End of North Movement?

I see it....there is a high pressure at that location that is still over New Orleans to the West, as well. It's a hot, partly cloudy breezy day, today.

I think it looks like that because of an improving outflow.

<P>Why aren't you stuck in traffic somewhere trying to get out of New Orleans?

I live on the Gentilly ridge which is at sea level. Plus I have a boat in the carport.

When the levee broke during Betsy, we only got enough water in the house to barely cover the carpet.

Okay, stay safe!

I'm staying, as well, FritzPaul---alot are leaving, but, a pretty good amount are staying, as well. I just got back from Sav-A-Center on Tchoupitoulas St. (I live Uptown) and I was in line for 45 minutes and they had every check-out computer working, as well as all of the self check-outs. It was wall to wall people, staying, who were stocking up for the storm...

whos to say he wont squeeze out to the east?...... hmmmmmm

what would keep it from going east?? why would it only go west??

Because the high to the east of him would prevent it. Plus...if he is going to move NW...which I still think he will at some point...it is going to be because the high over LA moves east. That will then block him to the NE and E...which will force a NW motion. He can't move east into the ridge. It's too strong.

Last few frames indicating a possible start to this NW movement, AFM. I've been anxiously awaiting it all day after watching that ridginess build to Ivan's north. Guess we'll find out in a few hours if this WNW/NW motion is more than a minor wobble.

Question: With the high above Ivan and the trough coming in from the East would the storm not take the path of least resistance? ie. more west. Is this what you all are refering to?

[PurdueWx80]

Yes, if enough of a ridge forms to the NNE of Ivan, then the trough in the Rockies will erode the ridge over LA and TX...allowing a more northwesterly movement towards LA rather than MS or AL. I'm not forecasting a strike as far west as New Orleans but as of now I definitely think the MS delta is a target.

[bbadon]

Thank you. A local met here in Lake Charles said there is a remote possibility it could go as far west as the Atchafalaya Basin

[LaBreeze]

I seriously doubt the Basin would get a direct hit. Don't know where that met. got that one.
