already a cat 5 Hurricane ... and now this from the National Hurricane Centre this am ...
I'm assuming that we don't have any RJ members in the Turks and Caicos or Puerto Rico ... at this point the trajectory (very preliminary) has it crossing the Florida Keys & turning north towards the Florida panhandle.
