Milton rapidly strengthened into a Category 4 hurricane Monday on a path toward Florida population centers including Tampa and Orlando, threatening a dangerous storm surge in Tampa Bay and setting the stage for potential mass evacuations less than two weeks after a catastrophic Hurricane Helene swamped the coastline. Milton had maximum sustained winds of 150 mph (240 kph) over the southern Gulf of Mexico, the hurricane center said. Its center could come ashore Wednesday in the Tampa Bay area, and it could remain a hurricane as it moves across central Florida toward the Atlantic Ocean.
