Don't yell at the weatherman. Become one.

MIDDLETOWN — Join a nationwide group of 15,000 volunteers who report the daily weather in their own backyards.

CoCoRaHS — the Community Collaborative Rain, Hail, and Snow Network — is supported by the National Oceanic and Atmospheric Administration, the National Science Foundation, and other sources, but depends on volunteers. All they need is Internet access and an inexpensive rain gauge.

A free training session for volunteers will be held from 1:30 to 3:30 p.m. on Saturday, May 5, at the Gander Mountain store, 100 North Galleria Drive, in Middletown.

Space is limited, and pre-registration is required.

For more information or to register call 644-4356 or email CoCoRaHS@Cornell.edu.
