(FOX 9) - Flash flood warnings were issued across southern Minnesota and western Wisconsin Monday morning after a deluge Sunday night left some areas with radar-estimated localized amounts of 7 or 8 inches of rain and more than 9 inches in Glenwood City, Wisconsin.
A flash flood watch was issued for a large swath of the greater Twin Cities area until noon Monday after the heavy rain. For perspective, the MSP Aiport yearly average is near 4 inches for the entire month of June. Last year, the airport received just 2.72 inches for the month. The highest June rain since 1900 was 11.36 inches in 2014.
