The Day After Yesterday: Spring snow storm wallops Calgary

The winter storm warning may be over, but Calgary will be digging its way out this morning after as much as 20 centimetres of snow fell in the area.

A Winter Storm Warning for the Calgary area from Environment Canada officially ended early Sunday, but temperatures will remain chilly for the day.

The spring blast of snow has forced the cancellation of the Calgary Police Half Marathon and has roads covered in snow and ice around the city.

“Road conditions and course conditions are poor and out of caution, this year’s race has been canceled to ensure everyone’s safety,” the Calgary Police Half Twitter account tweeted early Sunday.

More information on the cancellation can be found here.

A bus slid and rolled last night on the Trans-Canada Highway west of Calgary with 15 people on board. Another crash with a handful of semis and as many as 11 vehicles had traffic at a standstill and RCMP had closed the road.

A Blizzard Warning remains in effect for parts of southeast Alberta and the Trans-Canada Highway from Calgary to just about Brooks is still closed, according to 511 Alberta.

We’ll continue to post more information as it becomes available.
