The smoky air has returned to the south coast of B.C., which provides a new air quality advice for Metro Vancouver and the central Fraser Valley.
Residents had a short delay in the weekend due to an explosion of cool, wet weather that cleared many of the fine dust particles, but officials said wildfires were back before Sunday morning.
"This has resulted in increased levels of fine particulate matter that exceed our air quality targets across the region," said Metro Vancouver in his advice.
An existing air quality recommendation for the eastern Fraser Valley, including Agassiz and Hope, has also been extended.
Officials said the elevated levels of fine suspended particles are expected to continue "until there is a change in weather or fire conditions."
Fine particulate matter refers to solid or liquid droplets in the air that are small enough to enter houses and buildings.
Poor air quality poses a particular risk for infants, the elderly and people with lung disease, heart disease or diabetes. Anyone with a chronic medical condition is warned to postpone strenuous efforts until the advice is lifted.
Officials also recommend that anyone who experiences symptoms such as discomfort in the chest, shortness of breath, coughing or wheezing, goes to a healthcare provider.
Last week worried residents put all available medical masks on the market at a number of local drug stores, hoping to protect themselves against the thick, smoky air.
Health officials have warned that only N95 mask masks are able to block the fine floating particles.
