Fire behavior increased on the north and northwest flanks of the Cougar Creek Fire on Sunday.  As forecasted, increased temperatures and low humidity contributed to fire spread as spot fires progressed into critically receptive fuels.  The fire north of Glenwood has burned 34,953 acres, with containment downgraded to 15 percent over the weekend.  Crews continue to strengthen and secure containment lines along the south and east portions of the fire.  An increased amount of smoke from the fire is expected today, as burnout operations will be conducted on the north end of the fire to attempt to slow progression to the north and northwest.  Inaccessible terrain, heavy dead and down fuels and indirect containment lines continue to pose a problem to firefighting personnel.  A community meeting is scheduled for Tuesday at 6:00 p.m. in the Glenwood School gymnasium.
