Air Resource Advisor: Andrea Holland

FIRE, WEATHER AND SMOKE SYNOPSIS

Weather and Fire Behavior Summary: Change is in the air with the passage of a cold front expected to move across the area Sunday afternoon. With an expected increase in west winds this afternoon, fire activity is expected to pick up from what we have been seeing over the last several days.

Smoke Summary: Winds may pick up today and provide some relief from smoke. However smoke will continue to return to higher concentrations as it pools into the valleys tonight. Seeley Lake’s air quality may “improve” for a few hours after noon with variable levels closer to USG and possibly Moderate. Arlee is expected to see Moderate conditions most of this afternoon with heavier smoke concentrations returning tonight and approaching Unhealthy levels. Clearwater is likely to see Moderate to conditions throughout most of the day with heaviest concentrations around USG briefly making an appearance late this evening before returning to Moderate for most of the night. NOTE: two additional monitoring sites have been established: Condon and Rainy Lake. Tomorrow’s forecast will include these two new sites.
