WANAMINGO, Minn. (AP) – Powerful thunderstorms slammed the Upper Midwest and caused heavy flooding, leaving one man missing in Minnesota, destroying a small-town city hall in South Dakota and forcing several people out of their homes.

The National Weather Service predicted that more thunderstorms were likely Wednesday evening in parts of Minnesota and Wisconsin.

Those storms could contain large hail and damaging winds, the weather service said.

Jeffrey S. Zelinske, 47, remained missing Wednesday. He was headed to work when a creek surged over its banks and flooded the road with up to 2 feet of water. His empty pickup truck was found in a rain-swollen ditch near Wanamingo.

Another woman survived after her car was swept up in a flash flood by floating on her back and grabbing onto a fence post.

“I call it a God-wink miracle,” said Mona Boomgaarden, 50, who added that she does not know how to swim.

Wind gusted to 92 mph during the night in north-central South Dakota, destroying the one-story city hall in Onaka, flattening a farm cooperative building in Faulkton and damaging other buildings.

The new city hall was built after the previous building was destroyed by fire two years ago.

“We’ve lost everything, again – all of our financial records,” said Shannon Waldman, the town’s mayor of 20 years.

The National Weather Service said a tornado briefly touched down Tuesday in the southwest corner of South Dakota, damaging farm machinery. Hail nearly 3 inches in diameter was reported in Meade County.

About 30 people were forced out of their houses in Edgeley, N.D.

In the Twin Cities, lightning strikes were blamed for two fires.

The storm also knocked power out to more than 200,000 Xcel Energy customers in the Minneapolis metro area, and more than 63,500 customers were still without power Wednesday afternoon.
