Holi tsunami!!!-------'Great Lakes tidal wave' causes 5-foot immediate rise in water on Lake Superior shoreline

'Great Lakes tidal wave' causes 5-foot immediate rise in water on Lake Superior shoreline | MLive.com:
A seiche, which is the Great Lakes version of a tidal wave, hit the eastern shoreline of Lake Superior near Sault Saint Marie around 6 p.m. Thursday, Sept. 4, 2014.

The seiche (pronounced SAYSH) was caused by a dramatic change in wind direction due to severe thunderstorms. 

The wind was blowing out of the southeast for a long time period, pushing water along the shoreline out into Lake Superior. 

Then a line of strong thunderstorms moved through, and the accompanying west wind blew the water back into shore.

The U.S. Army Corps of Engineers reported a 65-inch change in water levels. 

First the water lowered by 14 inches and then quickly rose 51 inches.
