Isaias weakens to post-tropical cyclone after striking Florida panhandle

Nearly a million people are without power in Florida, Alabama and Georgia as rain and flooding remain a concern

Isaias weakened on Saturday to a post-tropical cyclone after striking Florida's panhandle as a category 2 hurricane the previous night, though it still posed flooding and tornado threats as it moved inland.

More than 868,000 customers were without power across Florida, Alabama and Georgia on early Saturday as those in the path of the storm began the cleanup process, according to PowerOutage.us.
