Firefighters are working round the clock under extreme fire behavior conditions to stay ahead of the Cable Crossing Fire east of Roseburg off Hwy 138E. Following two consecutive days of Red Flag Warning weather, that brings high temperatures, low humidity and gusty winds, the fire has grown to 830 acres. Containment is estimated at 15 percent. Supported by a host of helicopters, retardant dropping air tankers, bulldozers and engines, fire crews made considerable progress under extreme temperatures. Objectives were accomplished by holding established containment lines on the north and west end of the fire. With the fire pushing to the south and east, crews kept up with spot fires before they could gain any momentum. The day shift set a nice table for crews working through the night when the fire activity is expected to subside under cooler conditions. The Red Flag Warning is predicted to stay in place through the weekend with a chance of thunderstorms arriving Friday.
