A winter storm blew in on Sunday bringing flurries and freezing temperatures and Calgarians are being cautioned to use care when walking and driving around the city.

Between 15 to 20 cm of snow has fallen in parts of Southern Alberta since Sunday and temperatures are expected to drop throughout the day on Monday.

Weather experts say the frigid weather will continue all week and with a windchill it could feel a lot colder.

In Bridgeland, hills in the community turned out to be so slippery on Sunday that crews blocked off streets and sidewalks so they could be cleared.

"Up until about two years ago, it was pretty good," says Barrie Robb, who lives along one of the inclines in the area. "They had sanding trucks here as soon as it snowed, as soon as it was icy. The roads would clear off because it had a southern exposure."

Robb says that service seems to have dropped off in the past few years. "I'm not sure what has happened, but we see a lot less of the sand and salt trucks," he said. "It's due to road conditions as well as people thinking they're invincible."

In the downtown core, crews were hard at work first thing in the morning clearing sidewalks and the Stephen Avenue Walk.

"We have sweepers, which are further up ahead, they do all the major areas. We just do around the posts and the chairs that are out here," said worker, Ron Anderson.

Calgarians are taking it in stride and many say it is Alberta after all.

"I just have to dress up a little bit warmer but I can handle it. I've been out in minus 38 so I don't mind, It's outdoors," said dog walker, Carrie Wagner.

Some Calgarians were hopping on a plane to get out of the city and head to warmer climates on Sunday.

“I just told my daughter we are leaving winter to go to summer,” said Julia Meek, who was heading to Mexico.

“I was excited because I didn’t want to be stuck in -13 and stuff,” says Chad Meek.

Lennart Klein works for Foothills Landscaping and says he started on Sunday at 5:00 a.m. clearing snow from city sidewalks.

"It keeps us busy, but that's good," said Klein. "All of our snow crews are out, all around the clock pretty much from in the middle of the night until late night and yea they're all out shoveling, sweeping, hauling it all away."

Klein says layers and hydration are key to staying warm.

Service shops are also working around the clock, installing winter tires on vehicles for customers, and say people should call ahead for an appointment.
