Special weather statement in effect for:

  • Metro Vancouver

First light snow over the South Coast...

A ridge of high pressure building over the BC Interior is forcing Arctic air south through the Fraser Canyon and west through the mainland inlets and valleys along the coast. The leading edge of the cold, dense outflowing air - the Arctic front - will cause wind speeds to increase as the air temperature decreases.

A small influx of moisture with the Arctic air will create light, fluffy, very low-density snow. As the ground freezes and the wind persists, the accumulating snow will reduce visibility in blowing snow.

The Arctic air will absorb moisture from the sea as it crosses the Strait of Georgia. When the modified Arctic air moves onshore along the East Coast of Vancouver Island, local snow streamers - similar to lake effect snow - may develop. Snowfall accumulations will vary significantly over small distances, ranging from a trace to 5 to 10 centimetres. Rapidly variable and brief blizzard-like conditions may develop in snow-belt and blizzard prone areas of the Lower Mainland such as Sumas Prairie, the Gulf Islands, and on the East Coast of Vancouver Island.

The public is advised to monitor future forecasts and warnings as warnings may be required or extended.
