ATL: ISAAC - Post-Tropical - Discussion

[Elizabeth]

OMG! Did I just wake up to this thing being almost in the same place/same strength it was at 1am!?!?!?!

Im on the North Shore. We have been getting pounded all night but holding up well.

Poor people in New Orleans and Especially Grand Ilse!! That place is virtually just a sand bar!

Prayers to everyone.

BBC News just said that Isaac was a powerful category one hurricane. LOL

[bbadon]

Can someone explain to me how in the hec this thing is going to go anywhere but west?

[Portastorm]

Well, NHC has confirmed what all of us see on satellite/radar ... there is no sustained northwest movement at this time.

In Crowley Louisiana and never got weather like this in the West Midlands before i moved

[Ken711]

Has there been any weakening to the blocking high steering winds to the North to allow a faster move to the NW or NNW?

Can someone explain to me how in the hec this thing is going to go anywhere but west?

I don't know I'm tired of trying to figure it out...they have been saying that since landfall and it hasn't happened yet

[tolakram]

Looks stalled. 15 frame saved loop

[wxwatcher1999]

I don't think it will move NW till at least lake Charles if not further west...that's just my opinion

That is not good news, at all.

[wxwatcher1999]

If anything the last few frames look a little south of west but not really moving at all

[CYCLONE MIKE]

What worries me is if he can get a little extra movement west and wobble a little south that would put him back completely over water to the west of atchafalaya bay.

[tolakram]

Estimated precip continues to rise.

[bbadon]

Ok I have seen a couple differnet twitter reports of +100 mph gust I would not be surprised if this thing isn't strengthening a little.

Just my opinon not a forecast, not a meterologist, s2k disclaimer etc.

[wxwatcher1999]

What worries me is if he can get a little extra movement west and wobble a little south that would put him back completely over water to the west of atchafalaya bay.

That's what I was thinking it would just take one little wobble to the south and it back over water

Here is a roundup of the latest (and maybe last) recon obs. Pressure only up 1 millibar.

From the recon thread.

Here's that 1 minute flash floater: http://www.ssec.wisc.edu/~rabin/goes14/loop_srso.html

Convection fires over water, then dies out as it hits land, comes around, and does it again. Hopefully the center will move inland soon.
