Welcome to U.S. Virgin Islands CoCoRaHS!

Local Brochure: English Version - Spanish Version

U.S. Virgin Islands are delighted to be participating in the growing CoCoRaHS network. U.S. Virgin Islands (USVI) CoCoRaHS observers provide important information about rainfall that is used by meteorologists, hydrologists, farmers, water resource managers, and your friends and neighbors.

What are the benefits of being a CoCoRaHS observer? By participating in the CoCoRaHS network you will make an important contribution that helps others, especially during flood situations. By providing your daily rainfall data, you will also assist in filling in important pieces of the puzzle that will contribute to the knowledge of the Caribbean climate.

What do I need to participate? All that's needed to be a CoCoRaHS participant is the desire to watch and report weather conditions. You will need access to an internet-connected computer and the appropriate measurement tool; a 4" diameter plastic rain gauge. Here is list of vendors who carry the CoCoRaHS gauge. The gauge should cost around $33 plus shipping. They are usually shipped out right away so you can set up your gauge in a matter of days. The cost of a gauge hopefully will not stop you from joining.

How do I join? Signing up to become a CoCoRaHS observer is easy. Just click on the Join CoCoRaHS link and complete the application form. The application form will ask you for your station coordinates, which can be estimated from websites such as After applying, you will receive a username and password. Once you have a rain gauge, you can log in to report your observations, which will then begin appearing on the tables and maps!

Training is provided and required for CoCoRaHS observers. Training is available through written instructions or videos on the CoCoRaHS website or through your local commonwealth coordinators.  Announcements of training sessions will be made. Click below for online training.
