Evacuation levels are going to remain in place in the area of the Microwave Tower Fire through the weekend.  Wasco County Sheriff Lane Magill said in a statement that after reviewing the current situation Friday morning, the decision was made based on the weekend weather forecast and ongoing activity of first responders within the fire perimeter.  Magill says he and fire command will reassess the situation on Monday.  The only remaining area on Level 2 is from Highway 30 south to Hood River Road, east to Rock Creek and Huskey Road, and west to the Hood River County line.  Other locations are in Level 1 and remain in that status.  Interior firing operations within the fire perimeter were successful on Thursday, and along with continued mopping up along the fireline the containment level moved up to 84% today.  Fire size remains steady at 1,311 acres.  The fire line along the northeastern edge of the fire has been improved.  The Central Cascades Interagency Management Team says crews Friday were continuing to monitor the entire fire’s perimeter to ensure the continued security of lines, extinguishing hot spots where accessible, and working to increase containment from Old Highway 30 to Interstate 84.  With hot and dry conditions, residual pockets of vegetation will continue to burn producing visible smoke and potential flames.  Drivers are asked to use caution on Interstate 84 as firefighters are still working in the area.  The Columbia River Highway State Trail remains closed, and Elder Road has reopened to local traffic only.
