Sudden mild weather causes thaw, leaving huge ice chunks on Ontario river


Massive ice chunks from an ice jam washed up on a Canadian riverbank after a sudden mild weather shift after the polar vortex, in West Montrose Ontario, Canada yesterday (February 5).

Footage from the town and riverbank shows slabs of ice nearly a foot thick stacked up as they were moved or washed ashore, as the previously frozen river's surface broke up during the sudden mild turn of weather.
