OMAHA, Neb. (AP) — Nebraska’s 3rd House District congressman says he’s ready to respond to any requests for federal assistance to help contain several wildfires in his vast, rural district.

Rep. Adrian Smith says any Nebraskans in need of help can contact his Grand Island office.

Smith’s statement came as wildfires burning in north-central Nebraska threatened to force the evacuation of the small town of Sparks.

On Tuesday, the main Fairfield Creek fire expanded to about 92 square miles — an area just bigger than the state capital of Lincoln. Two other smaller fires about 20 miles to the east had burned more than six square miles.

The fires have destroyed at least 10 homes. A cold front expected to move in the area Wednesday could provide some relief.
