The air agency is warning even healthy adults to avoid walking or exercising outside in King and Pierce counties today. While ozone - the other "usual suspect" in poor air quality - is an irritant to lungs, fine particulate matter is a health risk because it gets deep into the lungs and blocks air sacs. Current air quality levels in Darrington are UNHEALTHY for everyone.

Officials have extended the air quality advisory for the Bay Area through Tuesday, saying they expect winds to blow smoke into the area. Conditions will begin to improve overnight from north to south as the smoke plume begins to exit the region.

Huge clouds of choking smoke from the wildfires have prompted air quality advisories for much of Western Canada and forced the cancellations of two triathlons in B.C.'s Okanagan region on Sunday.

Satellite images show strong northeast winds carried smoke across the Cascades from fires burning in Eastern Washington on Monday afternoon. This map is from Monday night; black dots are "hazardous", purple dots are "very unhealthy", and the red dots are "unhealthy".

On Tuesday, most parts of the state were considered moderate in terms of air quality, according to the EPA's AirNow site. The agency recommends everyone stay indoors as much as possible. That's almost double the number of smoke-related alerts issued by the agency from 2008 to 2015, the seven previous years.

It is due to smoke from more than 500 forest fires blowing across the Canadian border, blanketing large areas of the Pacific Northwest.

Children, elderly folks and people with respiratory illness could experience scratchy throats, itchy eyes and coughs. If you have an air conditioner, use the "recirculation" switch.
