Smoke Synopsis:
Air quality in the area generally improved on Saturday compared to Friday due to better smoke dispersion. PM Monitors at Hoopa, Orleans and Weitchpec reported “Good” air quality on Saturday! Yet, areas in the Trinity River drainage and South Fork Trinity River drainage remained above “Unhealthy” range. Mad River improved from “Unhealthy” to “USG”. Hayfork improved from “Hazardous” to “Very Unhealthy”. Onshore flow today is going bring clean air to Humboldt County, but push smoke from the fires into Trinity County, especially along the Trinity River drainage and South Fork Trinity River drainage. Then, Southwesterly transport wind aloft will bring smoke further Northeast in the late afternoon today. Smoky conditions are likely to persist at Hayfork and Hyampom due to fires nearby. Happy Camp may be impacted by smoke from Oregon. Tomorrow’s condition is expected to be similar to Today. Transport wind direction is expected to turn to Southerly on Tuesday. Yreka, Etna, Mt Shasta, Weaverville, and Anderson are likely to have much better air quality on Tuesday.
