Cooler temperatures minimized fire growth Sunday on the Bull Complex Fire in the Mt. Hood National Forest, and unseasonably cooler temperatures were forecast to remain over the fire area again Monday.  Fire officials say temperatures are expected to increase and normalize starting Tuesday, possibly increasing fire behavior and visible smoke.  The fire is still smoldering, moving along the ground and burning in low brushes and small trees.  Firefighters are working to remove vegetation with heavy equipment and chainsaws to prepare existing roads to use as containment lines.  If conditions are appropriate firefighters may do burnouts along those roads to remove fuel between the roads and main fire to slow the main fire’s progress towards the desired containment lines.  Pumps and hoses are also being installed to support potential future burnouts.  The south end of the fire, closest to Detroit and the Breitenbush Hot Springs, is the current priority containment focus area.
