Storm surge is a dome of water that forms above the sea surface as a hurricane or other tropical cyclone passes. It is caused by the high winds of the storm pushing the water against the coastline. The surge can be as high as 20 feet (6 meters) or more, and can travel inland for several miles.

Storm surge is often the deadliest and most destructive part of a hurricane. It can cause widespread flooding, which can lead to loss of life, property damage, and infrastructure damage. Storm surge can also cause erosion, which can damage or destroy coastal ecosystems.

There are a number of factors that can affect the height of a storm surge, including:

* The strength of the storm

* The size of the storm

* The shape of the coastline

* The presence of offshore sandbars or reefs

* The timing of the storm tide (the highest point of the tide)

Storm surge can be a major threat to coastal areas, and it is important to be aware of the risks and take precautions when a hurricane is approaching.

Here are some things you can do to stay safe from storm surge:

* Stay informed about the latest storm forecast.

* If you are in an evacuation zone, evacuate immediately.

* Move to higher ground if you can.

* Do not drive through flooded areas.

* Be aware of the risk of electrocution from downed power lines.

* Stay indoors and away from windows.

* If you must go outside, wear protective clothing and shoes.

* Be prepared for power outages, flooding, and other disruptions.

By following these tips, you can help to stay safe from storm surge and other hurricane hazards.
