According to the National Weather Service, it’s important to put up hurricane shutters when a hurricane watch is issued. The National Weather Service issues a hurricane watch 48 hours before potential hurricane conditions—including sustained winds of 74 mph or higher—are possible in the area. Keep in mind that the best hurricane shutters (rolling and accordion style shutters) will take less time to secure the property than individual hurricane panels or plywood. All hurricane preparations—including the installation of hurricane shutters—should be complete by the time a hurricane warning is issued.
