8/13/13 Idaho DEQ Smoke Forecast

Smoke Forecast for 8/13:

·         Smoke will be transported to the north and northeast of the fires in southern Idaho.  The satellite image from yesterday morning (below) shows the smoke tracking north and northeast reaching Montana.

·         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 and northeast 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 morning hours and should clear out some during the afternoon.

·         South-central Idaho will be impacted by the Beaver Creek Complex and McCan fires.  Southwest winds will take the smoke into the Stanley and Ketchum areas.  During the evening the smoke will drain into the Snake River Valley. Smoke will be heaviest during the nighttime and morning hours and should clear out some during the day. 

·         Idaho County can expect light smoke impacts from the fires in southern Idaho.

Yesterday morning’s satellite image shows smoke from the Elk and Pony complex fires starting to fill in the east side of the Treasure Valley and continuing south of Mountain Home across the Snake River and into Owyhee County.  The State fire, along the UT/ID border west of Franklin, is still producing a little plume down at the Utah border.

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.
