Winter has made a nasty return to the city and Calgarians contended with slippery streets and sidewalks across the city on Wednesday.

CTV Calgary Meteorologist David Spence says the heaviest snow was centered on the city at about 3:45 p.m. and will taper off into the evening.

He says the latest projected snow accumulation totals show about 5 cm of snowfall for the city by noon on Thursday.

The white stuff is slowing traffic to a crawl on many streets and emergency crews responded to several crashes throughout the day.

Northbound Strathcona Blvd. at Bow Trail in the southwest was shut down after one incident and traffic in the area was diverted.

There were also collisions at Highway 8 at 69 Street and Highway 8 at 101 Street S.W. in the afternoon.

The drive home will likely be slow going and motorists are advised to drive to conditions.
