Widespread smoke today

Air quality is forecast to range from GOOD to UNHEALTHY across the state today.

Near-surface smoke will remain widespread across the state and moderate smoke will persist across North Idaho and Snake River Plain today. 

Overnight, smoke will settle into valleys and other low-lying areas under strengthening surface-based temperature inversions. As temperatures begin to increase Thursday morning, inversions will begin to break and allow for better circulation across the state. Increased westerly winds by mid-day will also aid smoke dispersion.

Air Quality Advisory and Burn Ban in Effect for Coeur d'Alene Tribe

Air Quality Advisory and Burn Ban in Effect for Kootenai Tribe *corrected

 

EPA Announces an Air Quality Advisory and Ban on Open Burning for the Kootenai Reservation

 

Contact Information: EPA Region 10 Press Office (r10_press_team@epa.gov )

 

Seattle (July 31, 2026) — U.S. Environmental Protection Agency and Kootenai Tribe of Idaho issued an air quality advisory and ban on open burning on the Kootenai Reservation due to increases wildfire smoke from multiple fires in Washington. This advisory and burn ban is effective immediately and will continue until further notice.

 

Smoke from these fires will impact the reservation today and through the weekend and as a result, intermittent periods of Unhealthy for Sensitive Groups and Unhealthy air quality are expected, based on EPA's Air Quality Index. These same conditions may continue into next week. EPA is using agency’s resources to monitor air quality and provide the public with timely access to our data. People should avoid outdoor exercise and minimize exposure to outdoor pollution as much as possible. For more health information, visit Wildfire Smoke Readiness and Response for Region 10 Tribes. The agency will do everything in our authority to continue to protect human health and the environment.
