Fire: In the Southern Zone, there was very
little active burning overnight which allowed for additional control of
the fire, especially in the Hume Lake area. Direct fire suppression will
continue along Road 13S09 Spur K in the Tenmile Creek area near
Landslide Campground. This operation will tie the fire into Road 13S26. In the Northern Zone, crews were engaged in
blacklining from the Bailey Bridge toward Balch Camp and progressed
approximately 1 mile up from the bridge. Blacklining operations also
occurred along 2 miles of Balch Camp Rd from Balch Camp working back
toward Bailey Bridge. As the fire approaches the North Fork, blacklining
operations are anticipated over the next few days. The fire is now
47,396 acres.
Air Quality
Today: With very little burning overnight, the
western foothills saw some relief from smoke this morning. Owens Valley, particularly Bishop and
Mammoth Lakes area, will see air quality degrading as smoke is lifted and
transported to the northeast into the Owens 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.
