Interested In Being A Volunteer Weather Observer? Join CoCoRaHS!

Do you have an interest in observing rain, snow or hail? After this winter, you may say "no" to the snow part of it, but this information is a key component to knowing how much precipitation has fallen. The CoCoRaHS (Community Collaborative Rain, Hail, & Snow) network was established after 1997 flash flood that occurred near Bolder, Colorado - the local meteorologists wanted to have more forewarning of flood conditions. The CoCoRaHS program has since spread through the rest of the country (even Canada).

The only requirements for the program is that you purchase your own rain gauge (approximately $30 - we can direct you where to get an official CoCoRaHS gauge), that you go through some training, and have an interest in observing precipitation. We are planning training sessions, but if you want to get started now, you can go to and click on the "Join CoCoRaHS" button. The NWS La Crosse is looking to expand its current network of observers and would love to have you on board. 

If you have any questions about the program, please contact Tim Halbach at
