AccuWeather's Melissa Constanzer explains what a seiche is and why it's important to know what causes it to happen.

A seiche is a phenomenon where water in an enclosed or partially enclosed body, such as a lake, oscillates back and forth, often due to strong winds or atmospheric pressure changes. Recently, Lake Superior experienced a seiche that caused water to drain rapidly from bays, leaving boats stranded and water levels fluctuating significantly across the lake.

The event was triggered by severe storms with strong winds, which pushed water to one end of the lake, causing it to slosh back and forth for hours. Seiches have been recorded in other large lakes, such as Lake Erie and Lake Ontario, and can lead to dramatic water level changes that impact boating and safety. Historical incidents, like the 1844 Lake Erie seiche, have resulted in significant damage and loss of life.
