Fish Fire, Sequoia National Forest - Air Quality Report Friday, August 30, 2013
Prepared by: Ryan Bauer, USDA-Forest Service
Yesterday, August 29, 2013
There was no growth of the Fish Fire. The current size is 2,056 acres. Heavy fuels continued to burn within the perimeter of the fire producing light smoke through the day. Infrared imagery of the fire from early this morning found only scattered heat within the firelines. Air quality readings for fine particulates (PM 2.5) remained in the good range throughout the day for all areas including Kernville, Springville, Pinehurst, Ash Mountain, Porterville, Lone Pine, and Bishop.

Very light generally haziness was present in the Kern River Valley this morning; this should clear out of Lake Isabella and Kernville before noon. Today will start slightly warmer and drier than yesterday, before another band of monsoonal moisture transits the area bringing higher humidity and another chance of showers and thunderstorms to the fire area. Some burn-down of heavy fuels will continue within the fire perimeter, but smoke production will continue to taper off today and tomorrow. Smoke impacts will be confined to the immediate fire area and should not impact any of the nearby communities.
Saturday, August 31, 2013
Monsoonal moisture will keep higher humidity and a threat of thunderstorms over the fire area. Smoke production from the Fish Fire will be dramatically reduced. Smoke impacts are possible in the San Joaquin Valley from the Rim fire to the north.
Long-range outlook
The threat of thunderstorms lingers through Sunday before diminishing. Daytime humidity should remain high through the period, limiting fire activity and smoke production. Drier southwest flow returns early next week. This will be the last Air Quality Report produced for the Fish Fire.
