What is a meteotsunami?

By Brian Lada, AccuWeather meteorologist and staff writer

When intense storms move over open water, they can generate a wall of water known as a meteotsunami, an uncommon event that can cause damage along the coast of bodies of water.

These events can be difficult to predict and can range from small, almost undetectable waves of water to larger waves that can inundate coastal areas.

“Meteotsunamis have characteristics similar to earthquake-generated tsunamis, but they are caused by air pressure disturbances often associated with fast-moving weather systems,“ the National Weather Service (NWS) said.

A fast-moving line of storms, such as a squall line or derecho, can be strong enough to trigger a meteotsunami in addition to other dangers such as powerful winds and frequent lightning.

We're under a Severe Thunderstorm Watch here in Lansing until midnight, but it looks like that derecho is going to swing south of us. To any and all in the path of that thing, stay safe!
