Icy roads led to multiple accidents across North Carolina, South Carolina, Virginia, West Virginia and Pennsylvania from Monday into early Tuesday, while more than 20 inches of snow piled up in western New York.

Interestingly, Olympia was also the one-day snowstorm of record at Ottawa International Airport, Canada, where 51 centimeters (just over 20 inches) of snow fell on February 16, according to Environment Canada. The previous record (40.6 cm or just under 16 inches) at Ottawa's Airport had stood since March 2, 1947.
