Saturday, August 22, 2015 - Rough Fire Air Quality Report

Air Quality Report                                                                                              Issue Date: 08/22/2015

Rough Fire – Sierra National Forest                                                            Prepared by: Ariane Sarzotti

Forecast conditions represent impacts from smoke from the Rough Fire.  Contributions from ozone and other pollutants are not reflected.
Fire: On the southern zone, the fire continues to move towards Hume Lake, and remains well established in the 10 mile drainage. The fire continues to move towards Windy Gulch, Lockwood Grove, and Evans Grove.  On the northern zone of the fire, it continues to move along the Kings River towards Balch Camp and Black Rock Power Station. The fire is now 47,079 acres.
Air Quality Today:   With slight changes in weather patterns, we will see heavy concentrations of smoke in the western foothills and areas within the Kings River Canyon until midafternoon.  Owens Valley, particularly Bishop and Mammoth Lakes area, will see air quality degrading as smoke is lifted and transported to the northeast into the Owens Valley.   This evening smoke will once again settle into the Kings River Valley, bringing smoke into the western foothills and the San Joaquin Valley overnight. 
Air Quality Tomorrow:  A similar pattern to today is expected.
