models.

The 11pm intensity chart table gives the storm a 35% chance of being hurricane strength guesstimated around landfall time (48 hours). As stated in the 11pm TD12 discussion at NHC, "THE GFDL STILL DOES NOT EVEN FORECAST STRENGTHENING TO A TROPICAL STORM. HOWEVER... THE SHIPS MODEL STILL INSISTS ON HURRICANE INTENSITY BY 48 HOURS BEFORE THE SYSTEM CROSSES FLORIDA..."

--RC
The rest of the paragraph...
HOWEVER... THE SHIPS MODEL STILL INSISTS ON
HURRICANE INTENSITY BY 48 HOURS BEFORE THE SYSTEM CROSSES
FLORIDA... WITHIN AN ENVIRONMENT OF MODEST WIND SHEAR AND OVER VERY
WARM SSTS. AS MORE OF A COMPROMISE BETWEEN THESE SOLUTIONS... BUT
STILL LEANING TOWARD THE SHIPS... THE OFFICIAL FORECAST IS JUST A
LITTLE MORE CONSERVATIVE THAN THE PREVIOUS ADVISORY... BUT STILL
CALLS FOR A STRONG TROPICAL STORM TO APPROACH FLORIDA WITHIN THE
NEXT COUPLE OF DAYS.

Had to turn on registered user only for replies tonight. Unfortunately. The watches arent' too surprising. The intensity will be the wildcard, tomorrow should be interesting for sure.

Continuing from my previous post

Reading through more of the TD12 Discussion at the NHC:

GFL is the biggest outlier it seems, both in track and intensity. It fails to bring the storm to a TS at all, then it stalls the system over FL. Every other model, according to the NHC, takes it across FL. With ships showing TS by tomorrow and Hurricane before landfall, this could definately be interesting.

NHC is saying the band of convection has formed on the east side of the center - if that is the case then I'm not seeing any convection north, west, or south on IR. I wonder if the center may be realigning itself below the new convection soon?

should make for an interesting thursday/friday. The track is expected more south from where I am (Vero Beach) but as the (volunteer) Red Cross Disaster Services Chair, it will be a very long couple of days. By tomorrow morning we'll probably activate our disaster plan and wait to see if the counties decide to open any shelters.

Here's to hoping for a "non-event"!

I've posted a full, long update to the blogs. I'm further east and weaker than the other pros on here and have outlined why in the update. No real update to 97L's status other than what was posted last night and edited this afternoon, as TD 12 is the big game in town right now. As always, if you have any questions or comments, please feel free to let me know.

I see by the lock down on replies the childern have not been playing well I guess.
The track on TD12 going to be interesting, if she stays weak may just track to W-NW all the way to the gulf with no land fall in FL except maybe the Keys..

the mets I just watched at 11:00 are saying it can make landfall anywhere from Cape Canaveral to Miami. If you are in Vero, aren't you under a warning? Just curious. I don't think we will have a clue what path it will take until morning possibly.

Great update Clark very informative. It helps someone like me that is new to storm tracking to better understand the reasoning for the forcasted path

Debbie:

Remember if you are in the area of the forecast cone then subject to a possible land fall. Don't folllow the thin line folow the cone.

Anyway i just want it to go fast as to sit over the state would be bad for everyone.

Oh I don't Dave, both Frances and Jeanne made landfall here and I am a nervous wreck. I am fascinated with the storms but I also know the damage they can cause.

Re: Tropical Depression 12 Forms Near the Bahamas, Tropical Storm Watches up Vero South [Re: MikeC]
      #48933 - Wed Aug 24 2005 12:25 AM

This reminds me a little of Hurricane Erin in 1995. Going to be interesting for South/Central Florida and the Gulf Coast. Question is how strong it will be when it hits Florida and how fast will it develop in the Gulf?

--------------------
Direct Hits:
Hurricane Erin (1995) 100 mph
Hurricane Opal (1995) 115 mph
Hurricane Ivan (2004) 130 mph
Hurricane Dennis (2005) 120 mph

Dave I have a question, when this storm makes landfall will it lose intensity like Frances and Jeanne,and then if it goes across into the Gulf reintensify? Or does it depend on how long it moves across land?

Or anyone that can answer

once it gets into the gulf it most likely will start to get stronger but how fast it goes once it gets there will make the difference in how strong it gets before a second landfall.

Now all this is IF the track as of now holds 5 days out.

speaking of watches and warning, i like what NHC doing by publicly showing the breakpoints...

ATTN...WFO...MFL...EYW...MLB...


in other words this will help with showing where watches and warnings are at...If you have the product to view them......so the local NWS offices and tv stations weather offices should have up todate information quicker........hey they give the lat/long. of these areas in the text.....should work great with the NWS VTEC.... more info HERE


Well, looks like i will have to deal with another system in a few days....i know i am prepared, beacuse of all the "practice/near" misses we have had here in PCB.....i don't think this will be the last for me this year neither....
I have a bad feeling about September......
