This site is an effort by county, state, tribal, and federal agencies to coordinate and aggregate information for Idaho communities affected by wildfire smoke. The information is posted here by the agencies themselves.

**(Preliminary Data Warning: Data found on the map shown below is preliminary and is subject to change. Data is in local standard time format - no adjustment for daylight savings time.
Air quality is
forecast to continue to remain in the Good to Moderate air quality category across
the state today. Current elevated DEQ
monitors include St. Maries and Boise, which are reading in the Moderate
Category. Salmon is reporting in the
Unhealthy for Sensitive Groups Category.
Continue to expect higher readings and impacts in the morning before
clearing after 1pm.
level low pressure system in the Gulf of Alaska will continue to provide a
southwest steering flow for all of Idaho today. This system will remain
entrenched for some time -at least through Wednesday- as it sends weak lobes of
energy over Idaho through the week. We should see increased cloud cover and
slightly cooler temperatures which should help suppress some fire activity. For today, surface wind speeds will range
from 5-15 mph with higher speeds across the Central Idaho Mountains. Surface wind direction will be from the
south-southeast across the Lower and Middle Snake with southwest winds across
the Upper Snake. Expect northwest to
southwest winds across northern Idaho. Mixing
heights will range from 2,000-13,000 feet AGL.
Transport wind speed will be between 5-15 mph and be from the
southeast-east to southwest. Ventilation
is forecast to be POOR in the morning and GOOD in the afternoon with locally
MARGINAL ventilation across much of southwest Idaho. Expect POOR to locally MARGINAL ventilation
across all of northern Idaho outside Shoshone and Benewah Counties. Inversions
are expected to break between 10am-1pm.
The Pioneer fire will continue to produce smoke
as it grows. Expect to see impacts
across the Upper Snake this morning before clearing to the northeast once the
inversion lifts. This morning, expect to
see smoke north of a line running from Terreton to Ashton. Dispersion this afternoon looks to be good
and will promote clearing after the inversion lifts around 12noon-1pm today
over southern Idaho. Smoke will push
nearly due north into the west-central Mountains today. The southerly flow pattern will help move
smoke out of the Snake River Plain today but looks to shift to the southwest
and continue to move smoke from the Pioneer Fire into the Salmon area via
Stanley and Challis. Expect lofted smoke
over the Nez Perce Tribal lands, the Weippe and Camas Prairies. Smoke looks to push as far north as the
southern end of Lake Pend Oreille late this evening. Elsewhere tonight, expect smoke to drain into
the Ketchum area and into the Snake River Plain. Tomorrow, continued
south-southwest winds will keep smoke out of the Snake River Plain and the
strong southerly component looks to move smoke just north of Salmon, providing

·Fairfield, ID monitor is Fairfield-Soldier Road
·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.

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.
