Murky skies, poor air quality in B.C. as more smoke from U.S. wildfires drifts north
Smoke could be an issue for southern parts of province over next 3 three days, Environment Canada says
Heat advisories have ended in British Columbia following several days of record breaking temperatures in some areas, but most of the province is now covered by Environment Canada advisories about wildfire smoke.
A smoky skies bulletin says all but the most northerly regions of the province are likely to be affected by wildfire smoke wafting up from the United States over the next three days. Areas like Prince George may get smoke passing through, but at higher altitudes.
The advisory said forecast models over the next 24 to 72 hours show the potential for long-range transport of smoke from dozens of wildfires in the northwestern United States.
Environment Canada's air quality health index lists air quality at moderate to high risk for most of southern B.C., meaning those with health issues should reduce outdoor activities.
Air quality in Victoria was rated 10+ from early Friday, indicating a "very high" health risk, while in the West Shore area to the city's west, the index was at a "high" rating of 8.
By later Friday morning, the air quality across Metro Vancouver had hit at least a 10 rating, with a 10+ in northwest and southwest quadrants.
Environment Canada predicts the index will sit at 10 through Saturday for the entire Metro Vancouver area.
In the central Fraser Valley, the index hit 8 on Friday and is forecast to rise to 9 on Saturday.
Metro Vancouver advisory
Metro Vancouver issued an air quality advisory Friday afternoon, warning people with chronic underlying medical conditions or acute infections such as COVID-19 to postpone or reduce outdoor physical activity until the advisory is lifted, especially if breathing feels uncomfortable.
Exposure to fine particulate matter in the air is particularly concerning for people with underlying conditions such as lung disease, heart disease, chronic obstructive pulmonary disease (COPD), asthma, diabetes, pregnant women and infants, children, older adults and individuals with respiratory infections.
Individuals who are socially marginalized may also be at elevated risk.
The advisory asks anyone If you are experiencing symptoms such as chest discomfort, shortness of breath, coughing or wheezing to seek prompt medical attention and call 911 in the case of an emergency.

Weather data shows a high pressure ridge is lifting after bringing heat advisories for large sections of the province, but 12 records were set Thursday — including three that have stood since 1944.
Vancouver, Victoria and Pitt Meadows all saw their hottest day in 76 years, while records also fell on Vancouver Island, Sechelt, Squamish, Pemberton, West Vancouver, the Cariboo region of Puntzi Mountain and as far north as Mackenzie.
Recent wildfires have scorched nearly 2,426 square kilometres in Washington state. More than 3,625 square kilometres have burned this week in Oregon, where hot, windy conditions continued. Authorities said more than 500,000 people — more than 10 per cent of the state's population — have been forced to evacuate their homes.
In California, 19 people have been killed and at least 4,000 structures have burned in what officials have called a "historic" wildfire season.
