There are widespread areas of significant smoke pooled across the region. As winds increase and fire activity picks up during the afternoon, rapid and significant changes in smoke and air quality can occur.
The August Complex continues to actively burn along the NW/W perimeter. The Zogg Fire SW of Redding and Glass Fire in Napa Valley continue to produce smoke.
High pressure continues to dominate the region allowing for strong inversions. Smoke that is trapped in the valleys will remain with widespread Unhealthy conditions. Communities in deep valleys could see periods of Hazardous air near the August Complex. This is likely to occur in the Mad River, Hayfork, Ruth Lake, Van Duzer, and Eel River areas. These conditions will continue through the weekend. There could be some slight improvement for coastal communities as onshore flow increases the next few days.
