NEVADA CITY, Calif. July 19, 2017 – Tomorrow morning promises to be another hazy start to the day. Smoke from the Detwiler Fire has been steadily streaming northeast and will once again settle over the Foothills and especially the east side of the Sierra overnight.

The Northern Sierra Air Quality Management District (NSAQMD) is issuing an air quality advisory for Plumas & Sierra Counties to notify the public of potentially poor air quality conditions at least through Monday, July 24, caused by the Detwiler Fire in Mariposa County. Eastern parts of Sierra and Plumas Counties are likely to see the most smoke. It is important to monitor the smoke and make outdoor plans accordingly.

Foothill locations in Nevada, Yuba, Placer, Amador, Alpine and El Dorado counties are likely to be affected as well, with the fire being extremely active.

As a reminder, 911 is not a fire information line – emergencies only. Check your local media for updates on the Detwiler Fire and any new starts.

If you are sensitive to smoke, please take precautions as suggested by NSAQMD:

  • 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 or chronic health issues should stay indoors;
  • Contact your doctor if you have symptoms of cough, shortness of breath, chest pain, or severe fatigue.
