Bulter Fire and Salmon River Complex-Air Quality Report
Incident: Forks Complex (includes Butler Fire ) Wildfire
Yesterday, August 12, 2013
Similar conditions to the day before were seen. Smoke inversions broke early giving all areas at least a few hours of improved air quality. Most areas remained in the good to moderate range all day and into the evening. Increased fire activity on the Corral Complex caused afternoon smoke impacts in Sawyers Bar, Forks of Salmon, Somes Bar, Fort Jones, Etna, and Yreka. Most areas improved by early evening, with the exception of Sawyers Bar and Forks of Salmon.

Smoke from the Butler Fire and Salmon River Complex will impact Somes Bar to Orleans in the early morning hours starting around 4:00 AM. The smoke will start to lift around 2:00 PM as southwest winds pick up. Residual smoke will linger over Willow Creek, Hoopa, and Weitchpec through the nighttime hours. Smoke from the Corral Complex will roll in around 9:00 AM possibly reaching the unhealthy for sensitive groups range. This smoke will start to clear around 2:00 PM and by 6:00 PM AQI levels will return to the moderate to good range. Happy Camp will be in the good range most of the day with a couple of hours that might reach moderate levels. For Etna, Ft. Jones, and Yreka, light smoke and haze throughout the morning and early afternoon, increasing around 3:00 to 4:00 PM when AQI levels will reach the moderate range. Forks of Salmon and Sawyers Bar will be in the unhealthy for sensitive groups range all day, becoming unhealthy during the nighttime hours.

Smoke in the early hours will pool in the Somes Bar and Orleans areas; AQI levels may reach unhealthy for sensitive groups for a short time between 4:00 and 6:00 AM. Weitchpec, Hoopa, and Willow Creek will have better air quality during the early morning with moderate AQI. Strong south to southwest winds will clear smoke out of the area starting around 11:00 AM, a little bit earlier than usual. This will transport smoke north and Happy Camp may border on the moderate range by mid-day. By 2:00 PM Etna and Ft. Jones will see elevated smoke levels that could reach unhealthy for sensitive groups, possibly becoming unhealthy for an hour or two. By 8:00 PM light haze will cover the region, with AQI values hovering between good and moderate levels.
Over the next couple of the days south to south-west transport winds will help to keep the air quality in the moderate range. Towards the end of the week, the winds will weaken and switch to the north to northeast Saturday and into Sunday. Atmospheric dispersion will also decrease, reducing smoke transport and increasing the chance for poor air quality.
