Do you ever wonder how much rainfall you received from a recent thunderstorm? How about snowfall during a winter storm? If so, then a new volunteer weather observing program needs your help! The Community Collaborative Rain, Hail, and Snow network, or CoCoRaHS, is looking for new volunteers across North Carolina. The grassroots effort is part of a growing national network of homebased and amateur rain spotters with a goal of providing a high density precipitation network that will supplement existing observations.
CoCoRaHS came about as a result of a devastating flash flood that hit Fort Collins, Colorado, in July 1997. A local severe thunderstorm dumped over a foot of rain in several hours while other portions of the city had only modest rainfall. The ensuing flood caught many by surprise and caused $200 million in damages. CoCoRaHS was born in 1998 with the intent of doing a better job of mapping and reporting intense storms. As more volunteers participated, rain, hail, and snow maps were produced for every storm showing fascinating local patterns that were of great interest to scientists and the public.
