Seattle, WA – The air quality in north King County reached unhealthy levels Friday evening, prompting health advisories for residents to limit outdoor activities and stay indoors where the air is cleaner. This deterioration comes as wildfire smoke continues to affect much of Central and Eastern Washington, with many areas experiencing moderate to unhealthy air conditions.
Wildfire Smoke Brings Health Concerns to King County
High pressure systems have driven smoke from wildfires down to the surface, particularly at higher elevations, resulting in degraded air quality across the region. According to KING 5 Meteorologist Ashley Ruiz, the conditions are expected to persist, with air quality levels remaining moderate to unhealthy for sensitive groups until rain and better weather conditions arrive.
- Moderate air quality poses risks for individuals unusually sensitive to air pollution.
- Unhealthy air for sensitive groups increases health risks for people with heart and lung conditions, diabetes, older adults, and children.
“The air quality is expected to remain moderate and unhealthy for sensitive groups before rain chances return to the Puget Sound from Saturday through Tuesday,” said Ashley Ruiz.
Extensive Wildfires Fueling Smoke in the Region
The wildfire smoke affecting King County originates largely from uncontrolled fires across Canada and Washington state.
- As of the end of August, 31 major wildfires remain uncontrolled across Canada, burning over 19 million acres.
- In Washington, some significant fires include:
- Bear Gulch Fire near Lake Cushman on the Olympic Peninsula — over 10,000 acres burned.
- Pomas Fire west of Lake Chelan in the Cascades — over 3,500 acres burned.
- Sugarloaf Fire near Entiat — over 7,000 acres burned as of Friday morning.
Visible Effects of Smoke and Upcoming Weather Outlook
The heavy wildfire haze has caused striking visual effects in the region, including turning the nearly-full moon and the sun a bright red hue. The upcoming Corn Moon, set to rise on September 7, will occur amid smoky skies.
Wildfire haze is expected to linger until an atmospheric system or onshore flow pushes the smoke out. The forecast indicates the arrival of a first wave of showers on Saturday morning, followed by increasing chances of widespread rain early next week as a low-pressure system moves inland, contributing to improved air quality.
