Dry air continues to plague Issac's development as it speeds to the West. The weaker he stays the more west it will likely go; thus taking the Eastern seabord and the Bahamas out of the picture.

This season storms have not strengthened as expected. Dry air and fast tracks west have inhibited development and most models have erred by showing the storms strengthening more than they actually did.

I think this pattern is continuing with Issac which is a large storm with larger problems in getting its act together.

I see Issac staying weak, almost missing Hispanola while turning WNW and then NW over Pilon Cuba and then Central Cuba and on towards Key West.

Accordingly the GOM from 85 longitude east should stay vigilant and the further west of the Florida peninsula the stronger it could get as it heads NNW.
