Forest

Synopsis
|
Smoke: Smoke will remain in the vicinity of the Chetco Bar fire
today, drifting to the southwest in the morning and then to the south in the
afternoon. The morning inversion over
the fire will break up around 10:00 am.
The smoke column will be visible later in the day around Grants Pass, Cave
Junction, Gold Beach, and Brookings, however air quality is expected to
remain good. A light haze may be
present.
Smoke from adjacent fires such as Blanket Creek
fire and the Orleans Complex in Northern California will add to a regional
haze in some parts of southern Oregon.
Fire: Chetco Bar fire activity continues to be minimal, growing approximately
230 acres yesterday to 2,410 acres. Fire
activity today and tomorrow is expected to increase as a result of continued
warmer and drier weather patterns. This
may lead to increased smoke output around the fire vicinity.
Other: Agness monitoring station was added 7/29. Medford and
Ashland forecasts from this fire will be removed today due to negligible
smoke impacts from this fire into the Rogue Valley.
