Air Quality Alert due to Rim FIRE

Shifting winds bring heavy smoke from Rim Fire to California, Nevada, Idaho

Heavy smoke from Rim Fire has filled Yosemite Valley, and much of central California, Nevada and Idaho.

RIM FIRE became the 4th largest wildfire in California history after devouring about 223,000 acres (901km², or 348mi²) on Saturday, including about 6.5 percent of Yosemite’s backcountry, as it targeted two groves of YNP’s very old sequoia trees.

Heavy smoke has obscured scenic views and previously unaffected areas of Yosemite, reports said.

Air Quality Alerts and Dense Smoke Advisories have been issued for multiple counties across a vast region.

The San Joaquin Valley, Mariposa County and Tuolumne County Air Pollution Control Districts have issued an Air Quality Alert due to smoke Impacts from the Rim Fire in Mariposa, Merced, Madera, Fresno, Kings, Tulare, Tuolumne and the valley portion of Kern counties. —NWS
