The Northern Sierra Air Quality Management District and the Plumas County Public Health Agency are extending and expanding the current joint Air Quality Health Advisory to notify the public of the possibility of poor air quality conditions resulting from the Beckwourth Complex Fire in addition to other wildfires in northern California.  Smoke from the Beckwourth is mainly expected to travel northeast, impacting the Frenchman Lake and Dixie Valley areas.  Chilcoot, Vinton, Lake Davis, Portola and surrounding communities may also experience smoky conditions at times.  In addition, there is the potential for wind shifts to carry smoke to other parts of Plumas County from the Beckwourth and several other regional wildfires.  Air quality is expected to vary greatly depending on fire behavior and weather conditions, with smoke settling in low areas at night and in the early mornings as long as these fires are active.

Exposure to elevated PM2.5 (fine particulate matter in smoke) concentrations can result in eye and throat irritation, headaches, nausea, shortness of breath, congestion, coughing, impaired lung function and chest pain, especially among sensitive individuals such as the elderly, children, people with asthma, people with heart or lung conditions, pregnant women and anyone who is exercising or working hard outdoors.  People who are affected by, or susceptible to, COVID-19 may be at increased risk from wildfire smoke due to cardiovascular symptoms or a compromised or suppressed immune system.

If you smell or see smoke around you, the following actions are recommended:

  • Minimize outdoor activities even if you are healthy;
  • Stay indoors with doors and windows closed as much as possible; run the air conditioner on the “recirculate” setting if that is an option;
  • People with asthma should follow their asthma management plan;
  • People with heart disease, respiratory conditions or chronic health issues should stay indoors;
  • Contact your doctor if you have symptoms of cough, shortness of breath, chest pain, or severe fatigue;
  • Keep airways moist and stay hydrated by drinking plenty of water;
  • Avoid breathing additional smoke, such as from cigarettes or barbecues.

Near real-time air quality conditions for Quincy, Portola, Chester, Truckee and Grass Valley may be found at (click on your location of interest in the “Local Air Quality” portion).  As you view the most recent data, take into consideration that conditions can change rapidly due to wind shifts; it is wise to monitor the smoke throughout the day and make plans accordingly.  The smoke may be visible in satellite imagery, available via (near the bottom of the page).
