Heavy Rain in West Central Minnesota:

Street flooding was reported in Wahpeton, North Dakota, just across the border from Breckenridge. 2.75 inches fell in two hours at Wahpeton. Fargo received 3.45 inches for a storm total. Some of the higher rainfall totals found in Minnesota were 4.30 inches in Breckenridge. 2.79 inches at Sabin, 2.70 inches fell at Wheaton and 2.39 inches fell at Detroit Lakes.
