The Latest on wildfires burning in the West (all times local):

9 a.m. MDT

A dry thunderstorm moved over a wildfire near the Colorado-Wyoming border, but it had little impact where firefighters have battled the blaze to a standstill at 8 square miles.

Fire crews are focusing on protecting buildings and reducing the risk of the fire spreading in an area of heavy timber with a high percentage of beetle kill, and in some areas of grass and sagebrush.

Officials say 40 residences or cabins remain at risk. So far, only a few structures have burned.

Helicopters were used on the fire Friday, but the weather prevented airplanes from making air drops.

Officials are worried that thunderstorms expected this weekend could bring winds that spread the flames.
