Current Wildfire Smoke Info


Smoke Forecast: Friday, August 28 through Monday, August 31, 2015

Air quality is currently ranging from Good to Moderate in southern Idaho and Moderate to Hazardous across northern Idaho with higher impacts across the Clearwater Basin drainage, northern Panhandle, and Salmon-Challis area. Air quality is forecast to remain in the Unhealthy for Sensitive Groups to Unhealthy category for the 24-hour standard across central and northern Idaho today and into this weekend. Impacts are from regional fires burning in Washington state, California, Oregon, and a multitude of local fires in the Clearwater drainage, northern Panhandle, and central Idaho mountains.

Nez Perce Reservation: 24-hour monitor readings range from Unhealthy for Sensitive Groups to Hazardous. Hourly readings are fluctuating from Moderate to Hazardous, depending on location and wind direction. The Nez Perce Tribe will continue their air quality advisory.  Please contact the Nez Perce Tribe for more information:

The strongest smoke impacts are occurring across the Clearwater drainages, central Idaho mountains, and the northern Panhandle. This will continue tonight and become even stronger on Saturday as high winds provide an increase to fire activity across the Columbia Plateau and into central and northern Idaho. Expect to experience impacts from the Canada border south to the Salmon River corridor with some drainage impacts into the McCall and Garden Valley areas tonight. The highest impacts are expected to be within the drainages of the Clearwater, Salmon, Lochsa, down into the Lewiston-Clarkston Valley. The northern tier of the Purcell Trench will also continue to experience high impacts throughout the entire weekend. In southern Idaho, impacts will be greatest within the drainages around McCall and Garden Valley and generally north of a line running from Weiser to Salmon. Conditions have generally improved across southern Idaho with values in the Good and Moderate range across all monitors, except for McCall and Salmon, which are reading Unhealthy for Sensitive Groups and Hazardous, respectively. Nighttime drainage smoke will continue to provide impacts in regions near and downwind of the fires. Impacts in the central Idaho region will continue to be quite strong as winds will serve to increase fire activity on Saturday. As a result of increased fire activity, strong impacts are also expected to occur within the Purcell Trench across the Rathdrum Prairie and north into Canada with more clearing over the open expanses.

Smoke forecasts are dependent on predicted fire growth and weather. If conditions change unexpectedly, impacts could occur.

Air Quality Conditions

Under Idaho’s Air Pollution Emergency Rule, DEQ may issue air quality alerts when pollutant levels reach levels that endanger public health. The alerts range from Stage 1 to 4, with each stage addressing a progressively more serious air quality event and triggering certain emergency actions.

Air Quality Monitors

Note: Idaho DEQ does not have jurisdiction within the five Indian Reservations in Idaho. For air quality information on the reservations, contact the individual Tribes.

Visual Smoke Observation

Smoke forecasts are dependent on predicted fire growth and weather. If conditions change unexpectedly, impacts could occur. When visibility starts to go below 5 miles, sensitive groups should minimize outdoor activities. Everyone else should minimize prolonged or physical activity outdoors. Refer to the Smoke and Health Tab on the Idaho Smoke Information Blog for additional health information.

Your eyes are your best tools to determine if it’s safe to be outside. Even if you smell smoke, the air quality may still be good.

How to estimate air quality based on visibility for areas without an air quality monitor or airport visibility estimate:

  1. Face away from the sun.
  2. Determine the limit of your visible range by looking for targets at known distances (miles).
  3. Visible range is that point at which even high contrast objects totally disappear.
  4. Use the values above to determine the local forest fire smoke category.
