SIOUX FALLS, S.D. (AP) — More than half a foot of rain in parts of Sioux Falls led to flash flooding that inundated basements and stranded dozens of motorists.

Mayor Mike Huether called it a "100-year rain."

No injuries were immediately reported after the flooding Thursday evening, but there were several reports of damaged structures. More than 4,000 Xcel Energy customers lost power during the storm.

Danny Sullivan and his family were among the motorists who got caught up in high water. He tells the Argus Leader that their vehicle became submerged and they had to climb out the sunroof. He says he's grateful no one was hurt.

The Red Cross deployed volunteers during the flooding and opened a shelter for people who were displaced.
