On the overall trend of things, it is significant that the Yucatan coast now has a TS warning and hurricane watch! Not too many of us expected Ivan to move as far south of Grand Cayman as it did.
I mentioned last night that I didn't expect Ivan to move north of Cuba's latitude for the next 48 hours, and it looks like we might have to wait another 48 hours from this point ... as Mr Stewart is now pointing out. NHC is certainly earning their money this year, particularly with Ivan.
Now that the ridge to the north is breaking down, we can all anticipate a more NW movement with some acceleration after 24 hours. At this point, I'm still living within the 48 hour window ... something that those of us living along the coast (at a latitude above 23) need to get used to.
