Incident Type | Wildfire |
Cause | Lightning/natural |
Date of Origin | Thursday August 05th, 2021 approx. 10:30 PM |
Location | 7 Miles NE of McKenzie Bridge, OR |
Incident Commander | Randy Johnson, Pacific Northwest Team 3 |
Coordinates | 44.246 latitude, -122.055 longitude |
Total Personnel | 46 |
Size | 544 Acres |
Percent of Perimeter Contained | 50% |
Estimated Containment Date | Wednesday August 25th, 2021 approx. 12:00 AM |
Fuels Involved | Timber (Litter and Understory) Closed Timber Litter Light Logging Slash Conifer with abundant brush, small trees and dead/down logs, making it difficult to walk through. Will burn readily with abundant torching and spotting when dry; it doesn't need much wind to spread efficiently, primarily through torching and spotting. Lichen will contribute to torching and spotting as relative humidity (Rh) falls below 40% |
Significant Events | Minimal flanking, torching, spotting. Primarily cleaning up unburned fuels within the line. Torching likely, spotting possible. Wide natural barriers and favorable containment features reduce the likelihood of a spot establishing outside of containment lines. |
Planned Actions | Holding and patrolling all flanks. Patrolling Hwy 126 to the east of Mckenzie River for any potential spotting. |
Projected Incident Activity | 12 hours: Interior torching possible with spotting possible. 24 hours: Interior torching possible with spotting possible. |
Remarks | This will be the last ICS-209 from PNW for this incident. Command will be returned to the local unit at 0600 on 8/16/2020. |
Weather Concerns | Slightly stronger winds have begun to mix down to the surface,increasing ventilation and allowing for smoke to flush out more easily. The earlier clearing of smoke permitted increased air resource operations, and also led to increased solar insolation. As expected, this led to temperatures running a few degrees warmer(highs 85-90) and afternoon humidity being slightly warmer compared to Saturday, despite the weakening high pressure across the Pacific Northwest. Prevailing winds remained out of the west through the day, similar to previous days. Through Tuesday, increasing onshore flow with bring cooler marine air to the area, resulting in very high humidity recoveries during the overnight periods, and moderate daytime humidity values. Some patchy drizzle is possible Monday night, but little no accumulations are expected. Temperatures will take a dive on Tuesday, with highs lowering to the 60s and low 70s. Slightly warmer and drier conditions expected beginning Wednesday. |
