The U.S. federal emergency agency warned Florida residents not to be complacent about Hurricane Ian, while President Joe Biden has called mayors in three Florida cities in the storm’s path to offer support. He warned Floridians to be ready to evacuate.

Hurricane Ian continued moving toward Florida’s Gulf Coast early Wednesday morning, a day after it strengthened to a Category 3 storm and made landfall in Cuba. Landfall is expected between Wednesday afternoon and early evening somewhere between Port Charlotte and Sarasota, though the hurricane’s track, timing and intensity may change. Florida Gov. Ron DeSantis has declared a state of emergency.

Ian slammed into Cuba on Tuesday, forcing evacuations, cutting power to nearly 1 million people and tearing roofs off homes.
