ATL: ISAAC - Post-Tropical - Discussion

[wjs3]

Another small squall right now, and one heck of a spiral band lined up offshore. If it rotates straight in, it will follow this last set right into NE Lauderdale. Will be close!

[TwisterFanatic]

Nothing about a supposed relocation in the discussion.

Joe Bastardi Tweet (10:39 p.m):

"Radial banding and divergent spread west of high cloud indicates this is popping. Center may reform under convection."

[floridasun78]

here it very windy and getting good rain band by airport of miami

[chaser1]

Why is no one on TV weather talking about the trough that is/was supposed to have such an influence on Isaac's landfall point? Anyone know?

Ok I see it now. When looking at the loop, now I'm wondering how much the midwest high was supposed to dip down. It's still creeping toward the south.

Wow, Key West Radar along with NASA 1KM satellite really leads me to believe that Isaac is once and for all really establishing itself vertically. I would go so far to believe that surface pressures have well dropped into the 98_'s mb. If this is so, than it would not be unusual for forward motion to be mitigated somewhat by the deepening phase it (might) be going through. Had not looked to see, but certainly hope recon is soon to make a pass.

It is obvious on radar and obs the center is reforming to the north...take a look at satellite and you can even see what looks to be a dimple or eye trying to form further north

[brunota2003]

Banding on radar seems to indicate the center may be beginning to reform. The bands closest to the radar (to the west) echoes are only about 2 to 3,000 ft off the ground. Bands moving directly over the radar are even lower. South side starting to moisten up.

Captured this from wunderground about 20 minutes ago - reporting station near where i am. Solid ts winds with slow moving squall line moving up into boca and delray.

Have had gusts to at least t.s. force every hours since 7am today. Periods of sustained t.s. winds scatterd throughout the day, with the longest single duration happening last hour.

[Dean4Storms]

If it doesn't relocate we'll have a badly tilted system that will continue to struggle at deepening much.

[Jag95]

Looks like the NHC nudged the path a little further west to NO. It was on the MS coast, right?

[pwrdog]

Maybe a slug of dry continental air moving into the NW area of the storm ( dew points in the mid 60's near the coast in the panhandle)?? If so see how it responds..

[PTPatrick]

Yeah...maye 20 miles west.

My weekly prediction in the Talkin' Tropics forum, with what I think Isaac will do.

-Andrew92

[SootyTern]

So...if Isaac is not intensifying by much, and he is supposed to be moving farther away from us, why are conditions deteriorating across So Fla now? I'm not in a squall band and the wind has picked up a lot. It is finally tropical storm force.

Each storm has it's own personality and I learn so much from each one (mostly not to assume that the next one will be just like the last one-something for you Katrina veterans to think of; the date probably will be the only thing that is the same) so it keeps me fascinated long past the point when I should be sick of these things by now.

[Ivanhater]

what relocation? where?

radar velocities are showing the center relocating under the deep convection to the north...you can even see an eye forming

[HurricaneBrain]

I'm not seeing this new center.

[deltadog03]

IR and Radar really building NW to N...

this storm's character is entire life has been to generate significant banding convection well to its east. i would not be at all surprised if squally bands continue over portions of the peninsula tomorrow as well.
