A wildfire that's been burning on the Okanogan-Wenatchee National Forest in Chelan County for over two weeks has now surpassed 50,000 acres. Over the weekend, the blaze spread rapidly in wind gusts of up to 50 mph under a Red Flag Warning, prompting new evacuations for the south side of Lake Chelan. Instead, crews using both fixed- and rotary-wing aircraft to perform strategic water drops in an effort to suppress the spot fire near the Safety Harbor Campground. In addition to the latest evacuations on either side of Lake Chelan, hundreds of residents also remain on evacuation notices in the Entiat Valley and near the Chiwawa River Drainage. Over 1,800 structures are currently being threatened by the blaze, but none have been damaged or destroyed.
