Firefighters anticipate dry, gusty winds Friday, following days of hot and arid weather, will worsen the spread of the Miriam Fire, which was at more than 1,900 acres Thursday.
Possible thunderstorms could ignite more fires. Lightning from a Saturday thunderstorm sparked a 5-acre fire near White Pass, which is burning slowly in the area around Shoe Lake, Clear Fork and Pacific Crest trails in the Gifford Pinchot National Forest.
The Clear Fork Fire was discovered Wednesday and will be managed by Miriam Fire personnel.
Winds are expected to be 15 to 25 mph with gusts up to 35 mph.
The fire was at least 9 percent contained Thursday and about 344 people were on scene, including six 20-person crews, three helicopters, 25 engines and two bulldozers.
