March is the month for annual recruiting efforts for the CoCoRaHS precipitation network, in an interstate competition dubbed “March Madness”.  North Carolina has one of the largest networks in the country, with over 900 active observers.  In this week’s blog, they discuss the history of CoCoRaHS and the variety of people who use the rain and snow information.  Come on, Southeast!  There are plenty of areas with no active observers yet, and we would love to have your observations added to the mix.
