NEWCASTLE, Wyo. (AP) — More rain is expected to help firefighters at the 17-square-mile Squirrel Creek fire but winds from thunderstorms have helped spread the fire a bit.

The fire about 30 miles southwest of Laramie grew by about 650 acres before some rain began falling Thursday. The fire was 55 percent contained Friday.

Authorities say the fire was human-caused and remains under investigation.

Air Force C-130 cargo planes have been used to drop slurry on the blaze, which has destroyed one home and three outbuildings.

Crews continue to fight the 91-square-mile Oil Creek fire in northeastern Wyoming and the Fontennelle fire in the Bridger-Teton National Forest. Light rain also fell at the Fontennelle fire but fire managers say it wasn’t enough to change fire conditions there.
