Nebraska is sending staff from the state emergency management agency and two National Guard helicopters to help firefighters with two wildfires burning in Dawes County in western Nebraska.

The U.S. Forest Service says both fires were started by lightning from a thunderstorm on Tuesday, and are burning on public and privately owned lands.

One fire is between Harrison and Crawford and has burned about 250 acres of timber in rough canyons and inaccessible areas. There are three homes in the area, but no evacuations have been ordered.

The other fire is about 15 miles southeast of Crawford and has burned about 150 acres in rough timber areas with rugged canyons and grass.

No injuries are reported.
