Hurricane Milton is back down to a Category 4 storm—after fluctuating between Categories 4 and 5—and is moving across the Gulf of Mexico toward Florida, where millions have been told to evacuate as forecasters warn it could be be “one of the most destructive hurricanes on record” for the west-central part of the state.

Another monster hurricane is set to strike the U.S. just two weeks after the last one. Hurricane Milton rapidly intensified to Category 5 strength on Monday, less than two days after it formed as a tropical storm over the Gulf of Mexico,

The storm is forecast to make landfall in Florida late Wednesday night as a "dangerous major hurricane," according to the National Hurricane Center.
