COCORAHS NOW IN ALL 50 STATES (as well as the District of Columbia)
The saying "Rain doesn’t fall the same on all" really proves to be true. CoCoRaHS has expanded across the country at a rapid pace over the past few years.  With the addition of Minnesota to the network in December 2009, CoCoRaHS is now in all fifty states.  When you have the chance please tell a friend or neighbor about this exciting grassroots effort to measure precipitation in the backyards of citizens from the Atlantic to the Pacific.  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.  We are striving to have 20,000 active observers by the end of 2010.


ABOUT  COCORAHS
CoCoRaHS 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 effect 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.
