Detailed explanation-1: -ELEVATE YOUR HOME While it is an investment, elevating your home is one of the most effective ways to mitigate storm surge effects. Elevation may also lower your flood insurance premium. When a home is properly elevated, the lowest floor should be above the BFE.
Detailed explanation-2: -This rise in water level can cause extreme flooding in coastal areas particularly when storm surge coincides with normal high tide, resulting in storm tides reaching up to 20 feet or more in some cases.
Detailed explanation-3: -Storm surge will be higher when a hurricane makes landfall on a concave coastline (curved inward, such as Apalachee Bay in Florida) as opposed to a convex coastline (curved outward, such as the Outer Banks of North Carolina).
Detailed explanation-4: -Storm surge is the abnormal rise in seawater level during a storm, measured as the height of the water above the normal predicted astronomical tide. The surge is caused primarily by a storm’s winds pushing water onshore.
