Anticipating the arrival of a gusty cold front Wednesday, Cougar Creek Fire crews will continue to reinforce the fire lines along the west and south flanks and to burn out fuel on the east flank.  The National Weather Service has issued a Red Flag Warning beginning Wednesday afternoon through Friday, with strong winds combined with low relative humidity and high temperatures mixing to increase fire activity.  Beginning Wednesday afternoon, winds are expected to gust up to 35 miles per hour and last through Thursday evening.  Crews will pay special attention to look out for wind-driven spotting fires outside the line.  Contingency structure protection plans have been developed in the unlikely event wind pushes the fire beyond its current boundaries.  In its ninth day Tuesday, the fire increased 500 acres to a total of 23,100 acres.  Crews have contained 20 percent of the fire line.  The increased size was from burnout work.  Residents of Glenwood north of Ladiges Road remain under a Level 1 evacuation advisory from the Klickitat County Sheriff’s Office, advising residents to be alert of the fire’s activity.
