Fire activity has continued to decrease on the Dry Creek Fire north of BZ Corners, and the Klickitat County Sheriff’s Office announced a change in evacuation advisories.  All Level 2 Evacuation notices, have been reduced to Level 1, which advises people to be ready for a potential evacuation.  All Level 1 Evacuation notices remain in effect.  An update from fire officials today showed the amount of acreage burned remained at 322, with the containment level moved up to 28 percent.  Crews are looking to establish a buffer of reduced fuels, either completely consumed or extinguished, within the containment lines to reasonably assure the fire will not escape.  With a warming trend expected to continue through the weekend, fire managers are pressing to complete mop up and secure the lines before conditions become more unfavorable, but are also increasingly confident that they will meet that goal.  There are 544 people assigned to the fire.  Highway 141 reopened on Tuesday, with a pilot car escorting traffic through the fire area.  The cause of the fire remains under investigation.
