Hurricane Wilma has weakened slightly, but forecasters say the Category Four storm could still get stronger again.
Some forecasts showed Wilma hitting southwestern Florida as soon as Sunday, and authorities along the coast of the region said they were monitoring the storm closely.
Wilma is still southeast of Mexico's Cozumel and heading west-northwest at eight miles per hour. It's expected to turn and head for Florida, where it could hit by Saturday.
Winds are currently around 150-miles-per-hour. Wilma has been blamed for at least 13 deaths in the Caribbean. Much of Mexico's Yucatan Peninsula remains under a hurricane warning.
President Bush has urged residents along Florida's eastern coast to take the storm very seriously.
