Hurricane Michael's battering waves swamped streets and docks and shrieking winds splintered trees and rooftops. The most powerful hurricane on record to hit Florida's Panhandle left wide destruction and at least one person dead and wasn't nearly finished Thursday as it crossed Georgia toward the Carolinas, still reeling from epic flooding in Hurricane Florence.

Authorities said at least one person has died, a man killed by a tree falling on a Panhandle home. Search and rescue crews were expected to escalate efforts to reach hardest-hit areas and check for anyone trapped or injured in the storm debris.
