The Community Collaborative Rain, Hail and Snow Network (CoCoRaHS) organizes volunteers in communities throughout the United States to collect and measure precipitation — rain, hail and snow — in their communities. Citizen volunteers are trained how to measure precipitation using a rain gauge and hail pad, record their data and report their measurements online. Data collected by volunteers complements observations made by the National Weather Service and is used by local meteorologists, researchers, emergency managers, farmers, outdoor enthusiasts, teachers and others. Help weather experts keep track of where and how much it rains in your neighborhood by volunteering to be a “data collector” for the Community Collaborative Rain, Hail and Snow Network.

An excellent example of CoCoRaHS in action is from our flooding May 12, 2012. A network observer recorded 11.19 inches of rainfall overnight Friday into Saturday morning in Pecan grove. The flood control district inspected the gauge and its surroundings to determine the validity of the report. It checked out and another station Pecan Grove recorded 10.70 inches. Without these observations we would have had to rely on radar estimates which were only showing 7"-8" of rain.
