Can't argue that....

if the storm is large enuf in diamater and landfall to your west i think you will have a potential surge concern. i would be prepared to board up since you live so close to water and since there is a potential hurricane modeled to head in your general direction, worried no , prepared to board yes

It sure does look that way to me at the moment, the fact it does seem to have amassed into one convective mass is a sure sign that strengthening is going on IMO. I suspect recon will find a pressure sub 1000mbs this time round.

Isaac is behaving a lot like a large "stripped hurricane" in the Bay of Campeche after it'd traveled across the Yucatan and lost its middle, but is now reforming.

What effects would the storm staying 100 miles off the weast coast of FL produce
lets say for the Tampa area-Would they still receive squally weather and a tornadic threat?

Close to SA. Will this impede development or is the location of the "center" over water a more key variable? Isaac appears more blobby (important meteorological term) than he did 06Z today.

How large an area does this storm have the potential to cover as far as size goes?

i wonder if the models underforecast the potency of the 700mb circulation further south.

very interested to see where the real LLC establishes itself, and not just a vortex rotating around a broad center.

thinking recon will see something near 15 N / 66/66.5 by the time it gets there

The small ball of convection appears to be the dominant convection area and does not look like it will rotate around that big blob which looks to be dying off?

yes, for the time being that is the dominant convection, and the coc appears to be sw of it.

If so, this thing is getting somewhat better organized

I don't think any of them forecast a decoupled system in the first place.

(The suddenly slower rate of movement will throw the timing of trough interaction & recurvature-or-not going forward.)

That is just a strong cell moving east-to west (not northwest) around the circulation south of it.

(I wish peeps would switch to vis-sat during the day; resolution is so much higher.)

Does appear to have become better organized from all available data I have. recon should find a deepening system

To me the CDO looks to be splitting back into cells again. It may not be weakening but I doubt it is really strengthening much. Maybe later this afternoon after diurnal maximum it will consolidate again. To be honest I'm not sure where the center really is either.

Hello all! I have been looming in the background for several days now just reading and watching... Im a fairly new resident to South Florida and live in southeastern Palm Beach County. Right near the beach

Given the current forcasted track and strength, what if any preperations should I think about making at this point? What type of conditions should I possibly expect?

Again given that the forcasted track doesnt change very much from today..

Thanks!!

The red circle is the location of the mid-level, and dominant, circulation.

True, but if you can run java I think this is the best loop:

http://wwwghcc.msfc.nasa.gov/cgi-bin/ge ... umframes=5

Code: Select all

http://wwwghcc.msfc.nasa.gov/cgi-bin/get-goes?satellite=GOES-E%20HURRICANE&lat=15&lon=-67&info=vis&zoom=1&width=1024&height=768&type=Animation&quality=95&numframes=5


You can adjust location, zoom 1, 2, 4 and number of frames. Usually zoom 1 looks best but Isaac fills the entire frame.
