Current track has Isaac skimming the spine of Cuba, expected to be a hurricane within 36 hours...with additional intensification expected.

Yeah, there's been a dramatic change in the NHC's forecast overnight: yesterday afternoon, they had it only getting to hurricane force as Issac passed Tampa. But they're still behind even this morning.

Bastardi had a tweet'd track pic last evening suggesting a Cat 2/3 storm as it hit the Keys... now looking like it could do at least that if Cuba is missed all together... he had it slightly west then... now moving more easterly and suggesting 970 mb storm. He will be on Fox News Channel at 11am EDT this morning.

All interests in the Florida Keys: you've got 36 hours to get ready!
