Smoke is expected to increase over the coming days

Smoke impacts today are anticipated to expand. Expect impacts at the surface to be light, as most of the smoke is being transported into the region from fires burning in central California, Oregon, and Washington. Moscow and the Spokane-Coeur d’Alene corridor into Idaho should expect to see both surface smoke and smoke aloft today. Local impacts on a shorter duration should be expected in the vicinity of Garden Valley, the Northern Magic Valley, and Owyhee County due to local fires in those areas. The AQI forecasts are expected to remain elevated for those regions.

Expect an increase in smoke impacts in areas near active fires in the coming days

Due to the high pressure system at the surface and limited horizontal movement of air expect an increase in smoke production from any active fires and the accompanying increase in smoke impacts at the surface near these fires during the overnight hours over the coming days. AQI forecasts are expected to be elevated slightly due to activity in those areas while remaining in the Good category in most other areas around the state.

Expect any smoke impacts today to be light or of short duration.

Smoke impacts today will be across southwest Idaho and north to around the 44th parallel. Expect impacts at the surface to be light, as most of the smoke is being transported into the region from fires burning in central California and Nevada. This will provide for decreased visibility aloft. Local impacts on a shorter duration should be expected in the vicinity of Garden Valley as well as the Northern Magic Valley due to local fires in those areas. AQI forecasts are not expected to be affected on a 24hr level in those spots, but be aware of short temporal impacts.

This image shows possible smoke being advected from central California and Nevada and into southwestern Idaho. A locally high concentration in the vicinity of Garden Valley is suggested.

Smoke Outlook through Monday

Barring the start of any major fires near Idaho this weekend it looks like we will get mostly Good air quality into Monday.
Dry, northwest flow will usher in warm temperatures and benign weather for Friday across all Idaho airsheds. Due to the zonal flow pattern, expect similar conditions throughout the weekend with a slight chance for isolated thunderstorms to develop in the afternoons and evenings of Saturday, Sunday, and Monday over the Central Idaho Mountains and along the Eastern Highlands and Southern Highlands south of Twin Falls, ID. 
On Sunday, winds will slacken slightly and range from 2-8 mph across the state and be from the west, again with northwest to southwest deviations from west to east. Wind speeds and directions will be similar on Monday.

Smoke impacts are expected to be minimal through today.

Several small fires have been reported in Idaho this week. Fortunately these have remained small and not impacted local air quality with great significance or a long-term event. Unfortunately three fires in Eastern Idaho appear to have been started by target shooting Firefighters are about halfway to containment of the 440,000 acre Martin Fire in Nevada. That’s one to watch for a while as this fire has the potential to impact areas of Southern Idaho. Smoke impacts are expected to be minimal through today.

What is an air quality Forecast and Caution and how does it impact me?

During wildfire season, you will likely see DEQ issue an air quality Forecast and Caution to inform the public when smoke concentrations have reached, or are forecasted to reach and persist, at levels likely to affect your health.  A Forecast and Caution is intended to help you make informed health choices for the day and to limit further buildup of pollution in the affected areas.

The Forecast and Caution will include specific warnings and advice to those most susceptible to the effects of smoke.  It also prohibits intentional open burning on state and federal lands until the Forecast and Caution is lifted.

Let’s hope we have very little need for any Forecast and Cautions notices this summer and avoid wildfires altogether!

Idaho could experience an above-normal wildfire season this summer. The Idaho Department of Environmental Quality (DEQ) suggests planning your wildfire response now to keep your family safe and limit exposure to wildfire smoke.

According to National Interagency Fire Center’s Predictive Services forecasts, Idaho is expected to be above normal for significant wildland fire potential in July and August. View their June forecast summary here.


DEQ recommends taking the following steps to prepare for the upcoming wildfire season:
  • Bookmark air quality reporting websites. Many of these websites display current air quality conditions and provide links to smoke forecasts and ways to help you plan ahead. Recommended air quality websites are listed below.
  • Do your research and make a plan. Develop a family evacuation plan, work with your doctor on a prescription medicine plan, or equip your home with clean air resources. It all takes time, so start working now on the best solutions for your family.

2017 Idaho Wildfire Season Recap

Notice: This blog is not routinely managed after the Idaho wildfire season has effectively concluded. If you are looking for air quality information when wildfires are not active in Idaho please consider visiting Idaho Department of Environmental Quality's air quality forecast and burn map page at: .

Idaho Wildfire Season Recap

Fire starts began in July and continued into August. By early August wildfire smoke began to impact Idaho’s residents. By the first week of September under warm and very dry conditions wildfire smoke thoroughly blanketed all of Idaho exposing many of Idaho citizens to potentially serious health impacts. The most severe air quality impacts this season were experienced in communities in north and central Idaho where Hazardous Conditions were measured for four days in the Coeur d’Alene area.

September number of days with Hazardous air quality from PM2.5 Particulate Pollution
Wildfires burned on over 5 million acres in Idaho, Washington, Oregon, Montana, and British Columbia Canada combined. Over 700,000 acres were affected by wildfire in Idaho this year.
  • Idaho wildfires in 2017 released over 111,000 tons of direct fine particulate pollution (PM2.5) into the air. This is equal to 10 times the amount of particulate pollution that all the cars and trucks in Idaho emit over a three year period.
