Sunday, August 23, 2015 - Rough Fire Air Quality Report

Air Quality Report                                                                                              Issue Date: 08/23/2015

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: In the Southern Zone, there was very little active burning overnight which allowed for additional control of the fire, especially in the Hume Lake area. Direct fire suppression will continue along Road 13S09 Spur K in the Tenmile Creek area near Landslide Campground. This operation will tie the fire into Road 13S26.  In the Northern Zone, crews were engaged in blacklining from the Bailey Bridge toward Balch Camp and progressed approximately 1 mile up from the bridge. Blacklining operations also occurred along 2 miles of Balch Camp Rd from Balch Camp working back toward Bailey Bridge. As the fire approaches the North Fork, blacklining operations are anticipated over the next few days. The fire is now 47,396 acres.
Air Quality Today:   With very little burning overnight, the western foothills saw some relief from smoke this morning.  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.
