ATL GUSTAV: Tropical Depression - Discussion

[fasterdisaster]

bob rulz, it was Category 4 surge.

How could it have been a category 4 surge if it was never a cat 4 in the Gulf? Isn't a cat 4 surge upwards of 20 feet? This surge isn't that high...

It was 150 mph over Cuba. Cat 4 surge is 13-18 feet and I think some surge was 14 feet from Gustav.

bob rulz, it was Category 4 surge.

How could it have been a category 4 surge if it was never a cat 4 in the Gulf? Isn't a cat 4 surge upwards of 20 feet? This surge isn't that high...

It was 150 mph over Cuba. Cat 4 surge is 13-18 feet and I think some surge was 14 feet from Gustav.

Yeah, but most of the surge was blocked by Cuba from when it was a Cat 4.

[JusLimin]

I'm trying to get info out of Terrebonne too. I'm sure lower Terrebonne got some heft damage but I haven't had anything confirmed except from watching Jim Cantore on TWC.

Look to right side of web page for 'most read' and 'most recent' articles. Some specifics there.

That could be considered upper cat 3 surge for many areas.

I have been having trouble finding standard surge for each category. Does anyone have a link that has that info?

[KWT]

Yep i'm hearing the Plaquemines Parish levee has been breached, I don't think those leevees have been strengthened nearly as much as they had around N.O it seems

As it was said on WDSU, the levee hasn't breached, but is at risk of failing. These conflicting news reports and some lack of information can be confusing.

[KWT]

Yeah I'm watching fox Enzo and they are reporting water is leaking through, what exactly that means and how severe it is I've not got a clue but its never a good sign when that starts to happen.

[funster]

Seems to surge is still rising.

Governor Bobby Jindal said the Corps of Engineers is closing the London Avenue Canal for the first time ever after Lake Pontchartrain continues to rise as Hurricane Gustav marches inland.

The safe water mark is 5 feet at this canal, but the Corps closes the gate at 4 feet. It should take 45 minutes.

There's no such thing as a "Category 4 surge" or a "Category 3 surge". A hurricane's peak wind over a small area is only a very tiny part, an almost insignificant part of the total surge height. Surge should never be tied to a hurricane's peak wind, but to the size of its wind field (in particular, the hurricane force and greater winds), the forward speed and angle of approach, the coastal bathymetry, and any bays/inlets in the path of a hurricane. All of those factors are far more significant than the peak wind (SS Category).

Lost power for 3 hours. It came back on just as we started the generator and were plugging things in. Breinla and i are fine, no damage. Tenspeed had damage to her house.

One fatality here from a tree falling on a house. He was 27. Katc showed a video and it didn't even look like a house was there.

I was quite impressed with Gustav's surge here in Biloxi.. my best guess would be in the 10-11 foot range as it did cover the sea wall and it's 10.5 feet ASL and also completely flooded the south lane of HWY 90.. it's gone down quite a bit but I'd estimate its still a good 4-5 feet ASL due to the brisk 20+ mph southerly wind flow...

[jimguru]

Levee is going over the top near St Bernard Parish - CNN / FOX now reporting - does'nt look good. Looks like they are trying to do their best to stop it....

That is heart breakingly tragic. My thoughts, and prayers, are with his friends and family.

Anybody else heard that Lake Charles may get 20+ (yes twenty) inches of rain?

[scotto]

The winds have calmed down here in Baton Rouge. Lost power at 12:08 and conditions declined from there. I was doing alright till the first 60' oak pushed over and smashed my neighbor's house. Everyone was ok. Highest winds I have ever seen. I can't imagine staying through a larger storm.

The heavy winds came from the NE and several hours later began shifting to the SE, which I was thankful to see. I guess some people might say Gustav was a little one but I think Baton Rouge set a record today for max wind speed during a hurricane.

Gotta put some fuel in the generator.

[Ed Mahmoud]

I don't think so. Shreveport, maybe.

LCH is well South/West of the track. They got some good rain, but areas near the center, especially at night during the core rain event, will get the most. ESF also could get a lot.

[Enzo Aquarius]

Water is no longer overtopping the Braithwaite levee, thank goodness.

Glad to hear you are fine CajunMama. Sorry to hear the bad news.
