Most hurricanes take weeks to develop, but some hit the increasingly warm ocean waters and rapidly develop into monsters within days or even hours.

Milton has rapidly intensified into a category 5 hurricane, the U.S. National Hurricane Center said on Monday. Milton is located about 735 miles (1175 km) southwest of Tampa, Florida, with maximum sustained winds of 160 mph (250 kph),

The storm is expected to produce a devasting surge along Florida’s west coast, which could include the Tampa Bay area. Some decrease in strength is forecast ahead of landfall.
