At least four people have reportedly died since Isaias made landfall as a Category 2 hurricane on Friday, authorities have said, as forecasters warn of flooding and tornado risks as the storm pushes further inland.
Isaias, which has since weakened into a post-tropical cyclone, first hit the city of Destin on Friday evening, bringing 105 mph (around 169 kph) winds as it struck the Florida Panhandle.
