March Madness 2013 underway. Encourage a friend, family member, co-worker, or neighbor to sign up for CoCoRaHS and help Oregon win the title!

How do I join:
It's easy to sign-up to become an observer - click on "Join CoCoRaHS" and complete the on-line application form. Once you sign up, you will receive a login and password. After you have a rain gauge and begin making observations, you can log in and report them. Your precipitation observations will start showing up daily on our county maps.

What do I need:
Besides a desire to observe and record the weather, the only thing you will need is a standard 4" rain gauge.  We strongly encourage you to purchase one of these 4" rain gauges. This will ensure that the data collected by CoCoRaHS observers is not only consistent throughout Oregon, but between Oregon and the other states that participate in the program! The rain gauge will cost you $30, plus $9 for shipping, and may be purchased at WeatherYourWay.com or AmbientWeather.com.

NOTE:Several people have asked about the possibility of buying the rain gauge from a local vendor. Unfortunately, after several hours of checking, there are no such local vendors.
