DES MOINES, Iowa (AP) — A band of storms produced some sightings of tornadoes in northwest Iowa Friday night, but there were no reports of injuries or significant damage. Kathy Stodola is duty officer for the Iowa emergency management department. She says that there was a report Friday evening of a roof torn off a building in Cherokee county.

The National Weather service says it received four reports of tornadoes, three in Sioux county and one in Cherokee county. Stodola said she expected the weather service to do an evaluation on the ground after daylight today (Saturday).
