Introduction Along the coast, storm surge is often the greatest threat to life and property from a hurricane. In the past, large death tolls have resulted from the rise of the ocean associated with many of the major hurricanes that have made landfall. Hurricane Katrina is a prime example of the damage and devastation that can be caused by surge. At least persons lost their lives during Katrina and many of those deaths occurred directly, or indirectly, as a result of storm surge. Storm Surge vs. Storm Tide Storm surge is an abnormal rise of water generated by a storm, over and above the predicted astronomical tides. Storm surge should not be confused with storm tide, which is defined as the water level rise due to the combination of storm surge and the astronomical tide.

September 9, The biggest threat to human life during a hurricane is often the storm surge, which occurs when sea level rises dramatically during a storm, sending a wall of water gushing over land. Forecasters warn that the storm surge from Hurricane Irma could reach 15 feet 4. Storm surge does not come from rainfall or flooding, but occurs when powerful winds from a hurricane push ocean water higher than usual over the shore. Storm surge is an "abnormal rise of water generated by a storm, over and above the predicted astronomical tides," according to the National Oceanic and Atmospheric Administration NOAA. Storm surge begins before the hurricane makes landfall, making it harder for people to evacuate in time.

Forecasters warn that the storm surge from Hurricane Irma could reach 15 feet ( meters) along parts of the Florida coast in the coming hours.

A storm surge , storm flood , tidal surge or storm tide is a coastal flood or tsunami -like phenomenon of rising water commonly associated with low pressure weather systems such as tropical cyclones and strong extratropical cyclones. Its severity is affected by the shallowness and orientation of the water body relative to storm path, as well as the timing of tides. Most casualties during tropical cyclones occur as the result of storm surges. It is a measure of the rise of water beyond what would be expected by the normal movement related to tides. The two main meteorological factors contributing to a storm surge are a long fetch of winds spiraling inward toward the storm, and a low-pressure-induced dome of water drawn up under and trailing the storm's center. The deadliest storm surge on record was the Bhola cyclone , which killed up to , people in the area of the Bay of Bengal. The low-lying coast of the Bay of Bengal is particularly vulnerable to surges caused by tropical cyclones.

A storm surge is water that is pushed onto shore by a hurricane. It is rarely a "wall of water" as often claimed, but rather a rise of water that can be as rapid as several feet in just a few minutes. This wind-driven water has tremendous power. This means a one-foot deep storm surge can sweep your car off the road, and even a 6-inch surge is difficult to stand in. Compounding the destructive power of the rushing water is the large amount of floating debris that typically accompanies the surge. Trees, pieces of buildings and other debris float on top of the storm surge and act as battering rams that can cave in any buildings unfortunate enough to stand in the way.

We've all seen the intrepid TV weatherman, hanging on to a wind-whipped lamppost for dear life — and, perhaps , for dear ratings — during a hurricane. But as we've probably all heard, it's not the wind that'll get you when a high-category storm heads your way: It's the water. As residents of Florida and the Gulf Coast brace for Hurricane Michael, they'll hear lots about storm surge, a bulge of seawater that accompanies hurricanes. It is, statistically, the biggest culprit when it comes to death and destruction in a hurricane. Though to give credit where credit is due, storm surge is largely the result of high winds pushing the water along. Crashing surf and rising rivers are signs of storm surge, which the National Oceanic and Atmospheric Association defines as the "abnormal rise in seawater level during a storm, measured as the height of the water above the normal predicted astronomical tide.
