A Smoky Skies bulletin has been issued for Howe Sound, Sunshine Coast (south), and Whistler.
Smoke from wildfires in the US is affecting air quality in the region and has caused an increase in fine particulate matter (PM2.5) concentrations.
This event, however, will be short in duration and less intense than the previous event in September.
Widespread haze and moderate Air Quality Health Index levels are expected to continue until Sunday, when a change in weather will likely develop and clear out the smoke.
During a wildfire, smoke conditions can change quickly over short distances and can vary considerably hour by hour, the ministry added.
“Wildfire smoke is a natural part of our environment but it is important to be mindful that exposure to smoke may affect your health,” the Ministry of Environment said.
People with pre-existing health conditions, respiratory infections such as COVID-19, older adults, pregnant women and infants, children, and sensitive individuals are more likely to experience health effects from smoke exposure.
Exposure to wildfire smoke and the virus that causes COVID-19 can both result in respiratory symptoms such as a dry cough, sore throat, or difficulty breathing.
