While a hurricane’s winds and rain are detrimental enough, the storm surge that follows generally causes most of the flood damage. A storm surge is created when a hurricane can be worse than the force of 120-mile-per-hour winds. This is bad news for the 4.2 million residents along the Atlantic and Gulf coasts and the $1.1 trillion of property that is vulnerable to severe flood damage. As if that isn’t bad enough, over half of the U.S.’s economic productivity is along coastal zones. While floods are unpredictable and unpreventable, you can prepare now to reduce resulting damage drives water ashore, and the impact of the waves in the future.
