What is storm surge, how does it happen and why should you be wary of it? Here is a quick look at storm surge.
What is storm surge?
A storm surge is water pushed inland as a hurricane advances and makes landfall.
How does it form?
Imagine a bowl of water. Put your hand in the middle of the bowl and cup it. Now slowly push your hand toward the edge of the bowl. Those are the same dynamics as storm surge. The ocean water is pushed by winds and waves, and is also sucked into the air near the eye of the hurricane by low pressure.
Is it a “wall of water” that rushes in?
Rarely. It is usually a rise of water that can happen quickly, moving at the same rate as the forward speed of a hurricane.
How powerful is a storm surge?
Very powerful. Only 1 cubic yard of sea water weighs 1,728 pounds. A 6-inch surge can knock a person down.
