Wildfire Smoke Continues to Impact Sacramento Region
Smoke from the Camp Fire burning in Butte County is being transported into the Sacramento region. Smoke from this fire will continue to be seen through the week depending on the strength and direction of the winds and the fire status.

Due to the unpredictable nature of wildfire smoke, particulate matter levels can be elevated in one area, but not in another.

If you see or smell smoke, go inside, close doors and windows to reduce or eliminate your exposure. If you must be outside please reduce strenuous activity.

Air Quality Forecast and Weather Discussion
Thursday and Friday, periods of northerly winds will transport smoke from the Camp Fire into the Sacramento region. In addition, winds will be light, limiting smoke dispersion. Furthermore, an upper-level ridge of high pressure will reduce atmospheric mixing, trapping pollutants near the ground. Therefore, particle levels will be Very Unhealthy on Thursday and Unhealthy on Friday. Saturday, light onshore winds in the early morning and late evening will aid mixing in the Sacramento region. However, lingering smoke from the Camp Fire will result in Unhealthy for Sensitive Groups particle levels.
