from smoke from the Rough Fire wildfire.

Fire: Interior fire activity and more accurate
mapping added an additional 455 acres bringing the current fire area total to 141,491acres. As fuels dry out, additional burning
operations along the western perimeter will likely continue until the edge is
secure. Fire perimeter containment is
listed at 68%.
Air Quality
Today: Increased fire activity and
perimeter burn out operations will disperse light to moderate smoke into areas
directly South and South West of the fire as the N—NE winds move into the
area. Hume Lake, Grant Grove, Cedar
Grove, Ash Mountain and Three Rivers are the areas of highest impact. The
foothill communities west of Kings Canyon will experience light to moderate
smoke impacts as smoke moves West through the evening into Sunday morning.
Stable air conditions will limit relief from night time settling and pooling.
Air Quality Tomorrow: Smoke will linger through the morning hours
beneath the forecast inversion. Ground impacts to lessen following inversion
break and as a result day time heating. Impacts continue to be light to
moderate in the foothills west of the fire. Heavier impacts to persist for
the areas proximal to King’s Canyon. Limited impacts to the Owens Valley.
