Metro Vancouver has issued an air quality advisory for the Metro Vancouver area and the Fraser Valley due to high concentrations of fine particulate matter that are expected to persist for several days.
The developing weather pattern over the B.C. Coast is causing outflow winds to carry smoke from wildfires burning in the Interior towards the region. This advisory is expected to continue until there is a change in the current weather.
Smoke concentrations may vary widely across the region as winds and temperatures change, as well as fire behaviour.
Fine particulate matter, also known as PM2.5, refers to airborne solid or liquid droplets with a diameter of 2.5 micrometres (μm) or less. PM2.5 can easily penetrate indoors because of their small size.
Persons with chronic underlying medical conditions should postpone strenuous exercise until the advisory is lifted. Exposure is particularly a concern for infants, the elderly and those who have diabetes, and lung or heart disease. If you are experiencing symptoms such as chest discomfort, shortness of breath, coughing or wheezing, follow the advice of your healthcare provider. As we are in the summer season with warm temperatures, it is also important to stay cool and hydrated. Indoor spaces with air conditioning may offer relief from both heat and air pollution.
Metro Vancouver works in cooperation with Environment and Climate Change Canada, the Fraser Valley Regional District and B.C. Ministry of Environment to look after air quality.
