Heavy Smoke in Northwestern CONUS; Lower Levels of Smoke Throughout North American Region

GOES-WEST images from the Hazard Mapping System Fire and Smoke Product show heavy smoke concentrations in parts of Montana, northern Oregon, and northeast Washington State (Figure 1).  This is due to several wildfires in these areas reported by INCIWEB.  Particularly heavy smoke continues to emanate from the still active Williams Flat Fire in Washington State south of the Colville Reservation (Figure 2).  INCIWEB  reports that this is a 18,000 acre fire caused by a lightening storm on August 2, which incited burning inside of a Game Reserve.  The fire has proven difficult to contain due to the rough terrain and unstable weather conditions.  Only 25% of the perimeter has been contained and local authorities continue to tend to the situation (Figure 3).

A more general view of the hazard map actually indicates lower levels of smoke throughout the North American regions than as of late.  This is a positive development for the region which has recently been largely covered with light smoke from fire activity.
