How powerful will Milton be?Hurricane Milton became a Category 5 hurricane on Monday, but forecasters say it might lose some of its strength before reaching the coast.

In addition to flooding rain and winds topping 100 mph, the storm surge could reach 8-12 feet in the Tampa Bay region, forecasters say. Such a storm surge would cause significant flooding in downtown Tampa. In preparation for the storm, Florida Gov. Ron DeSantis suspended tolls on interstates in affected areas to assist evacuations.
