Fire: On the southern zone, the fire
continues to move towards Hume Lake, and remains well established in the 10
mile drainage. The fire continues to move towards Windy Gulch, Lockwood
Grove, and Evans Grove. On the
northern zone of the fire, it continues to move along the Kings River towards
Balch Camp and Black Rock Power Station. The fire is now 47,079 acres.
Air Quality
Today: With slight changes in weather patterns,
we will see heavy concentrations of smoke in the western foothills and areas
within the Kings River Canyon until midafternoon. 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.
