Mountain Rain or Snow Volunteers Broke Records This Winter

The Mountain Rain or Snow project asks volunteers to track rain, snow, and mixed precipitation all winter long—and this was a winter like no other! This season, 1,684 people submitted precipitation observations—that’s about a third more than last season. These volunteers submitted over 32,110 observations, breaking last year's record by over 10,000.

Some observers excelled by sending in hundreds of observations---Patrick Thorson submitted 676! Nayoung Hur’s observations spanned the largest elevational range, and Lauren H’s came from the highest peak at 11, 993 feet.

Congratulations to Patrick Thorson, Chris Gotschalk, SV, Karen O, Marley Jennings, Mariah Blackhorse, Robert R., Randall Bursk, Bill Locke, Erin Grogan, Lauren H., Craig Hall, and Nayoung Hur for their remarkable contributions. Thank you to all Mountain Rain or Snow observers for keeping your eyes on the sky with us this winter!

The Mountain Rain or Snow project still needs more data to improve weather and water sources forecasting.If you are in the U.S.A. and you are on or near a mountain,  visit www.rainorsnow.org/signup on your phone and select your region to join the project!
