Environment Canada warns of wildfire smoke and high temperatures in Metro Vancouver

      A high-pressure weather system is continuing over B.C., which is going to cause a very hot Labour Day.

      That's prompted Environment Canada to issue a special weather statement for Metro Vancouver.

      "Under this weather pattern, the air mass will also become increasingly stagnant," it says. "Combined with developing outflow winds, wildfire smoke is expected to make its way out to the coast again, beginning today."

      The record temperature for September 4 was 27 °C in 2003. That could be shattered later today.

      Inland temperatures will climb over 30 °C, according to Environment Canada.

      "Computer weather models continue to indicate that the ridge will be quite persistent with the hot weather lasting until at least Wednesday," the statement says.

      Meanwhile, Metro Vancouver has issued an air quality advisory for Metro Vancouver and the Fraser Valley because of high concentrations of fine particulate matter.

      These are droplets or solid airborne particles measuring 2.5 micrometres or less in diameter.

      Some of the particulates are from wildfires burning in Washington state, whereas others are from other parts of B.C.

      "Smoke concentrations may vary widely across the region as winds and temperatures change, as well as fire behaviour," Metro Vancouver said in a statement today.

      The regional district has advised avoiding strenuous activity, particularly in the late afternoon and evening.
