Expect a Storm Surge of 15-20 Feet in a Landfalling Category 4 Storm in the Carolinas
Landfalling Category 4 hurricanes are rare in the mainland U.S., with just 24 such landfalls since 1851—an average of one every seven years. Category 5 landfalls are rarer still, with just three on record. All but three of these 27 landfalls by Cat 4s and Cat 5s have occurred south of South Carolina’s latitude, so Florence will be in very select company if it manages to make landfall at Category 4 strength in North or South Carolina.
