Life-threatening storm surges are expected to hit Florida's Gulf Coast this week with the arrival of Hurricane Milton, which was upgraded Monday afternoon into a Category 5 hurricane over the southern Gulf of Mexico.

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.
