Snow In Vancouver Expected Sunday Night

HuffPost BC

Snow removal crews in Vancouver are preparing the city's major roads in anticipation of snow on Sunday afternoon and into Monday morning.

Seventeen people were on shift at the National Works Yard near Main and Terminal this morning — 15 more than what is normal on Sundays — and 20 trucks were out salting and sanding the city's 14 major bus routes and roads. Though some crew members are being sent home early because of the changing weather.

"The fine details of this process are often not predictable until the day of the storm, if at all. The regions affected, the amount of snow that falls prior to the change to freezing rain, and the duration of the freezing rain remain forecast challenges," said Environment Canada in a special weather statement for Metro Vancouver on Sunday. 

The weather service says a complex system is moving east across B.C. on Sunday evening and into Monday, replacing freezing Arctic air with milder Pacific air. There is a 30 to 40 per cent chance of flurries along the South Coast overnight, with possible snow accumulations up to five centimetres. Howe Sound could get up to 10 centimetres of snow.

Arctic outflow and snowfall warnings are in effect for the inland sections of the Central and North Coast, with high winds and possible snow accumulations of 20 to 30 centimetres. Wind chill values of -25 C are expected. 

By Monday morning, snow could change to freezing rain across Metro Vancouver, the Fraser Valley, and possibly over parts of Vancouver Island. Rain with temperatures between 3 C and 5 C are expected for the rest of the week.
