Washburn Fire Update- Monsoonal moisture began to increase across the region yesterday afternoon with cumulus buildup visible to the east of the Washburn fire over the Sierra Crest. Moisture will increase again today with thunderstorm activity becoming more widespread. The clouds and moisture will help keep temperatures a few degrees cooler with highs in the mid-80s and humidity values around 25%. These conditions are an improvement from the recent persistent hot and dry weather pattern and will assist fire crews in increasing containment of the fire in the coming days.
Yesterday, the helitack crew using “coyote tactics” were extracted from the north flank, where the fire is holding along the South Fork Merced River. Coyote tactics are used when crews sleep out near the fire's edge along remote portions of the fire and are logistically supported by helicopters. This helps limit exposure being transported in and out of the fire each day and increases the efficiency of their operations. Most of the heat left across the fire is smoldering logs well within the containment lines. Fire crews continue to coordinate with local agency Resource Advisors to ensure impacts that occurred during suppression efforts are repaired where possible.
Oak Fire- The Oak Fire is now 26 % contained at 18,087 acres. This fire is currently burning west of Yosemite in the Mariposa/Midpines area, and has caused the closure of Highway 140 west of Mariposa.
