Live Updates: Ian, now a tropical storm, barreling across Florida

Tropical Storm Ian continued moving east across Florida early Thursday and could still cause "catastrophic flooding," forecasters warned. 

Ian hit land in southwestern Florida as a major Category 4 hurricane, just shy of a Category 5, one of the strongest hurricanes ever to hit the U.S.

It left people trapped in homes and wide swaths of the state without power. Some 2.5 million homes and businesses were in the dark as of 5 a.m. EDT, according to poweroutage.us.
