Air Quality Outlook:  Shasta-Trinity & Six Rivers Complexes
Prepared by Chuck Sams, Erin Law and Dan Chan

Forecast conditions represent impacts from smoke.  Contributions from ozone and other pollutants are not reflected.
Smoke Synopsis: Friday morning update
Monitoring stations in the area are at or above “Unhealthy to Sensitive Groups” level yesterday.  Hayfork was in “Hazardous” level.  Weaverville was in “Very Unhealthy” level yesterday.  Good day-time mixing is expected during the day for the next few days.  Transport wind speed will gradually increase from today through Monday.  Transport wind direction will be Westerly/Southwesterly for today and tomorrow.  Heavy smoke is still likely in river drainages in Shasta-Trinity National Forest during the overnight periods until inversion break the following morning.   Air quality at Hayfork, Hyampon, Mad River/Dinsmore, and Weaverville are likely to be very poor in the night time periods.
