Damaging Water Events – Meteotsunami Vs. Seiche
As many of you recall, a high water event damaged areas around Manistee, Ludington, and Pentwater last year. The event, a meteotsunami, occurred on April 13, 2018.
Pictures from Debbi Maglothin show how much the water came and went at Ludington.
Manistee is still working to get their problems fixed before the busy summer season.
At first, the idea was the water rise and fall was a Seiche. But Bob Dukesherer of the National Weather Service says it actually was a Meteotsunami.
A Seiche is slow moving and slushes the water around, like in a bathtub. A Meteotsunami is smaller and focused from the main line of storms or gravity wave. And a Meteotsunami can create a Seiche.
Lake depth and speed of a storm are keys to creating a Meteotsunami. The good news is the depth of Northern Lake Michigan makes events like this rare.
