There was a meteotsunami off the coast of Massachusetts Tuesday

Severe storm brought heavy rainfall, strong winds, hail and possible tornadoes to New England on Tuesday. It even caused a meteotsunami.

A “meteotsunami” or meteorological tsunami is a tsunami-like wave caused by air-pressure disturbances, such as severe thunderstorms. 

“This kind of tsunami is generated by abrupt changes of atmospheric pressure in the causative storm system, which is a line of thunderstorms that moved over the ocean in this case,” the National Weather Service said Tuesday. “The combination of the air pressure effect on the ocean surface, and the speed at which the pressure disturbance travels, can generate abnormal waves in certain situations.”

Meteotsunamis have been observed to reach heights of six feet or more National Oceanic and Atmospheric Administration says. They have a history of occurring in the Atlantic Ocean, the Great Lakes and other places around the world. 

A meteotsunami was recorded on tidal gauges in Woods Hole, Mass. 

Further south, a meteotsunami was recorded off New Haven, Conn., in the Long Island Sound.
