Washburn Fire Update- One of the main indicators of seasonal fire danger is an index called the Energy Release Component. The extended drought conditions and very dry airmass over the area yesterday resulted in the highest Energy Release Component rating ever recorded for the Central Sierra Predicted Service Area. These conditions were the cause for rapid rates of spread when the Oak Fire ignited on Friday. The Oak Fire is burning approximately 12-miles west of the Washburn fire. Coordination is occurring between fire managers and both air and ground resources responded from the Washburn Fire to assist in the suppression efforts occurring on the Oak Fire.  

Today, resources on the Washburn Fire will continue to actively secure the remaining portions of heat near control lines. The two main areas of focus are near the confluence of the South Fork Merced River and Iron Creek. Crews are coordinating with pilots using Unmanned Aircraft Systems (UAS) containing an infrared camera to provide accurate information on the hotspots burning in the remote and rugged terrain. The predicted southwest winds will transport most of the smoke generated from the Oak Fire plume to the north, but smoke and haze will linger over the Washburn Fire today. Conditions will remain warm and dry with temperatures in the mid 80’s and minimum humidity around 15%. Information for the Oak Fire can be found at or by calling 844-MMU-FIRE (844-668-3473). The Oak Fire started on Friday, July 22nd at Highway 140 and Carstens Road, near Midpines, CA (outside of Yosemite National Park boundaries).  The Oak Fire currently sits at 14,281 acres and is 0% contained. Highway 140 and surrounding roads have closures in effect.  

Wawona Road (Highway 41) has reopened as of 6:00 am on Saturday, July 23.
