| Episode Narrative | A strong storm system, in combination with deep moisture from the remnants of a tropical system, produced a large area of flooding rainfall with amounts as high as 8 and 11 inches in an 18 hour period. The main area of precipitation occurred across far southern Minnesota, and portions of west central Wisconsin, between 7:00 p.m., Wednesday, September 22nd, to 9:00 a.m., Thursday, September 23rd. Some of the smaller rivers in southeast Minnesota had historical crests which caused extensive damage around Northfield, Cannon Falls, Zumbrota and Pine Island. One bridge section on the North Fork River along Highway 52 between Cannon Falls, and Pine Island collapsed. The bridge in Cannon Falls was inundated by the flood waters of the Cannon River. In addition to the smaller tributaries, the larger Minnesota and Mississippi Rivers had flooding from Redwood Falls, to the Twin Cities, then southeast to Red Wing, Minnesota for about two to three weeks, as the runoff was extensive. Some of the most notable rainfall measurements are as follows: It was a record 2-day rain event in Amboy, MN (10.68), Waseca, MN (7.65), and Springfield, MN (5.47). Thursday was also the wettest day on record in Waseca, MN (5.16). |
| Event Narrative | Bands of thunderstorms began to develop across the county by mid evening, with several thunderstorms training over the same areas. By midnight, nearly five inches of rain fell in the southwest corner around Willow Creek and Amboy. By morning, Amboy had nearly 9 inches of rainfall, with roads closed across the southern part of the county. In addition, several county roads and highways were closed or blocked by flood waters, including Highway 30 west of Mapleton, and Highway 30 east of Mapleton by County Road 14. Highway 66 south of Mankato also had water over the road. |
