There's a huge blow up on the south side of the circulation that will circle around to the southern parishes within the next hour.

Not one bit of good news from the 06z GFS, don't expect for things to improve much until later tonight, must likely after midnight.

Ndg, can you give a little more detail on gfs like where it's projecting Isaac to be in 12 and 24 hours? Thx.

It shows little by little move WNW to NW, to be only 50 miles or so WSW of Nola later this evening around sunset approaching the Atchafalaya Basin. Go up the basin and be between Alexandria and Lafayette 24 hrs from now, by then your wx should had improve by now, but you have a good 12-18 hrs of this wx to go through, in the Nola area.

I can't post a pic, but about south of morgan city (maybe), in 12 hours, near maybe north of jennings or so in 24 hours. Guys, please correct me if i'm wrong.

The fence between me and one of my neighbors is down. Otherwise can't see too much.

We have been having gusts over 80 for several hours now. Dylan, how is this compared to Gustav?

I'm posting from my phone: I have moderate damage, the third floor apt lost a good portion of its roof and now the water is leaking into my apt. Water coming in from the walls and wall sockets. My neighbor lost his glass doors and another building in my complex also lost its room. This is intense!

Is it possible for a center reformation under the new convection right off shore?

People are going to be shocked by the damage.

That is not going to be pretty when it rotates through.

The rain water came thru the cinder block walls and from around the a/c unit. Woke up in the middle of the night and stepped onto a soggy carpet--yuk!

stormydds: Thanks for your response. I felt that is the case. that's too bad. Has there been any peer reviewed papers on the LRC hypothesis? Nov 4, 2022 14:01:51 GMT -6

Zack Fradella: Not sure, the LRC is something that takes a lot of work to follow and keep up with. It's not as easy as looking at the parameters and making a forecast. This deters many from even giving it a chance. Also, there is some doubt from the weather world. Nov 4, 2022 3:38:49 GMT -6

stormydds: Zack, a friend had a meeting in Lafayette which Rob Perillo spoke.He asked him why the LRC is not used to forecast hurricanes by NOAA.His answer was that Lezak won't share the info.I saw the podcast you and David made with Gary.He seemed open.What gives? Nov 3, 2022 14:39:19 GMT -6
