Environment Canada has issued a Snowfall WARNING for the Pincher Creek, Waterton Park, and Crowsnest Pass areas. The warning now includes Claresholm, Fort Macleod, Cardston, and Stavely areas.
Snowfall with total amounts of 10 to 25 cm is expected.
A southward moving cold front will initially produce mixed precipitation in the form of rain and snow along the eastern slopes of the Rocky Mountains and within the Mountain Parks, but should quickly transition over to snow. Snowfall amounts will be highly variable, with areas at higher elevations possibly seeing upwards of 25 cm by the time the snow comes to an end Tuesday evening. For areas just east of the foothills, including the City of Calgary, snowfall totals will be around 10 cm.
Because of the instability along this cold front, this snowfall warning may need to be expanded.
