      A blast of Arctic air is coming to B.C.'s south coast and Vancouver Island. And that could possibly bring snow beginning on Sunday (December 4) evening.

      "Temperatures will plummet 5 to 10 degrees below normal with overnight minimums around minus 5 when the cold air reaches the South Coast Sunday evening," Environment Canada stated in a weather alert this morning. 

      The bulletin noted that "there is plenty of uncertainty around the arrival of snow, the areas affected and snowfall amounts".

      "The earliest potential for snow is Sunday night when the cold air first arrives," Environment Canada added. "On Wednesday an incoming stronger Pacific system with mild air overrunning the cold air at the surface will boost the chance of snow again. The snow should disappear by late in the week, as warmer air returns."

      The City of Vancouver says it's calling in work crews to salt and brine major routes later today and tomorrow.

      There are 44 trucks in the fleet that can apply salt. According to the city, there are already 1,500 tonnes of salt ready for use. There's also equipment to place salt on bike routes.

      "If the weather turns to freezing rain, efforts will focus on salting and brining roadways, and on clearing storm drains to prevent any potential flooding problems," the city stated in a news release.

      Residents and businesses are responsible for clearing snow and ice around their properties by 10 a.m. following any snowfall. Those who fail to do this could be subject to fines.
