About 1800 acres have burned so far in the Waterfall Fire on the Warm Springs Reservation.
Warm Springs Fire Management Officer Clay Penhollow says crews have done some "back burning" to prevent the fire from expanding to much more to the east.
He says this weekend is going to be challenging for them, because the weather forecast is for trouble. "The predictions were for lightning storms Friday, Saturday, Sunday. So we're kind of getting ready for that. We've called in a management team to take care of the fire so we can relieve our folks back to initial attack, to get ready for those lightning storms."
Penhollow says should the fire switch directions and threaten recreation areas, campers will be evacuated from the Mt. Hood area, but right now, it's burning in good timber areas.
