CoCoRaHS - The Community Collaborative Rain, Hail, and Snow Network

CoCoRaHS Logo

CoCoRaHS is a unique, non-profit, community-based network of volunteers of all ages and backgrounds working together to measure and map precipitation (rain, hail and snow).  The data is used by forecasters, researchers, drought assessors, and others.

The El Paso Area National Weather Service office is looking for volunteer rainfall observers across Southern New Mexico and Far West Texas.  All you need is a plastic rain gauge and an internet connection! 

Anyone can join, young or old, individuals or organizations. Current CoCoRaHS "stations" are located in urban/suburban backyards, farms, ranches, museums, and State Parks.
