With Hurricane Wilma stalling over Mexico's Yucatan Peninsula and not expected to roar onto Florida's western coast until Monday, Gov. Jeb Bush urged Floridians to use the pause before the storm's arrival to load up on supplies and prepare a personal disaster plan.

"Today's message is to prepare and stay aware," the governor said.
