PAYSON, Arizona — Crews on the ground and in the air are making progress against the Washington Fire, which had burned an estimated 550 acres about 11 miles north of Payson. The lightning-caused blaze, which started Aug. 13, was 6% contained with nearly 500 personnel assigned as of Sunday. Firefighters are working to keep the fire boxed in between the Highline Trail to the south and Forest Road 300 to the north, while strengthening handlines and contingency lines around threatened communities and cabins. Officials say a combination of dozer work, hose lays, handlines and aerial water drops helped slow the spread and protect structures on the fire’s edge. …Dry, hot weather is expected to challenge suppression efforts in the days ahead, with firefighters also on alert for new starts. …Evacuation orders remain in place for Mountain Ridge Cabins, Washington Park and Shadow Rim Ranch.
