Friday, August 14, 2015 - Shasta-Trinity/Six Rivers Complexes - Air Quality Report (Short)

Prepared by Chuck Sams and Dan Chan

Forecast conditions represent impacts from smoke.  Contributions from ozone and other pollutants are not reflected.
Smoke Synopsis:
On Tuesday, based on 24-hour averages, many PM Monitors reported “Good” or “Moderate” air quality in the area.  Weaverville reported “USG” condition.  “Unhealthy” condition was reported at Happy Camp, Yreka, and Etna.  “Very Unhealthy” condition was reported at Hayfork and Hyampon. “Hazardous” condition was reported at Weitchpec.

Today/Tomorrow: Day time mixing will not be as good as the previous days due to lower mixing height and slower transport wind speed because of the establishment of high pressure over the area.  Northweterly/Westerly onshore wind will flow all the way into Shasta County in late afternoon today, but it will be weaker tomorrow and only go into Humboldt/Trinity County line.  Strong Northerly wind is forecast to develop tonight at the Sacramento Valley, but this wind is forecast to weaken tomorrow.  Air quality is likely to deteriorate in the area, especially in Trinity County where the fires are.
