NEW ULM — A burst of strong winds has damaged dozens of vehicles at a south-central Minnesota car dealership.

Winds and heavy rain ripped through Kohls-Weelborg Chevrolet in New Ulm around 4:30 p.m. Wednesday.

General manager Doug Schablin said the storm hit without warning. He said the rain and wind “turned everything white.”

Within 20-30 seconds, Schablin said it was over. He said the wind blew out the windows of 70 vehicles and bent flagpoles at the dealership to the ground.

The National Weather Service reported winds at the airport were clocked at 75 mph.

A Brown County sheriff’s dispatcher said trees and signs are down in New Ulm, but no injuries were reported.

Much of central and northern Minnesota and parts of southern Minnesota were under flash flood watches until today.
