Joe B thinks Dennis will continue WNW and pass over the W tip of Cuba or even the Yucatan Channel on its way to LA. He is also concerned about the environment very good for intensification until landfall.

I believe the Middle TX Coast eastward to Pensacola could feel the effects of Dennis due to its large size. We just want a few feederbands to give us rain along the Upper TX Coast.

Rain and nothing more than that is what Texas needs now.

I would be much more confortable right now if all models had a beeline for New Orleans....that way they could change at the last minute. I never wish a a storm on anyone, but after seeing what Cindy did last night, a major hurricane in New Orleans would destroy the city.

Being in the bullseye 4-5 days out is exactly where you want to be if you want to avoid a direct hit.

loon, that brings to mind the little southerly jog, executed by both charley and ivan, which took them around but not over jamaica. ....was a head scratcher...something about the interaction of the convection and the vertical relief of the island....just an aside, that said, i agree that unless we see a more northerly component soon, it will pas south of the island......rich

I just cannot see Dennis going north of Jamaica right now. He would need to start turning. It's either going to be a direct hit or just south IMO.

NAM seems to think that it will go north of it. It predicts that Dennis will start his more northerly component by this evening. Hopefully all poo poo! -that wouldn't be a good thing for Florida, unless where it crosses Cuba could deintensify it a lot!
-but this is the NAM, and can it be trusted?

I looked at the past sat pic and it appeared Dennis is moving just a hair north of west. Are the plots verifying this?
