In the United States, one of the greatest recorded storm surges was generated by Hurricane Katrina on August 29, 2005, which produced a maximum storm surge of more than 28 feet (8.53 m) in southern Mississippi, with a storm surge height of 27.8 feet (8.47 m) in Pass Christian.
In the U.S., the largest storm surge ever recorded occurred during Hurricane Katrina in the area of Pass Christian Mississippi, where the level was increased as it entered several bays, including Bay St. Louis. Combined with wave heights, the storm surge at Biloxi, Mississippi created a high water mark in excess of 30 feet.
Higher storm surge occurs with wide, gently sloping continental shelves, while lower storm surge occurs with narrow, steeply sloping shelves. Areas along the Gulf Coast, especially Louisiana and Mississippi, are particularly vulnerable to storm surge because the ocean floor gradually deepens offshore. Conversely, areas such as the east coast of Florida have a steeper shelf, and storm surge is not as high.

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.
Usually, the largest surges occur in the direction of where the wind is blowing. Due to the rotation of the earth, the surge occurs towards the right side of the hurricane in the northern hemisphere, and towards the left side in the southern hemisphere. A larger storm will also cause a larger surge.

Portions of many important coastal cities and resort areas have thousands of people living on land that is less than 10 feet above sea level. Storm surges can knock down buildings, move trains off of their tracks, carry ships and docks inland, fill subways and do many other types of damage.
