Winter Storm WATCH issued for Lethbridge, Taber, Milk River, Claresholm, Cardston, Fort Macleod, Magrath, Waterton, Pincher Creek, Crowsnest Pass areas
A long duration snowfall event starting this evening through Monday is anticipated for parts of southwestern Alberta as a moisture laden Pacific weather system tracks through the area.
There is still uncertainty around snowfall accumulations as warm surface temperatures will melt initial snowfall. There is also uncertainty as to how far east the snowfall with spread. Current indications suggest that by Monday, total accumulations of 15 to 30 cm over portions of southwestern Alberta are possible.
For the extreme southwest corner of the province, upslope flow will enhance snowfall along higher terrain with localized snowfall totals of over 50 cm possible by Monday.
