Storm surges are mainly caused by the strong, circular winds that create hurricanes or tropical storms as they move over the ocean. These winds blow on the ocean surface and transfer some of their energy to the water, creating waves on the surface and in the water columns directly below.
What is storm surge?
The National Oceanic and Atmospheric Administration (NOAA) defines a storm surge as the abnormal rise of water above the normal levels of the tide —meaning that a high tide can make storm surges even worse.
