There is always a need for a greater number of observations, as the saying goes "the rain doesn't fall the same on all".  Due to the variability of precipitation, amounts measured can be quite different only a block or two away.  Would you consider helping fill in the gaps?  The more observations, the clearer the picture, the better the understanding of where it did and did not rain. Not only that, you as an observer play a pivotal role in providing accurate high-quality precipitation data for our many users including the National Weather Service, other meteorologists, hydrologists, emergency managers, city utilities (water supply, water conservation, storm water), insurance adjusters, USDA, engineers, mosquito control, ranchers and farmers, outdoor & recreation interests, teachers, students, and neighbors in the community.

CoCoRaHS, (Community Collaborative Rain Hail and Snow) network is the platform where you can join. You may ask, who can join? It's a community project. Everyone. It's both fun, educational, and rewarding. To find out more information about CoCoRaHS, refer to the link => It's free to join with the only one time cost being the required rain gauge.  

The following pictures show a national and close-up perspective on the visualization of observer data and just how important it is to not only know where and how much precipitation fell but where it did not, which is equally important. We need you and look forward to you becoming a part of the CoCoRaHS family of volunteers working together to measure precipitation.
