The Cougar Creek Fire north of Glenwood grew by 700 acres on Thursday to 24,600, and remains at 20 percent containment.  Strong winds have move through the fire area for the last two days.  Crews held established control lines along the south and east flanks of the fire.    There has been minimal spotting due to the wind, and crews were able to hold the fire within its perimeter.  Burnout operations assisted in securing fire line around the fire contributing to the increase in reported fire size.  Winds helped firefighters on the northeast flank of the fire by pushing the fire back toward the interior.  Gusty winds increased fire activity on the west flank of the fire.  Crews were successful in completing line construction to Hellroaring Creek on the northwest portion of the fire line.  A National Weather Service Red Flag Warning remains in effect until Friday at 11:00 p.m.  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.
