Fire: Firing operations will take place South of
the Wishon Reservoir along the Crown Valley Trail today. Fire in the Kennedy
Grove area, southeast of Hume Lake, continues to move southeast in a slow to
moderate rate of speed with short range spotting. Fuels and topography to the
east become more broken which will cause the rate of speed to slow. Fire will
continue to spread west from Highway 180 toward Converse Basin. Rapid rates
of spread are expected in the drainage bottoms along the King River. These
runs are expected to stall as they reach the ridge anchored by Converse Peak.
The
fire is now 60,238 acres and 25% contained.
Air Quality
Today: Heavy concentrations of smoke are
expected near the fire and in drainages below active burning in the western
foothills and areas within the Kings River Canyon until noon. Transport winds are expected to begin
increasing today pushing smoke into Owens Valley where moderate impacts are
expected in the late afternoon as smoke is lifted and transported into the
valley. This evening smoke will once
again settle into the Kings River Valley, with impacts expected in areas near
the fire through tomorrow morning.
Air Quality Tomorrow: As transport winds are expected to increase,
areas south of the fire, which have experienced significant impacts the last
few mornings, as smoke settled overnight, should expect significantly better
conditions tomorrow morning. Transport winds are expected to push the smoke northeast
of the fire. Significant impacts will
continue in areas near the fire and in areas directly below active fire
overnight.
