[windnrain]

guys,
Can you keep posting radars. Due to power outages, I am currently without broadband. I am posting from my sprint mi fi device and from my ATT Atrix phone. I don't have enough bandwidth to load large pages but the radar ya'll have been posting loads fine.

Sit Rep. Winds gusting really hard now. South Lafourche Airport reporting sustained at about 53 with gusts to 71 mph. Not much rain but the wind is howling and only going to get worse. I sure don't want to see a stall but I guess that's what is happening. Any reports or warnings posted near cut off la. would be nice since the national weather service page just don't want to load for me.
Thanks,
Tim

Agreed, please keep posting them.

huricanes always slow down or stall as they move onshore unless they are going more than 20-25 mph, but only for a few hours. From the radar and satellite it really looks like the eastern side of the eye will be over NOLA between 3 and 6AM CDT at the latest. There is nothing in the steering wind strength to suggest a stallout. If there is you need to point it out.

Ok.. I will point it out, please read the last 10 pages of the model thread and you will see what we are talking about....


Also if you can show me any factual data that shows hurricanes actually slow down once they hit the coast....That would be a good read for me. I never knew that...

Based on RADAR its near stationary - aka stalled now.

Can you provide a longer loop than one hour? Then you would know if it is moving much. In one hour, it only goes 6-8 mph so you are not going to see anything spectacular as far as movement. Anyone have a 3 hour loop?

Well Tim, I'm a bit of a techno-peasant when it comes to posting still piccies of the radar, but I can tell you with certainty that there are no current warnings on severe thunderstorms or tornadic activity anywhere in the New Orleans forecast area. All is quiet in that regard.

TWC is speaking to Plaquemines Parish's President and he said that the US Corp of Engineers said that the worst was behind them regarding the storm surge???? It's still coming a shore, right?

No offense to Billy Nungueser, and I didnt hear the interview and have no love for the corps, but he isn't exactly well known for getting all his facts straight....

Snow? Lol

[setxndnfan]

No. It takes 24 hours or more for that to happen. Isaac will be well inland by then.[/quote]


You positive about that? Seems it is doing exactly what the latest models showed.[/quote]

The latest models (and NHC) show it well inland by 1PM tomorrow.[/quote]

I am not going to argue as I am new around here but the NHC did not show a stall are a wsw motion like the Nam and others have. That is exactly what APPEARS to be happening now. If it is going to be well inland by 1pm it better turn around and hit the gas considering how far it moved over the course of the last 18 hours.

Can anyone tell me where to find those cool wind field maps that are made occasionally? I guess they are called the wind field analysis or something like that.

Latest radar images. saved.



Radar estimated precip totals



And your forecast, thanks to Accuweather

[stormreader]

Guess I better check another radar loop, cause when you look at this image you almost get the illusion that Isaac has actually made some headway in his westerly drift. Almost looks like he's well west of the mouth of the river now and over toward Grand Isle. Like I said, I better check another radar loop.

I'd take a picture of that Accuweather forecast. Currently snowing in New Orleans with an air temperature of 79F and a hurricane. I told you New Orleans had it all.

Posted this earlier but the board is moving so fast many of you may have missed it. This is a screen shot from a site I found today. Its called SimuAwips. You can create you own account to use it. It is Free. I am in no way associated with the site, just letting you guys know its out there. So far its been fantastic. I've been running a 6 hr KLIX radar animation and you can do up to 12 hrs. But it does many other things and does them pretty good.

Is this what you're asking for?

GRLevel 3 showing a very intense band getting ready to slam toward Grand Isle again in the next fifteen to thirty minutes.

Billy Nungesser the Plaquemines Parish President reported on WWLTV that his house was moving and part of his roof was ripped off. He claimed it was very similar to Katrina, at least with the damage going on around him. Another couple got scared and had to move to a shelter after there house started tilting over.

I forget but are you a meteorologist? You really need to get blue if you are. So your thoughts are that he will move toward the NHC path?

Lol, I really do. I plan to within the next few weeks. There's nothing in the data that suggest anything different. It's on target. It has slowed and is crawling at times now but still looks to me like it's on track. I can't tell you how many of these I've seen slow down for 3 or 4 hours at landfall and often even doen a small loop but then continued on. It is the result of the inner core encountering friction (as ronjon mentioned earlier.)
