PORTLAND, Ore. (KOIN) — A wildfire on the north end of the Warm Springs Reservation has grown to about 4,300 acres after sparking around 6 p.m. Friday.

The S-503 Fire, about 3 miles east of Hwy 26 and 10 miles north of Simnasho, brought multiple agencies to the front. The hot, dry conditions and gusty winds are expected to be a factor in fighting this fire, the CTWS fire management said on their Facebook page.

As of Sunday, the blaze was 0% contained.
