What is storm surge?
Storm surge is an abnormally high rise of water resulting from low atmospheric pressure in tropical weather systems.
Storm surge can increase the inundation level in a floodplain by water driven landward by wind. Higher tides at the coast will slow drainage from streams and bayous.
The majority of casualties during hurricanes occur as the result of storm surge. The risk to a specific property as the result of storm surge will depend on proximity to water bodies. Shallow coastlines and bays exposed to maximum wind fetch and velocity will be most affected.
