Air Quality Report Issue Date: 09/17/2015
Rough Fire Prepared by: Tod Johnson and Jen Croft
Forecast conditions represent impacts
from smoke from the Rough Fire wildfire.
Contributions from ozone and other pollutants are not reflected.
|
|||||
Fire: Additional efforts to secure the perimeter
with burnout operations along the western boundary have been made, and will
continue as the drying trend improves the opportunities and burning conditions. Current perimeter is 141,036 acres, 276 new
acres resulting from the above efforts.
The Rough fire is 67% contained.
Air Quality
Today: Increased fire activity
will disperse light to moderate smoke into areas directly South and South
East of the fire as the N—NW winds move into the area. Grant Grove, Cedar Grove, Three Rivers, and
the Owens Valley are the areas of highest impact today. As stable air starts to return to the area,
these areas can expect limited relief from night time settling.
Air Quality Tomorrow: N-NE winds will begin to shift the smoke
down the crest, drifting into the upper foothills, with some settling into
the lower valley. Impacts are expected
to be light to moderate.
