UNDATED (AP) - A weather system that's triggered thunderstorms and spawned tornadoes in the nation's midsection is weakening but the threat of wicked weather remains for some areas.
Storms sweeping across central and southern Minnesota Sunday have dumped heavy rain and hail but caused no major damage.
The National Weather Service says three tornadoes were spotted in two Minnesota counties but no damage or injuries are reported.
Meanwhile, residents in western Oklahoma and Iowa are sifting through the wreckage of their homes after overnight tornadoes crashed into several communities.
In the western Iowa town of Thurman, piles of toppled trees lined the streets in front of homes with missing walls and roofs. No serious injuries were reported.
But five people were killed, three of them children, when an overnight tornado ripped through a mobile home park in Woodward in northwestern Oklahoma. Dozens more were injured. The town manager says 89 homes and 13 businesses were destroyed.
Oklahoma Gov. Mary Fallin toured the town Sunday.
