Friday September 5, 2014 Smoke Impact Summary - Klamath NF

Yesterday Winds pushed smoke to the Southwest which impacted the communities of the lower Klamath, Salmon, and Trinity River drainages.  Dispersion was good and kept most of the smoke aloft and from settling into drainages. Today Smoke is predicted to travel southwest down the Klamath and Salmon River drainages in the morning hours.  By afternoon, smoke will change directions and head eastward to the Scott and Shasta Valley.  Smoke concentrations are forecast to be more localized as dispersion is predicted to be low.  This means that communities surrounding the active fires will be impacted by smoke until the weather changes. Tomorrow Weather will be similar to the previous day.  Smoke is forecast to pool into valleys and drainages with low dispersion.  Communities to the west of the fires may experience improved conditions as an onshore flow pushes the smoke slightly westward.
