Communities in southern Alberta could see 10 to 20 centimetres of snow Friday and Saturday, according to Environment Canada.
The agency issued a special weather statement for all areas south of Calgary, forecasting that snow will begin near the U.S.-Canadian border on Friday and spread north through the day.
“The heaviest snow is forecast to occur near and along Highway 1 between Calgary and the Alberta-Saskatchewan border Friday afternoon and evening,” the agency said.
Southern Albertans can also expect winds from the east with gusts of up to 60 km/h, which combined with snow, may cause low visibility, Environment Canada said.
Environment Canada added that because the weather system is on a variable track, it may shift further south, limiting snowfall amounts.
