The strong winds across southern Minnesota on Wednesday are being blamed for a semi rollover near Worthington Wednesday evening. It happened at just after 5:30pm on the Highway 60 detour just south of Worthington. 64-year-old Stephen Ahlers of Slayton was driving a Peterbilt tractor-trailer loaded with hay bales southbound when the wind caused the vehicle to roll while Ahlers was negotiating a right curve. He suffered only minor injuries, and was treated at the scene. The truck took moderate damage.
