Hurricane Milton tracker and forecast: Milton rapidly strengthens to Category 5

The St. Pete-Clearwater International Airport, just outside of Tampa, Florida, will close at 12:30 p.m. Tuesday and stay shut on Wednesday and Thursday.

"The airport is in a mandatory evacuation zone and is not a public shelter," airport officials tweeted. "Prepare and stay safe."

Tampa International Airport will suspend operations beginning at 9 a.m. Tuesday and stay closed "until it can assess any damage after the storm," airport officials said.

Milton rapidly intensified to a Category 4 hurricane with 150 mph winds Monday morning.

Within hours, Milton strengthened to a Category 2, then a Category 3 and then a Category 4.

Hurricane Milton is forecast to make landfall Wednesday night or early Thursday morning as a Category 3 hurricane. Landfall is expected anywhere between just north of Tampa to south of Sarasota.

A record-breaking storm surge of 8 to 12 feet is forecast for the storm surge-prone city of Tampa. This comes just after Hurricane Helene brought a record storm surge of 6 to 8 feet to Tampa Bay.

A hurricane watch was issued for Tampa Bay and Fort Myers, while a tropical storm watch is in effect from Apalachicola to Key West.

Water inundation from Fort Myers to Tampa could be higher than the record-breaking 7 feet recorded during Helene.

Flooding is also a threat since a separate storm has dumped rain on Florida for the last several days.

Hurricane Milton early on Monday strengthened to a major Category 3 hurricane, with wind speeds of about 120 mph, the National Hurricane Center said.
