VANCOUVER — An air quality advisory has been issued for parts of Metro Vancouver and the Fraser Valley as air pollution reacts with the warmer weather.
The regional district of Metro Vancouver issued the advisory saying smoke from a wildfire burning north of Harrison Hot Springs is also occasionally reaching into the Lower Fraser Valley, creating a haze that may also be contributing to the ozone levels.
The district says high ground-level ozone is formed when pollutants from burned fuels react with the air in the presence of sunlight.
The advisory is especially aimed at people with chronic, underlying medical conditions.
The forecast for the area calls for temperatures reaching 26 C by Sunday before the weather cools slightly into next week.
