Fire: Firefighters worked diligently yesterday to
slow the growth of the Rough Fire towards Hume Lake. Air resources, including
helicopters dropping water, and fixed-wing aircraft using fire retardant, in
conjunction with firefighters on the ground working to create
firelines. On the northwest portion of the fire, crews are working to
protect the Pacific Gas and Electric infrastructure in the Balch camp area. The fire is now 39,400 acres.
Air Quality
Today: With little change in weather patterns,
we will continue to see heavy concentrations of smoke in the western
foothills and areas within the Kings River Canyon until midafternoon. As smoke is lifted it will be transported
to the east, degrading air quality in the Owens Valley. This evening smoke will once again settle
into the Kings River Valley, bringing smoke into the San Joaquin Valley
overnight.
Air Quality Tomorrow: A similar pattern to today is expected.
