EADS, Colo. (AP) -- Authorities say at least seven homes and a hog farm were destroyed after rare nighttime tornadoes ripped through sparsely populated counties on the southeastern Colorado plains.

No deaths have been reported, only minor injuries.

Authorities say the twisters were reported early Friday in Prowers, Kiowa and Bent counties, where the homes were destroyed.

State emergency management division spokeswoman Micki Trost says a hog farm in Prowers County was also destroyed.

The National Weather Service says preliminary findings indicate five tornadoes touched down. Two were in Prowers County, two in Kiowa County and one in Bent County.

Overnight tornadoes are rare in Colorado, where cooler nighttime temperatures usually don't create severe weather.
