The snowfall warning for Calgary has ended but emergency officials are reminding drivers to be careful on the slick roads after southern Alberta woke up Sunday morning to the first snowfall of the season.

Environment Canada ended the Calgary warning at 4:29 p.m. MT Sunday. Warnings in seven other southern Alberta regions have also been lifted.

The weather and road conditions are believed to have claimed two lives after a crash near Three Hills Sunday morning between a truck and a piece of heavy machinery on Highway 27 and Range Road 250. 

City crews were out on the roads early to salt the major routes around Calgary and prevent ice build up.

"They'll be salting the roads, particularly in areas where there's trouble spots — so bridge decks and hills, that kind of thing," said Julie Yepishina-Geller, spokesperson with the City of Calgary.

The city says it's not anticipating very much snow to accumulate on the roads because of the relatively high temperatures.

Snow plows have not been sent out but Yepishina-Geller says they do have the ability to call in extra crews if the weather takes a turn for the worse.

Crews worked throughout the day and night to try to make sure all major roads were cleared for Monday morning's commute.
