City officials say crews are making good progress on clearing the roads, so there will be no parking ban on snow routes Monday or Tuesday.

However, Mayor Naheed Nenshi does say an overnight ban is still possible for Tuesday night.

Meanwhile, slippery roads have resulted in several accidents.

From 7 a.m. Sunday to 4 p.m. Monday, there have been 284 accidents reported to Calgary police with 19 of those resulting in injuries.

Crews worked through the night to clear the city’s Priority 1 roads — the major commuter routes that see 20,000 vehicles or more per day. Priority 2 routes — ones that carry 5,000 to 19,999 vehicles per day — will be cleared next, the city said.

"We brought in some extra help and equipment to make sure the roads were in good condition. It was a big dump of snow we got and we were working all night," said Kelly Dyer with the city's roads department.

Many southern Alberta highways were closed because of the winter storm, which created zero-visibility conditions at times.

According to Environment Canada downtown Calgary got 9 centimetres of snow, 12 centimetres fell at the airport and west of Calgary saw as much as 27 centimetres.

At the Calgary International Airport dozens of flights were cancelled, redirected or delayed on Sunday. The airport experienced its second power outage in as many weeks.

Several times throughout the day all runways were closed so crews could clear the snow.
