Mississippi Sound/Lake Borgne is such a vulnerable storm surge area and this storm is going to be moving pretty slow and have a constant flow into that area. This is going to wreck Neck’s camp and fishing spot.

The rainfall projections have gone down a bit but they’ve also put more rain over land too. A mixed bag so far.

They’re going to be seeing constant pressure from the wind for the next 3-4 days.

The rainfall totals are much different from yesterday. They were like 20+ easy east of it.

Anyone remember Barry last year? We got lucky on that one as far as rain went because the models were showing huge downpour on SELA.

Also, they never said the storm surge would be that high in LC. The peak surge is at the coast, and it was indeed 15-20'.

Pretty accurate forecast I think.

Yeah, with the current slight westward shift, what does this mean for BR?

Kind of. The discussion mentions it will be stronger between forecast points so it implies just at Cat 2. Pretty academic though in terms of impacts for most of us.

Modeled rainfall projections can be a bit flaky. Substantial errors on both the high and low end.

The high end potential is certainly a threat due to slow forward speed.

I hate to break it to y’all, but we can handle a CAT 1 in Baton Rouge just fine. Let that bitch track west and leave Lake Borgne alone!

That latest NHC prediction shows a pretty decent stall between 8AM Tuesday and 8PM Tuesday.

If the current forecast holds, what wind speeds are we looking at in Washington and Northern St. Tammany Parishes?

I would start cutting down those pine trees next to your house up that way.

My house can handle a cat 1. It's the big arse cypress in the backyard with 3 days of rain that I'd be worried about.

I think you more need to be worried about tornados spinning up during the apparently 24 hours it will take it to move through
