#1 From around the web:

Gustav has settled into alignment with the other weather systems in the region, and it will probably not deviate from its present track before Gulf Coast landfall. Because it is moving faster than previous projections suggested, it will bring more of its force to the coast.

If landfall occurs near Atchafalaya Bay or further west, the eyewall will pass safely SW of New Orleans. In that case conditions at the city should not severe enough to breach major levees, unless they are weaker than they were before Katrina. But if landfall occurs near Grand Isle, then New Orleans will be hammered by the northeast quadrant of the storm the strongest part.

Yesterday's GFDL model shows category 4 winds blowing water directly into Lake Pontchartrain.

In such a scenario water would flood into the city from the lake, which could drown the city again, and possibly to an even worse degree.

10 PM EDT: New 0000 UTC model runs have clustered on the menacing Grand Isle landfall. Only a few take the storm to SW Louisiana now. The 11 PM NHC advisory will be suitably grave. New Orleans is really at risk now.

Nagin said he expects Gustav to punch holes in the Harvey Canal, which will cause the West Bank to become a bath tub.

The West Bank has 8-foot-high to 10-foot-high protection; Gustavs storm surge may be 15-, to 18- to 24-feet high.

#3 If it gets steered straightoin the path, and goes a bit east, New Orleans is toast.

If it slows a bit, it will fade slighty west, and will weaken a lot quicker, as well as steering the worst of the surge and NE quadrant winds off of New Orleans, probably sparing it.

Both scenarios are possible, neither has been ruled out.

Lets hope the latter scenario is what happens.

#5 Well, there be a reason that area of our continent is shaped the way it is: BIG storms. Hope everyone gets out and doesn't just think it will blow over. Better safe than sorry, as the saying goes.

#7 NOAA National Weather Service office in Slidell, La., which serves New Orleans, issued a statement that explicitly described the impending catastrophic damage expected from Katrina.

#10 This is perfect opportunity to declare Mother Nature and Lake Ponchatrain the winners and make it a PERMANENT evacuation order.

#12 Closest approach is 50 nm southwest of NOLA, coming in over Terrebonne Bay at Cocodrie. The track hasn't changed appreciably in the last six hours.

#13 Gromky, I'd like to point out that with that Katrina warning, at least for New Orleans, most of that DIDN'T HAPPEN.

Many buildings sustained only minor wind damage only to be rendered unfit for habitation by the flooding.

#14 Here's hoping Glenmore and the rest of the 'burgians in the danger zone have found safe shelter or are almost there. Take care, guys.

#15 Blondie, I ain't worried, this isn't even a new storm coming ashore here. It's just a rerun of Andrew.

#16 Katrina weakened to a Cat 3 and passed by NOLA 25 nm to the east. New Orleans wasn't in the dangerous semicircle and didn't get all that much wind, maybe 90 kt. Think Gulfport and Biloxi, which were in a similar position to Katrina that New Orleans is to Gustav, though more exposed. The best hope is that Gustav will weaken and not move to the east of the track it's been holding. At the time the above statement was made, Katrina was a 150 kt Cat 5. Luckily, she weakened, and we can hope for the same.

#17 Andrew hit Louisiana at 100 kt and nearly twice as far from NOLA as Gustav's current track. Gustav is still rated as 115 kt at landfall, a very strong Cat 3.

#18 The DOD briefing on Fox News just reported that a RCAF C-17 is being tasked as part of the NORTHCOM response. Our thoughts and prayers go out to all the Americans in the Gulf. Be safe.

#19 Good thing if it stays Cat3, there is a massive difference in storm sure piled up by a long lived 4 versus a short lived 3. ANd they seem to be trending it west, which is even better for NOLA.

#20 National Weather Service office in Slidell, La.,

Grab yur kittuah, small animals might be alarmed sez forcaster in small N. Fla Burg.

Sez gawds are angrified and need panic. Yankees and old farts first to wet pants. Thousands to die, or not, depending on things, pain in the butt for sure tho say locals.

#21 I just watched Jindal doing the pre-storm informational press conference. This guy has his shit together. I am soooo impressed. What an improvement over Blanco

#22 Looking like it will make shore S of Houma.

Hopefully it slides just a little west and doesnt really intensify much more. If it does that, then NOLA is proabaly going to stay unflooded.

Lucky that it got a lot more disorganized over Cuba than was expected.
