A powerful winter storm that developed off the Rockies brought upwards of 20 cm of snow to parts of Alberta over the weekend.
In Calgary, over 10 cm was reported creating slick and dangerous conditions on the roads. Many highways south of Calgary were closed on Sunday because of the poor driving conditions.
To avoid crashing or getting stranded, Mounties told highway drivers to pull into the nearest town and sit tight until conditions improved.
"It's not good. There's drifting snow, limited visibility, icy roads and a lot of vehicles in the ditch," said Cpl. Cate Dickman at the RCMP detachment in Oyen, Alberta, where officials declared a local state of emergency late in the afternoon.
Dickman said the community, which is about 250 km northeast of Calgary, was working to put up travellers in the local Royal Canadian Legion overnight.
While Highway 2 to Calgary was reopened by the early evening hours on Sunday, police said travel on all roads in the area was still not recommended.
Calgary's International Airport remained open on Sunday although several flights were cancelled because of the storm.
Winter storm warnings remained in place for parts of southeastern Alberta early Monday, but conditions are expected to improve throughout the day.
"Parts of Alberta will continue to see some flurries and wraparound snow as the Clipper continues to move east on Monday, but the snow is dying off very quickly so conditions will definitely start to improve," says Mark Robinson, a meteorologist at The Weather Network.
All this comes on the heels of a warm-up that saw temperatures climb into the positive double-digits late last week, breaking temperature records dating back up to 90 years.
The system is made up of moisture from the same system that lashed B.C. this week. It brought torrential rain to the lower mainland and Vancouver Island, and enough snow to the higher elevations to spark rare 'extreme' avalanche ratings.
