Fire: The fire continues to be active in the
southwest and potentially threatening the Hume Lake community, which has been
evacuated. In the northwest, the fire
is burning toward the northwest toward Balch Camp. Currently, the fire stands at 30,901
acres. A flight to map the current
perimeter is scheduled for this afternoon.
The complexity of the fire has resulted in a transition to a Type 1
team. The team will be taking over
today.
Air Quality
Today: A similar pattern as yesterday, heavy
concentrations of smoke will remain 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.
