"The ongoing wildfire activity affecting portions of the western United States and western Canada continues to produce enormous amounts of smoke that covers most of Canada and the northern portion of the United States. The areas of densest smoke extend from western and southern British Columbia across Alberta, Saskatchewan, Manitoba, Ontario, and southern Quebec in Canada and northern California, southern Oregon, all of the northern border states from Washington to Michigan, Wisconsin, Iowa, Illinois, and Missouri in the United States."
PM2.5 monitoring has shown Good to Unhealthy for Sensitive Groups air quality across Western, South-Central, and South-East Washington counties today. Continued Unhealthy to Hazardous conditions have been monitored in the Central and North-Eastern counties. Conditions look to get progressively worse for western Washington as well as most other counties over the next few days.
Please protect you and your family from smoke if it is impacting your area. The Department of Health has relevant information here.
