|
Fire: On the southern zone, fire crews
continue to construct dozer lines along the McKenzie Ridge and a critical line is near
completion from Hwy 180 to the Kings River.
On the northern zone of the fire, hand and aerial firing is
anticipated to continue over the next several days to keep the fire
backing to the north fork of the King’s River. In the Wishon area, structure protection and
hazard reduction efforts have been initiated to protect properties and
infrastructure including the PG&E power grid at Balch Camp and Black
Rock. The
fire is now 51,794 acres and 17% contained.
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 mid-afternoon. Owens Valley will see good air quality for
most of the day, changing to moderate in the afternoon and evening. This evening smoke will once again settle
into portions of 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.
