Fire: The fire remained active
overnight along the fire fronts, especially in the canyon areas. Additional
resources are being assigned to the night shift by reallocating day operation
crews in an effort to combat these conditions. The fire is actively backing and flanking
with short range spotting and up- hill runs. Critical fire line will continue
to be constructed from Hwy 180 to the Kings River. The fire is now 55,989 acres
and 25% contained.
Air Quality
Today: With light transport wind, heavy concentrations
of smoke are expected near the fire and in drainages below active burning in the
western foothills and areas within the Kings River Canyon until mid-afternoon. Owens Valley will see air quality degrading
in the morning and late afternoon as smoke is lifted and transported into the
valley. This evening smoke will once
again settle into the Kings River Valley, bringing smoke into the western
foothills and the San Joaquin Valley overnight.
Air Quality Tomorrow: A similar pattern to today is expected.
