If Hurricane Wilma hits Florida this weekend as predicted, it could result in many deaths and a tremendous storm surge, the nation's chief hurricane forecaster said Wednesday.
Officials ordered nonresidents in the Florida Keys to evacuate in advance of the storm -- which as of 5 p.m. ET was a dangerous Category 5 hurricane off Mexico.
"We had well over a thousand lives lost in Katrina," said Max Mayfield, director of the National Hurricane Center in Miami.
