Environment Canada meteorologist Dan Kulak told the Edmonton Journal areas outside the city could receive as much as 15 inches of snow before the system moves to the east.
Before sunrise Thursday, the city deployed 50 sanding trucks to major roads and streets. By midday, there were 100 snow removal trucks and plows working to clear roads, officials said.
By 10 a.m., police had responded to 62 minor car crashes linked to the snow, police spokesman Scott Pattison told the Journal.
There was no immediate report of injuries associated with the storm.
Heavy snow caused tree branches to break and take down power lines, and the Epcor power utility had all available crews working to repair the lines, the Canadian Broadcasting Corp. said.
Temperatures were expected to drop to 20 degrees overnight, leading to concerns the city's slush and melt would be solid frozen by Friday morning, the report said.
