Dean intensified late Friday to a category four storm, packing fearsome winds of up to 215 kilometers (135 miles) per hour, as it blasted across the Caribbean toward Jamaica.
US space officials are concerned that if the hurricane veers toward the Texas coast, where the Johnson Space Center is located, it could affect the spacecraft's landing.
"We'd really like to protect an option to end the mission on Tuesday," LeRoy Cain, chairman of the mission management team, told reporters.
"The center will have to make a decision in the mid-Sunday to mid-Monday on whether or not to close," he added. "But the decision to land Endeavour early would have to be made well before that."
The shuttle is currently scheduled to return to earth on Wednesday.
