A severe thunderstorm watch is in effect for northeast Nebraska, including Burt, Cuming, Madison, Stanton, Thurston and Wayne counties, and parts of northwest Iowa, including Monona County, until 3 p.m. Saturday.
Authorities in northwest Iowa say they have arrested a man after he made a threat on Facebook about shooting people.
The Sioux City Journal reports the Sioux County Sheriff's Office arrested the man Monday afternoon after receiving a report that he had threatened to shoot people in Hospers, which is located about 50 miles north of Sioux City.
The threat caused a precautionary lockdown of schools in the MOC-Floyd Valley school district. It was lifted less than an hour later.
Authorities have not released the man's name.
