Hurricane Idalia is forecast to make landfall Wednesday morning in Florida's Big Bend area, north of Tampa.
The storm is expected to strengthen further as it nears Florida, possibly becoming a major Category 3 hurricane by Tuesday night.
Walt Disney World Resort, located near Orlando, said that as of Tuesday, its resorts and theme parks are open and "operating under normal conditions."
"We are closely monitoring the path of the projected weather as we continue to prioritize the safety of our Guests and Cast Members," the resort said.
Florida Gov. Ron DeSantis warned Tuesday that the "nasty weather" from Hurricane Idalia will reach the Gulf Coast Tuesday night and he urged residents to implement their action plans immediately.
"We are going to be faced with a major hurricane hitting the state of Florida within the next 24 to 36 hours," he said.
