Torrential rainfall struck southern Minnesota on Saturday, unleashing severe flooding, closing major highways, and forcing emergency evacuations across multiple counties following overnight storms. The National Weather Service recorded precipitation totals exceeding seven inches in localized bands, with Lanesboro receiving seven point seven one inches and Ellendale recording seven point two nine inches. Heavy downpours concentrated along Interstate ninety impacted Waseca, Steele, Mower, and Freeborn counties. In Fillmore County, Spring Valley Mayor Justin Mlinar reported all municipal streets closed due to rising floodwaters. State Highway sixteen east of Lanesboro closed after a saturated hillside collapsed, sending mud and debris across the roadway. Minnesota Department of Transportation crews deployed heavy equipment to clear obstructions. Rising river levels triggered severe flood warnings, with the Cedar River near Lansing reaching eighteen feet and projected to crest higher. Emergency management officials urged residents to avoid flooded roadways as ongoing recovery operations remain strictly underway today.
