The prevailing winds will be out of the west-southwest
A very persistent warm and dry weather pattern continues to support the potential of active-to-very active fire behavior today. Primary area of fire behavior focus includes the S. Fk. Merced River upstream to the Iron Cr. and Johnson Cr. areas where most of the current activity is occurring.
24 hours: Continuation of warm/dry weather will produce the potential for active fire behavior during the period, with the burning conditions extending into the evening due to poor relative humidity recovery on higher terrain. Generally light winds will produce pockets of isolated backing on slopes with flanking, and isolated torching within the control lines. Southwesterly ridgetop winds will provide clear sky and good ventilation. Continued potential for spotting north of the South Fork Merced River in the Johnson Creek area, and across Iron Cr. to the east as the fire consumes residual fuels near the containment lines.
