Helene made landfall as a Category 4 storm in Florida’s Big Bend, but prompted flash flood emergencies stretching into Appalachia. Now, entering the weekend, more than 3 million remain without power and some parts of western North Carolina are cut off by mudslides and flooding.

Helene has weakened to a post-tropical cyclone and is moving north, bringing what the National Hurricane Center called "catastrophic, historic flooding" over parts of the southern Appalachians. At least 42 deaths across the Southeast have been reported as a result of the storm.
