As firefighters across the West responded to blazes, efforts in Washington state were made especially difficult Tuesday as wind gusts pushed fast-moving flames through a small town, destroying dozens of houses.

The fire in central Washington has burned about 70 homes, scorching along roughly 40 square miles of grassland, timber and sagebrush, authorities said.

More than 400 people have been evacuated, said Department of Natural Resources Fire Incident Commander Rex Reed. No injuries have been reported, but authorities say that because of wind, heat and dry conditions, the fire danger is extreme.

“We’ve had a long prolonged dry period — three weeks with no precipitation at all,” Reed said.
