After pummeling the Florida Keys, Irma was degraded to a still-extremely-powerful Category 3 storm as it made full contact with the Florida mainland. Landfall was at 3:35 local time, at Marco Island; gusts in nearby Naples reached 142 miles per hour. Since landfall Irma has been downgraded to Category 2; the majority of the state is under a tornado watch.
As the storm now approaches Tampa, the most immediate danger is for coastal communities on Florida's western coast, where storm surge of up to 15 feet is expected to follow closely behind the eye. Naples and Marco Island are expected to be hit the hardest, with extensive potential flooding in the Tampa area as well.
Irma continues to be a massive storm; though it came ashore on the western side of the Florida peninsula, on the eastern side Miami has also been subjected to winds over 100 miles per hour. Those winds caused the collapse of at least two large construction cranes; storm surge flooded low-lying streets.
Ft. Myers is currently recording gusts over 80 miles per hour. Irma has left two million customers without power so far; this number, too, is expected to rise. Evening curfews are in effect for many counties in Irma's path.
