Air Quality Summary Report - Liberty and Rice Ridge Fires For: Sunday, August 13, 2017
Air Resource Advisor: Andrea Holland
FIRE, WEATHER AND SMOKE SYNOPSIS
Weather and Fire Behavior Summary: Strong and shifting winds are expected today influencing fire behavior and generally pushing the fire to the east and northeast. Valley bottom winds will be considerably stronger than what we’ve been seeing the past several days. Fire activity is expected to pick up today which means more smoke production later this afternoon.
Smoke Summary: Gusty winds may clear out some of the smoke this afternoon. Tonight, however, smoke is expected to drift back into valley communities. Seeley Lake’s air quality will see some relief this afternoon with variable levels between USG and Moderate; smoke will settle in tonight approaching Unhealthy levels. Arlee is expected to see Moderate conditions most of today with heavier smoke concentrations returning tonight and approaching Unhealthy levels. Clearwater may be hazy most of today. Rainy Lake and Condon will see better air quality today than their neighbors to the south.
