Residents of Florida's Gulf Coast headed for higher ground as the hurricane threatens to bring a deadly storm surge and more than a foot of rain to some areas.

The attractions that will be closed on Wednesday and Thursday include Animal Kingdom, Hollywood Studios, Epcot and Magic Kingdom, a spokesperson said.

Walt Disney had earlier said that some of its hotels in the region would be closed through Friday.

Comcast Corp's Universal Resort and SeaWorld Entertainment Inc also announced the closure of their theme parks on Wednesday and Thursday.

About 2.5 million Florida residents were under evacuation orders or warnings with the sprawling storm on track to make landfall as a Category 3 hurricane on Wednesday evening somewhere along the Gulf Coast.
