An air quality advisory has been issued for the Fraser Valley Regional District and Metro Vancouver because of fine particulate matter stemming from wildfires elsewhere in the Pacific Northwest.
Metro Vancouver, which is responsible for air quality monitoring, issued the advisory Wednesday afternoon.
People with chronic underlying medical conditions are urged to avoid strenuous exercise until the advisory is lifted.
Exposure is of particular concern for infants, the elderly and those who have diabetes and lung or heart disease.
To reduce exposure, residents are urged to stay indoors and in air-conditioned spaces.
The advisory is expected to carry into Wednesday, when rain showers are forecast.
