National Weather Service United States Department of Commerce


Do you have an interest in observing and recording rain and snow across southeast Minnesota, northeast Iowa, or western and central Wisconsin? If so, we are always looking for weather observers, and the Community Collaborative Rain, Hail and Snow Network (CoCoRaHS for short) is a simple and free-to-join way to allow you to report rain and snow amounts, while also allowing us at the National Weather Service to access your reported weather information.

Read more in the tabs below, and if you have any questions, please feel free to contact David Lawrence and Jeff Boyne. We would love to have you as an observer.
