Rochester, New York, US - Wind and thunderstorms are producing some strange occurrences on Lake Ontario.

Residents along the lake have noticed water rushing out away from shore and coming back, similar to tides.

The 13WHAM Weather Authority explains the phenomenon as a "seiche." A seiche occurs in lakes, bays, and harbors, when we see a changes in air pressure and strong winds . This causes the water to be displaced from one portion of a shoreline and resulting in flooding in another location.
