June 17th -- CoCoRaHS Day! … Happy Twenty-first Anniversary!

Monday is CoCoRaHS Day. The CoCoRaHS website was launched June 17, 1998 -- officially marking the beginning of our volunteer rain gauge network. One hundred beginner weather observers reported that day. We now have over 21,000 rain gauge observers who send in reports regularly or occasionally. Let's celebrate our 21st anniversary with everyone sending in their CoCoRaHS daily precipitation reports and setting a new all-time record for most CoCoRaHS reports in one day. Let's aim for 14,000+ reports!

For those of you who did not know, the number of reports received each day is listed just above the national map on our home page.

Want to know more about the history of CoCoRaHS? Last year for the 20th Anniversary we ran a series of articles on the evolution of the network. The whole series can be found here: HISTORY.

Thanks very much for all of your reports and being part of our CoCoRaHS team!
