Yesterday, Metro Vancouver has issued an Air Quality Bulletin for Metro Vancouver and the central Fraser Valley due to possible intermittent high concentrations of fine particulate matter this weekend.

And, while the current air quality is still considered fair, the forecast calls for some high concentrations later today. However, the forecast calls for clearer air tomorrow.

Metro Vancouver notes that Air Quality Bulletins are issued when air pollutant levels are expected to be elevated, but do not yet exceed levels that warrant the issuance of an Air Quality Advisory. As such, the authority hasn't issued an advisory yet, but the bulletin is still in effect.

In fact, the Air Quality Index Data Map, which is updated hourly, currently shows that the air quality has a low health risk and is ideal for outdoor activities. With this in mind, the current forecast for Metro Vancouver shows that this will air quality will worsen, and that that there will be a moderate health risk.

The index shows that there will also be a moderate risk tonight, but that tomorrow the risk will be low.

As a result of this forecast, people with chronic underlying medical conditions should consider postponing strenuous exercise until the bulletin is lifted. What's more, exposure is particularly a concern for pregnant women and infants, the elderly and those who have diabetes, and lung or heart disease.

Populations who are not at risk do not need to modify their usual outdoor activities unless they experience symptoms such as coughing and throat irritation.

If you are experiencing symptoms such as chest discomfort, shortness of breath, coughing or wheezing, follow the advice of your healthcare provider.

This bulletin is expected to continue until there is a change in the current weather.
