Yep, NOLA is starting to get some storm surge(not huge) and rain from the outer bands of the hurricane. Don't know if landfall will move all the way east to Port A. and W. LA, it could still wobble and come in at Galveston or even further west. The models are splitting even farther apart, not converging.

And a stall close to or after landfall could throw everything off.
We are already getting outer bands...and I'm South of Baton Rouge.
Great stuff, Diddle! Thank you.
