It looks to have weakened slightly... my guess is the winds stay the same, maybe a 1mb drop in pressure.

I think they are saying that the hurricane may of peaked. The rapid intensification phase seems to be ending.

I don't think so. It's peaked right now. The CDO structure is a little ragged and the eye is cooling some. I believe it's peaked. It will probably weaken some before landfall...but probably not much.

I wonder if this northward movement was predicted and factored into the landfall models?

Agreed - he's really starting to feel some dry air from the SW - the ULL is feeding him that stuff and he's not going to like it much.

BUT, I'd still prepare for a cat4 landfall.
