The Northern Sierra Air Quality Management District is issuing an air quality health advisory to notify the public of the potential for poor air quality conditions in Plumas, Sierra and especially Nevada County due to smoke from the American Fire in Placer County. The Fire is burning in steep terrain approximately 11 miles northeast of Foresthill, and has the potential to grow significantly. Smoke is primarily fine particulate matter, but also includes volatile compounds and nitrogen oxides, which form ozone through chemical reactions that are fueled by sunlight and warm temperatures. Therefore, ozone levels may also be elevated at times.
National Weather Service in Sacramento posted the following:
Here is a satellite image this morning centered on the American Fire.
Interestingly two plumes of smoke are evident. One is blowing down the Sierra, with smoke being reported in Auburn.
The other is blowing northward, with smoke being reported in Nevada City, and evident over Blue Canyon and Downieville.
(Aerial Photo: courtesy of Air Attack 17) The fire got started early Sunday morning and grew overnight. No road closures, no evacuations. The town of Foresthill is not threatened. Fire is estimated at 800-1,000 acres. The fire has crossed the North Fork of the Middle Fork of the American River and is burning toward the Last Chance area.
A Type 2 Incident Team has been assigned to the fire. (In the Continental United States and Alaska there are 15 National Interagency Incident Management Teams categorized as Type 1 and 36 teams categorized as Type 2. Both types of teams are strategically located throughout states, which are more prone to wildland fires. The teams consist of members from a wide variety of federal, state, county, and local agencies. Region 5′s Type 1 and 2 teams generally manage large wildland fire incidents and address the most complicated safety, fiscal, planning, operational and logistical issues.) The American fire has crossed the North Fork of the Middle Fork of the American River and is burning toward the Last Chance area.
No structures have been lost.
National Weather Service in Reno reports:
Smoke from the American Fire west of Lake Tahoe will continue to affect the Reno-Tahoe area over the coming days. The American Fire is burning heavy timber on the western slopes of the Sierra, about 25 miles west of Lake Tahoe in the canyon of the North Fork of the Middle Fork American River.
This is a graphic of Hysplit model run of the projected smoke moving into the Reno-Tahoe area Monday evening. West to Southwest winds will push smoke into Reno-Tahoe late in the afternoon and into the evening hours. Green shading shows areas of smoke, while blue shading shows areas of dense smoke.
