8/21/13 Idaho DEQ Smoke Forecast

Updated Noon MDT Wednesday, August 21, 2013
Valid through noon MDT Thursday, August 22, 2013 

Smoke Outlook

Idaho DEQ has issued a Stage 1 Forecast and Caution the following counties
·         Camas, Blaine, and Lemhi – The Stage 1 is effective through Friday, August 23, at which time it will be re-evaluated and either extended or lifted.

The Ketchum/Hailey area is continuing to experiencing Very Unhealthy to Hazardous air quality in the morning due to smoke from the Beaver Creek fire.  Significant smoke impacts are expected to continue in the Ketchum/Hailey area through tomorrow morning.  Air quality will improve during the afternoon hours before smoke moves back in during the night.  Air quality is forecasted to be in the Unhealthy with periods in the Hazardous for Ketchum/Hailey and moderate to unhealthy for sensitive groups for other areas in the central Idaho mountains near the fires.

Salmon is experiencing Unhealthy air quality due to smoke from the Thunder City Fire, which is located 4 miles east of Stibnite, Idaho.  Salmon will continue to experience unhealthy air quality for most of the day today.  Air quality may improve to the moderate category for a couple of hours this afternoon before deteriorating back to the Unhealthy category.  So far, Challis has not been impacted by smoke from the fires in central Idaho.  Salmon is forecasted to be in the Unhealthy for Sensitive Groups to Unhealthy today.

Atlanta is beginning to experience significant smoke impacts due to the Little Queens fire, which is located north of Atlanta.  Air quality is forecasted to be in the Unhealthy for Atlanta today and tomorrow morning.

Sensitive groups such as people with heart and/or lung disease, adults over age 65, young children, and pregnant women should avoid all outdoor activities until air quality improves. Everyone else should minimize outdoor activities.  When air quality is in the hazardous category (visibility of less than 1 mile) everyone should stay indoors and avoid exertion.

Light west winds will continue to transport smoke towards the east today and tomorrow morning.  However, the smoke will not be transported very far from the fires before the evening inversion sets up which will bring the smoke back down to the surface.  Smoke from the Incendiary fire near Kamiah in north central Idaho is expected to be transported to the southeast; however, tonight the smoke should drain down valley and settle in the lower valleys.

7 emergency monitors have been installed in Idaho to help monitor smoke impacts from wildfires:

·         DEQ has installed monitors in Mountain Home, Fairfield, Ketchum, and east Boise. The information can be found at
o    Fairfield – #Idaho1000

·         The USFS installed monitors in Lowman, Atlanta, and Challis.  The information can be found at
o    Lowman monitor is Smoke#19 – monitor currently is not functioning properly, the data is not considered valid
o    Atlanta monitor is Smoke#13
o    Challis monitor is Smoke#21
o    Users should be aware that the Forest Service site reports the data in Coordinated Universal Time (UTC).  To convert from UTS to Mountain Daylight Time, subtract 6 hours.

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.
