Southwest Oregon smoke outlook for Oct. 2 and 3

Southwest Oregon should see continued clearing along the coast as we head into the weekend, but more smoke is in store for inland valleys.

Here's the full smoke outlook for Friday and Saturday by Seth Morphis, the air resource advisor, assigned to the fires.

Fire
The Slater and Devil fires remain active as crews continue to focus on line construction. More detailed information can be found at: Slater/Devil Fires Inciweb Information
Smoke
The high pressure ridge that has been affecting the forecast area will shift to the east today and allow onshore flow to increase through Saturday. This should bring some improvement to air quality, notably for the coastal communities, but interior valleys should see some improvement as well. Surface winds will be from the NW starting this afternoon; however, higher level transport winds will continue with enough southerly component to bring high level smoke from the south. Some of this smoke will likely mix down to surface again in the evening. Those in Happy Camp and the Seiad Valley will likely see the heaviest concentrations as smoke pools in the Klamath this evening/overnight. Folks in the Illinois Valley, Applegate Valley, and Grants Pass can expect to see some smoke throughout the day, with concentrations increasing overnight. Coastal communities should begin to see improvement this afternoon and that should continue through Saturday.
