Rising waters from a Category 4 storm can cut escape routes as early as five hours before landfall, with flooding as much as six miles inland. The coastal storm surge may reach 18 feet, and the winds can rip away roofs and walls of homes, according to the National Hurricane Center. A Category 5 storm can destroy the roofs of industrial buildings, flatten all trees and homes, and drive a storm surge above 18 feet. Only three Category 5 storms, Andrew in 1992, Camille in 1969, and the Labor Day Hurricane of 1935, have made landfall in the U.S. since record-keeping began.
