Fire: The fire was active north
of Highway 180 and west of Junction Vista Point. Sustained crown runs
occurred from the canyon bottoms to ridgetops. Crews are engaged in perimeter
control connecting fire lines down to Kings River and from Cherry Gap to
McKenzie Ridge. 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. The fire is now 55,900 acres and 21% 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 air quality degrading
as smoke is lifted and transported to the northeast late afternoon to
midnight. 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.
