Current Wildfire Smoke Info

Smoke Forecast: Wednesday, August 24 through Thursday, August 25, 2016

Air quality is forecast to continue to remain in the Good to Moderate air quality category across the state today with higher readings across Boise, Custer, Bonneville, and Teton couties due to the proximity and drainage of the Pioneer Fire as well as fires in western Wyoming. Current elevated DEQ monitors include Salmon, Rexburg, Franklin, Garden Valley, Idaho City, Pinehurst, Potlatch, Lewiston, and the Coeur d’Alene tribal monitor in Plummer which are all reading in the Moderate Category. Idaho Falls is currently reading in the Unhealthy category.
Smoke from the Pioneer Fire will affect the Ketchum area within the Big and Little Wood drainages into the Arco Desert to Pocatello. This afternoon, a northwest to west wind will provide some clearing out of the Snake River Plain with impacts confined to mainly east of Mountain Home and east through much of the Upper Snake. New fire starts this past weekend look to produce smoke across eastern and southeast Idaho with impacts into the Idaho Falls, Rexburg, Teton Valley, and Island Park area and south to Soda Springs. An easterly wind across northern Idaho will remove impacts from fires in Washington; however, it will bring morning smoke from Montana fires this morning before lifting out this afternoon. Tonight, drainage smoke will again enter the Lower Snake River Plain east of Boise as well as down into the Middle and Upper Snake via the Arco Desert extending east to Island Park. Tomorrow, widespread light smoke aloft is expected into the afternoon from the Middle Snake east to Idaho Falls. Brief, morning impacts should be expected across the Silver Valley, Clearwater drainages, and Columbia Basin. Read more on the Idaho Smoke Information Blog

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.

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.
