The intense rainfall has resulted in multiple reports of flooding across southeastern Minnesota, with several rivers continuing to rise following the deluge. The Root River in Houston County is projected to rise above 15 feet, reaching minor flood stage, while the Cedar River near Lansing in Mower County has already reached 18 feet. With additional runoff still making its way into area waterways, river levels are expected to remain elevated and could continue rising through the weekend.
