A fast-growing wildfire that broke out Tuesday afternoon in the Ochoco National Forest has now burned more than 1,600 acres.

The Marks Creek Fire, about 20 miles northeast of Prineville, was 0% contained as of Wednesday afternoon.

The fast-growing wildfire prompted Crook County officials to issue multiple evacuation notices for areas surrounding the fire.

Officials are asking people to avoid the area, as crews work to establish and strengthen control lines. The Central Oregon Type 3 Incident Management Team took command of the fire Wednesday morning.

Fire officials said weather conditions are expected to remain hot and dry Wednesday, with potential thunderstorms rolling through. The storms could bring gusty winds and increase the area’s fire risks.
