Storm surge refers to the "dome" of ocean water propelled by the winds and low barometric pressure of a hurricane.
Storm surge from hurricanes have been known to destroy large buildings and communities close to the coastline.
In addition, storm surge from a strong hurricane would not be limited to waterfront properties and could conceivably push miles inland in some areas.

The greatest potential for loss of life related to a hurricane is from the storm surge!
Storm surge is simply water that is pushed toward the shore by the force of the winds swirling around the storm.
This advancing surge combines with the normal tides to create the hurricane storm tide, which can increase the mean water level to heights impacting roads, homes and other critical infrastructure.

  Long Island Storm Surge Maps
urricane storm surge causes approximately 90% of all storm deaths and injuries and much of the damage, therefore it is important for residents of Long Island, New York to be aware of the areas that will be affected by the storm surge.
The southern shore of Long Island is most vulnerable to storm surge inundation because hurricane landfall will first occur there and the low elevation will allow sea water to move well inland.
he height of maximum storm surge is a function of storm strength, location of eye landfall, tidal time of landfall, elevation, and speed of storm.

  weather.com - Storm Encyclopedia -
Although the storm surge is perhaps the most dangerous and destructive part of a hurricane, the winds and the heavy rains can be felt well inland from a storm's landfall.
As the storm moves inland, and is down graded to a tropical depression, the continued circulation, tropical moisture, and topography can contribute to copious amounts of rainfall.
The storm surge is a rapid rise in the level of the water that moves onto land as the eye of the storm makes landfall.

When this shoved water, or storm surge, reaches shore it is often called a "storm tide" or "tidal wave," though it has no more connection with gravitational tide than does a tsunami.
Storm surges are enhanced by the extremely low atmospheric pressure that accompanies tropical cyclones.
The low pressure at the center of the storm causes the water beneath it to rise in a "hump" that floods inland as the storm strikes a coast.

  Chapter 02 STORM SURGE
Storm surge is the increase in height of the surface of the sea due to the forces of an approaching hurricane.
The meteorological parameters affecting the amount of storm surge generated include the intensity of the hurricane measured by the central barometric pressure and maximum surface winds at the center of the storm, path or forward track of the storm, forward speed, and radius of maximum winds (storm size).
The location of the peak surge depends on where the eye of a hurricane crosses the coastline, its intensity, the bathymetry and topography of the basin, configuration of the coastline, the approach direction, and the size or radius of maximum winds of the hurricane.

 Hurricanes and the U.S. Gulf Coast: Storm Surge and Flooding
Storm surge is determined primarily by meteorological forcing (storm intensity, path, and spatial and temporal scales) and topographic parameters (width and slope of the continental shelf, geometry and character of local coastal and shelf features such as barrier islands, headlands, bays, sounds, inlets, marshes, channels, levees, and barriers).
Storm surge estimates in the 1950s and 1960s were obtained assuming a steady force balance between the onshore wind stress, the water surface slope, and bottom friction.
Finally, interactions between storm surge and wind wave models are being pursued to allow inclusion of the water surface setup due to gradients in the radiation stress associated with wave breaking, the influence of wave conditions on the air-water drag, and the influence of waves on bottom friction.

The prediction of storm surge resulting from the combined meteorologic, oceanic and astronomic effects coincident with the arrival of a hurricane at the coast is a very important problem, but rather a difficult one to solve.
The hurricane surge estimated by this simple model is a composite of water elevation obtained from components of the astronomical tide, the atmospheric pressure, the initial rise, the rises due to wind and bottom friction stresses, and wave setup.
The prediction of storm surge resulting from the combined meteorologic, oceanic, and astronomic effects coincident with the arrival of a hurricane at the coast is important in warning the public and in the planning and the design of important coastal structures.

 The Weather Doctor Almanac 2004
Storm surge is a very complex component of a strong storm over water, though in simplest terms, it is water pushed toward the shore by the wind forces of a storm.
However, we now know that the major storm factor defining the surge height is the resultant wind speed of the storm, the combination of the mean wind speed and the storm speed, which is generally greatest in the fore-right sector of the storm, usually the northeast sector, determined by its direction of motion.
Among the topographical factors influencing the storm surge are the slope of the sea bottom offshore, the slope of the shoreline itself, and the nature of the shoreline shape — that is, the orientation and size of indentations such as bays and estuaries — and offshore islands or barriers.

 EO Library: Hurricanes Page 3
Storms in the Atlantic may go through a natural cycle of 20-30 years of increased activity followed by a quieter period.
Further, satellite technology and the methods used to estimate a storm’s intensity have improved, so a storm that may have been classified a Category 1 or 2 in the 1970s through the mid-1980s would be classified as a much stronger storm today.
From those measurements, wind speeds at the center of the storm and thus the storm’s intensity were estimated.

 Weather: Shrinking core reduced storm surge
Storm surge is saltwater flooding that rushes over coastal areas, near where the eye comes ashore.
Since they didn't know precisely where the storm was going to hit, forecasters ran a variety of scenarios, including the worst case, which had the storm's strongest winds pummeling the heavily populated Tampa Bay area and churning up a devastating surge.
Although the storm packed winds up to 144 mph, its main impact came from storm surge and breaking waves that flooded the coast with 10 to 20 feet of water, according to the hurricane center.

 Storm Surge: a concern to coastal residents
Storm surge is the rising of the sea level due to the low pressure, high winds, and high waves associated with a hurricane as it makes landfall.
Ocean waves also contribute to the overall storm surge as the waves which may only be a couple of meters out at sea grow as the ocean depth decreases to several meters at the shore.
Typical storm surge heights vary with the hurricane's intensity, but they can range from only 1 to more than 5 meters (3 to 25+ feet).

 Hurricane Evacuation Zone Maps-Frequently Asked Questions (FAQ)
It is important to note that storm surge maps reflect the worst case hurricane storm surge inundation (including astronomical high tide), regardless of the point of where the center of the hurricane (or tropical storm) makes landfall.
However, the level of surge in a particular area, when all other factors are held constant, is in large part determined by the slope of the continental shelf.
The storm surge maps for Mississippi and Alabama coastal counties were developed by overlaying the water surface grid from the SLOSH model on a ground elevation grid made from U.S. Geological Survey (USGS) 7.5 minute Digital Elevation Models (DEM) and determining which ground cells were flooded.
