Weather and Fire Behavior:
Yesterday was hot and dry, with temps in the upper 70’s and humidity in the fire area dropping as low as the mid 20’s. A weak cold front is forecast to move into the Pacific Northwest Sunday night into Monday, bringing cooler and slightly more humid conditions. In its wake, another gradual warming trend is expected next week, which will result in seasonally average temperatures and humidity levels.
The fire-moderating effects of last week’s rainfall are diminishing. Warm, dry weather and clear skies have allowed a modest increase in fire behavior and smoke production. Firing operations added to the smoke output and winds out of the west pushed smoke into the Mt. Hood corridor yesterday morning. Similar levels of smoke are anticipated today.
Operations:
Firefighters completed firing operations along the south side of the FS12 road yesterday but need fuels to dry further before they can tie that burned area along the road into the fire’s edge. A swing shift crew was used to monitor the fire line through the night. Today, they will continue testing fuels for receptivity to firing operations, patiently waiting for the opportunity to consume any remaining burnable vegetation between the control line and the fire perimeter.
Much of yesterday’s work included direct attack on the fire’s edge constructing hand line, since the fuels remained too wet to perform firing ops and bring the fire edge to the road. Crews are nearing completion of line construction in the steep terrain between the FS12 and 14 roads on the west flank. They have also been methodically working their way east along the southern flank, building hand line and mopping up as they go. On the fire’s east flank, crews worked to mop up the dozer line created between the FR12 and 1210 roads and will continue mopping up today.
Fire information officers will be stationed at Jonsrud Viewpoint in Sandy, OR on Sunday, September 10th from 1 – 7pm to provide updates and answer questions.
