Rough Fire – Sierra
National Forest Prepared
by: Rick Graw
Forecast conditions represent impacts
from smoke from the Rough Fire.
Contributions from ozone and other pollutants are not reflected.
|
|||||
Fire: Yesterday, the Rough Fire grew by 3400
acres, to a perimeter of approximately 13,400 acres. A large pyrocumulus cloud was observed over
the fire at 4 pm, when afternoon southwest winds aligned with the middle fork
of the Kings River, which increased fire behavior, and allowed the fire to
reach into heavier fuels.
Air Quality Today: Air quality is diminishing over much of the
forecast areas as high pressure gets established and decreasing
dispersion. Afternoon transport winds
will be from the southwest transporting smoke towards the Owens Valley. Smoke
concentrations tonight will be heavier than last night in the communities
east of the fire.Air Quality Tomorrow: Poorer dispersion conditions caused by the increasing influence of the high pressure system will result in poorer air quality over much of the area. |
