A smoke advisory will be in effect through Saturday in most of Los Angeles County and parts of Orange, Riverside and San Bernardino counties due to a wildfire burning in the Angeles National Forest that has blackened 26,368 acres and is only 6% contained.
The Bobcat Fire, which broke out at midday Sunday near the Cogswell Dam and West Fork Day Use area, prompted evacuation warnings in seven San Gabriel Valley foothill communities and was not expected to be fully contained until Oct. 15.
Friday evening, the U.S. Forest Service reported that both “western and eastern sections of the fire continue heading into previous fire scars, lessening the fuel intensity for crews.”
The most fire activity was in the north and south ends of the fire, the U.S. Forest Service said.
“Night operations will continue to patrol the perimeter of the fire across Angeles Crest Highway 2 and state Route 39, as priorities remain to keep infrastructure to the south safe and maintaining the fire to the south and west.”
Through Saturday, smoke and ash are expected in portions of Los Angeles, San Bernardino, Riverside and Orange counties, and unhealthy or higher Air Quality Index levels due to PM2.5 concentrations are possible in areas of direct smoke impacts through Saturday, according to the South Coast Air Quality Management District.
Evacuation warnings remain in effect in the foothill communities of Duarte, Bradbury, Monrovia, Sierra Madre, Pasadena, Altadena and Arcadia.
The Angeles Crest Highway 2 was closed from Upper Big Tujunga Canyon Road to Big Pines and Highway 39 was closed at Old San Gabriel Canyon Road to the Angeles Crest Highway 2.
