Sunday, September 13, 2015 Rough Smoke Report and Forecast

Air Quality Report                                                                                              Issue Date: 09/13/2015

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:  The fire perimeter grew yesterday due to persistent warm temperatures and lower relative humidity. Smoke is being produced by interior burning and burnout operations along containment lines which are designed to stop the spread of the fire to the west. Estimated increase in size is 134,000 acres, up approx. 6,000 acres from yesterday - containment is 29%.
Air Quality Today: Heavy concentrations of smoke are expected near the fire and to the west foothills today.  Smoke will be slow to lift and transport will be primarily terrain and diurnally driven. Limited ventilation is forecast for today with continued increased impacts expected in the San Joaquin Valley west and northwest of fire.  Unhealthy to Hazardous conditions are expected in the foothill communities west and northwest of the fire, but improving in the evening. Conditions begin to worsen in the Owens Valley as winds shift south-southwest in the afternoon.    
Air Quality Tomorrow:  A more south to southwest wind will begin to alleviate smoke impacts in the San Joaquin Valley. More smoke will impact the Owens valley.
