Overview
|
For multiple days, the region was in a heavy rainfall pattern that brought waves of showers and storms to the Upper Mississippi River Valley. Amazingly, Mother Nature hit different areas each day with heavy rain swaths, lessoning the impact somewhat. These swaths can be seen in the multi-day rainfall graphic to the right. The most significant flooding came on the last day (Monday, August 18) in the pattern from the very early morning into the afternoon. A band of 3 to 6 inches of rain fell from about Decorah to Charles City, Iowa. Many area rivers rose into minor flood stage with the worst flooding on the upper reaches of the Turkey river drainage and the Upper Iowa river. The cooperative observer in Decorah, IA measured 8.64" between 5 PM on August 17 and 5 PM August 18. This was their wettest August and wettest day. Previous record was 8.06" on August 23-24, 2016. They have been taking daily precipitation records since 1893. The greatest rainfall during this period was in Decorah, IA with a total of 12.54". |
