The powerful thunderstorms that that left a path of destruction and at least 3 dead across the Northeast on Tuesday were so strong they generated a small tsunami off the coast, according to forecasters. Data from buoys off the coast showed small fluctuations in water levels after 8 p.m., which lasted for several hours. Most meteotsunamis are too small to notice, with water levels fluctuating by several inches or a foot above the normal tide, according to the weather agency. In May 2012, a seven-foot wave in Lake Erie near Cleveland swept beachgoers off their feet and swamped boats in harbors, according to the NWS. The weather agency said that conditions for destructive meteotsunamis are most favorable along the East Coast, Gulf of Mexico, and in the Great Lakes.
