A fast moving forest fire near Satus Pass had burned an estimated 1,100 acres and prompted a mandatory evacuation of almost 40 homes by late Wednesday evening.
Another 21 homes were on the alert for evacuation, reports the Klickitat County Sherriff's Office.
About 100 firefighters from the state Department of Natural Resources and Klickitat County fire districts were working on the fire, aided by retardant-dropping aircraft.
A strike team and engines from Benton fire districts 1, 2 and 4, Franklin Fire District 3, Walla Walla fire districts 4 and 5 are leaving at 4 a.m. today to help fight the fire, according to Benton Fire District 1.
The fire, which shut down Highway 97 between Toppenish and Goldendale for several hours in the afternoon, is among the largest forest fire to strike southcentral Washington this year.
