COCORAHS CELEBRATES 25 YEARS DURING 2023

CoCoRaHS officially began on June 17, 1998.  With a few observers along Colorado's Front Range, we had no idea that the network would become what it is today, with over 26,000 active observers in the United States, Canada, Puerto Rico, the U.S. Virgin Islands, Guam and the Bahamas. A truly remarkable effort by all of you.  Please join us as we celebrate twenty-five years all summer long.  Here's to many more on the horizon.

The saying "Rain doesn’t fall the same on all" really proves to be true. How often have you seen it rain in your neighborhood and a few blocks away not a drop has fallen.

If you get the chance, please take a moment to tell a friend or neighbor about this exciting grassroots effort of citizens measuring precipitation right in their own backyards.  It's easy to join, takes only five minutes a day and is a fun way to learn about this wonderful natural resource that falls from the sky.  Your observations continue to give scientists an ever clearer picture of where and how much precipitation falls throughout our communities.

ABOUT  COCORAHS
CoCoRaHS (pronounced KO-ko-rozz) is a grassroots volunteer network of backyard weather observers of all ages and backgrounds working together to measure and map precipitation (rain, hail and snow) in their local communities. By using low-cost measurement tools, stressing training and education, and utilizing an interactive Web-site, our aim is to provide the highest quality data for natural resource, education and research applications. The only requirements to join are an enthusiasm for watching and reporting weather conditions and a desire to learn more about how weather can affect and impact our lives.

Our Web page provides the ability for our observers to see their observations mapped out in "real time", as well as providing a wealth of information for our data users.
