To allan from the previous thread...no harm from the NHC in not upgrading sooner. Take it with a grain of salt where the complaints were coming from...there's a reason none of those bloggers work at the NHC.
Mike is right..this far out modeling flip-flopping is par for the course & the immediate threat is to those in the islands...way too early to say what if any impact this will have to the CONUS.
Use this time to finalize any preps..replace the Spaghettios the kids ate over the summer, stock up on gas(if this does threaten the CONUS, especially the Gulf, I dread what gas will shoot up too) and watch & wait.
As a storm weary...especially after '04..Fl native, I look forward to just watching a fish-spinner. The insurance crisis we already face would become unbearable if we endured another direct hit.
