PORTLAND, Ore. (KOIN) — As temperatures begin to increase and dry conditions continue, fire crews are hastily working on suppressing the S-503 Fire on the Warm Springs Reservation.

Aerial infrared technology has given officials a more accurate estimate of acreage burning, which is now reported to be 6,679 acres or just over 10 square miles. As of 9 p.m. Wednesday it was 30% contained.

The S-503 Fire is about 2 miles east of Hwy 26 and 7 miles northeast of Simnasho. The hot, dry conditions and relatively low humidity have been a factor in fighting this fire — but officials say recent cooler weather allowed firefighters to make significant progress. Thankfully, there was no fire perimeter growth throughout Wednesday.
