Air Quality Report Issue Date: 09/14/2015
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: Smoke is being produced by interior burning
combined with burnout operations along containment lines which are designed
to stop the spread of the fire to the west. The fire is 139,188 acres, containment
is 40%.
Air Quality
Today: The
smoke that has been impacting the foothill communities west of the fire
should see clearing skies as the winds move up from the southwest and west
today. This will shift the impacts to those areas immediately adjacent to the
wildfire, and to the Owens Valley to the east and northeast of the incident. Mostly
moderate impacts are anticipated due to the reduction in active burn areas,
with a few areas of higher readings in close proximity. Overall, much improved conditions
throughout the impact area.
Air Quality Tomorrow: Similar smoke conditions are forecast for
the modeled area, with continued impacts to the Owens Valley.
