Weather Observers Wanted - Join CoCoRaHS!

CoCoRaHS is the Community Collaborative Rain, Hail, & Snow Network, a group of over 25,000 volunteer weather observers nationwide. CoCoRaHS observers measure precipitation (rain, hail, and snow) that falls at their location, and share their observations online. Every March, CoCoRaHS has an annual recruitment campaign to add more observers to the network.

Reports from CoCoRaHS observers are used by many organizations at the local, state and national level, including the National Weather Service. By volunteering as an observer, you play an important role in documenting how the weather affects your community.

All you need to report precipitation for CoCoRaHS is a standard 4 inch diameter rain gauge (shown in the photo above), and internet access to relay reports via the CoCoRaHS app or website.

You can report daily, during the rain or snow season, or whenever you are available to take measurements. It's up to you! We are simply grateful for any reports you can share.
