Smoke Outlook: Klamathon Fire Issued for: Sunday, June 8, 2018
Air Resource Advisor: Jen Croft
Synopsis
Fire Activity: Fire continues to make short range runs when wind and slopes align, with occasional isolated group tree torching. Areas of grassy fuels are consuming quickly, and responding to suppression efforts. Fire resources are continuing to make progress along the perimeter, utilizing roads and grassy fuel areas when possible.
Smoke: South and southwest winds are pushing the smoke from the fire to the North and Northwest at this time. The smoke is very visible from major highways, and will likely reduce visibility and travel speeds on all roadways in the area near the fire. Expect small particles of ash and falling debris to accumulate on windshields and filters near Yreka and homes around the fire. Night time cooling will cause the smoke to settle into the valleys and drainages, with minimal improvement in conditions expected through most of Sunday. Reduced air movement will cause a limited regional haze to settle into the area, reducing sight distance.

Figure 1- High Resolution smoke image of the Klamathon Fire in the evening 07/07/2018. Greatest concentration is along the Oregon/California border, with some pooling into the adjacent valleys north and south. Expect these conditions to persist until winds increase late Monday night and transport
smoke to the southeast.
Figure 2- Predicted smoke trajectories. Red- low level smoke will disperse to the southeast first, then move north towards Klamath Falls. Blue- high level smoke in the smoke plume will catch transport winds, moving smoke northeast immediately.
