Fire: Fire remains active in three primary areas: south of the Wishon Reservoir on the north
side of the fire; in the Converse Creek drainage area; and in the South Fork
of the Kings River west of Cedar Grove. The fire is now 66,542 acres and is
25% contained.
Air Quality
Today:
Transport winds are expected to push the smoke northeast of active fire today. Owens Valley will see air quality degrading
as smoke is lifted and transported to the northeast, particularly from
Independence north towards Bishop from late morning through midnight. Significant impacts will continue in areas
near the fire and in areas directly below active fire overnight.
Air Quality Tomorrow: Light transport winds are
expected to be from the south tomorrow, so daytime smoke is expected to be
transported to the north, with greater levels of smoke in the drainages into
the San Joaquin Valley overnight. With
active fire expected overnight, smoke impacts are again expected in drainages
below active fire and in drainages south of the fire.
