Fire: Firing operations will continue today south
of the Wishon Reservoir. Fire in the
east is will continue moving southeast through
Evans Grove and along the Boulder Creek drainage. Fire in the Converse Basin area has become more active with uphill runs from the Kings River drainage southwest toward Hoist Ridge. The fire is now 61,316 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: With continued southwest
transport winds, daytime smoke is expected to be transported to the northeast. With active fire expected overnight, smoke
impacts are again expected in drainages below active fire and in drainages south
of the fire.
