8/12/13 Idaho DEQ Smoke Forecast


Smoke Forecast for 8/12:

·         Southwest Idaho can expect to see moderate to significant smoke impacts from the Elk and Pony Complex fires.  Winds will take the smoke from these fires to the north during the day.  During the evening, the smoke will drain into Mountain Home and the SE Treasure Valley, as well as the mountain valleys.  The heaviest impacted areas will continue to be Lowman, Atlanta, and Idaho City and surrounding areas.  Smoke will be heaviest during the nighttime and early morning hours and should clear out some during the day.

·         South-central Idaho will be impacted by the Beaver Creek Complex fires.  North winds will take the smoke into Stanley and Ketchum areas.  During the evening the smoke will drain into the Snake River Valley. Smoke will be heaviest during the nighttime and early morning hours and should clear out some during the day.  Ketchum is currently experiencing air quality in the unhealthy.

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

·         DEQ installed a monitor in Challis for the Lodgepole fire. The information can be found at http://app.airsis.com/USFS/ Choose monitor #Idaho1004
·         The USFS installed monitors in Lowman, Atlanta, and Challis.  The information can be found at http://www.wrcc.dri.edu/cgi-bin/smoke.pl
o    Lowman monitor is Smoke#19
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.  Communities nearby active fires may experience periods of air quality which are Moderate (visibility of 6-10 miles).  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.
