Heavy overnight rainfall caused some mudslides and flooding along the Mississippi River in southeastern Minnesota.
A flood warning for the region is in effect for Saturday after some areas saw between 2 to 6 inches of rain.
Mudslides trapped a semitrailer on Highway 61 early Saturday, and temporarily closed the highway in Winona County, but that roadway and others had all reopened by later Saturday morning.
Michael Peterson of the Winona County Emergency Management tells the Star Tribune the shoulders of some county roads are damaged, and motorists should use caution, but he says flooding has subsided.
Public safety officials said lightning struck a power pole in Winona. The pole then crashed on three buildings and caught fire.
