(AP) — Local flooding and washed-out roads have prompted travel warnings from Kimball County officials.

County highway superintendent Dave Hottell blames the mess on runoff from melting snow in the southern Nebraska Panhandle county and adjacent parts of Wyoming. He says roughly half of his county’s gravel roads are washed out “and the other half are not in good shape.”

Some stretches of U.S. Highway 30 have been closed as well because of local flooding.

The U.S. Geological Survey says a gauge in the county’s Lodgepole Creek has recorded its highest flows in more than 30 years.

Banner County and Sioux County officials have issued travel advisories for their county roads, too.
