Monday, September 21, 2015 - Rough Fire Smoke Report and Forecast

Air Quality Report                                                                                               Issue Date: 09/21/2015

Rough Fire                                                                                                     Prepared by:  Tod Johnson 
Forecast conditions represent impacts from smoke from the Rough Fire wildfire.  Contributions from ozone and other pollutants are not reflected.
Fire:  Burnout operations and interior fire spread yesterday increased fire size by 351 acres bringing the current fire area total to 141,950 acres.  Burnout operations to clean up interior unburned islands will continue today to prevent spotting across containment lines.  Fire perimeter containment is listed at 68%.
Air Quality Today:  Fire activity and perimeter burn out operations will disperse light to moderate emissions into areas directly South and South West of the fire as conditions hamper smoke dispersal. The foothill communities west of Kings Canyon will experience light to moderate smoke impacts as smoke moves West this afternoon and  into Tuesday morning. Stable air conditions will limit relief from night time settling and pooling.  Better mixing to occur following inversion break around 1100 AM. Some light impacts to the Northern communities of Owens Valley anticipated this afternoon.
Air Quality Tomorrow:  Smoke will linger through the morning hours beneath the inversion. Ground impacts to recover following 1100 AM inversion break. Impacts will to be light to moderate in the foothills west of the fire. Heavier impacts to persist for the areas proximal to King’s Canyon.  Improving conditions overall as high pressure exits.
