Storm Surge

Storm Surge

Along the coast, storm surge is often the greatest threat to life and property from a hurricane. The size of a storm surge for a particular location depends on a number of factors. Storm surge is very sensitive to the shape of the coast, and to changes in storm track, intensity, forward speed, and size. Tidal height at the time of maximum storm surge is an important factor.
