Light smoke and haze all over - several counties with Air Quality Advisory in effect

Today’s air quality is forecast to be in the Moderate to Unhealthy for Sensitive Groups range for most of the state. The Treasure Valley and Clearwater Basin could see brief periods of Unhealthy.

Smoke from California, western Montana, Central Washington, Oregon, and local fires are impacting Idaho. Patchy smoke and haze are seen across South Idaho, East Idaho and the Central Mountains, while light smoke and haze are seen in North Idaho. The westerly afternoon winds and potential thunderstorms will help disperse near surface smoke and haze. The wind will continue to nudge the smoke and haze eastward and into Montana, Wyoming, and Utah while light smoke and haze will linger across South Idaho, East Idaho, and the Central Mountains with areas of smoke near local fires tomorrow afternoon. The pattern of smoke becoming trapped under inversions during the evenings and raising the AQI before limited clearing the next mornings will continue.

Check the Idaho Open Burn Map to see if your location has an Air Quality Advisory in effect.
