08/11/2016 Idaho DEQ Smoke Forecast

Updated 10am MDT Thursday, August 11, 2016

Valid through Noon MDT Friday, August 12, 2016

Smoke Outlook

Air quality is forecast to continue to remain in the Good to Moderate air quality category across the state today.  All DEQ monitors are currently reading in the GOOD category this morning except for Garden Valley, Nampa, and Boise which are currently reading in the MODERATE category.

Today will continue to experience a warming trend as an upper level ridge establishes from the west.  Wind speeds will be in the 5-15 mph range from the west-northwest with northwest to northwest winds over the Camas Prairie and southwest winds over the Upper Snake River Plain and Purcell Trench.  Wind directions over northern Idaho will be generally will be from the west-southwest.  Wind speeds at the surface will range from 10-15 mph in southern Idaho and 5-10 mph in northern Idaho.  Mixing heights will range from 3,000 feet AGL to 7,000 feet AGL. 


Smoke impacts today are expected to continue to be local in nature.  Smoke is expected to impact communities near active fires with morning drainage into the Upper Treasure Valley and Stanley region.  Smoke from the Power Line Fire outside American Falls will generate smoke in that area with transport to the northeast once the inversion breaks.  This evening will see nocturnal drainage down the Boise-Mores into the Lower Snake River Plain.  Tomorrow will see limited impacts across the Upper Treasure Valley in the morning and Northern Magic Valley before clearing in the afternoon.

·         Lowman, ID monitor is Lowman-Jolene Drive

·         Boise, ID monitor is Garden City-Alworth Street

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.  Visit the Idaho Smoke Blog for more information at http://idsmoke.blogspot.com/

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:

a. Face away from the sun.
b. Determine the limit of your visible range by looking for targets at known distances (miles).
c. Visible range is when an object you can easily see in the distance disappears.
d. Use the visibility values above to determine the local wildfire smoke category.
