Flooding & Severe Weather July 14-15, 2021

Several rounds of showers and thunderstorms cross northeast Wisconsin the Wednesday afternoon, July 14 and continued into the early morning hours of Thursday, July 15.


The first round of thunderstorms produced isolated damaging wind gusts late in the afternoon over east-central Wisconsin.  Several downed trees were reported over the northwest portion of Manitowoc county shortly after 4 pm.  However, the most significant impacts revolved around heavy rainfall and flooding.  Thunderstorms trained over the area from Waushara and Waupaca to Manitowoc and Two Rivers late in the evening into the overnight hours. 


The end result was a swath of heavy rainfall in the range of 3 to 6 inches in that area.  The highest rainfall were reported from Whitelaw in Manitowoc county (5.38 inches), Two Rivers (4.90 inches), and Manitowoc (4.83 inches).  The heavy rainfall created flooded roads, parking lots, and basements, caused the Manitowoc River to overflow its banks.
