During winter storms, tell us what is falling from the sky.
It is notoriously difficult to research winter precipitation in the mountains because it can vary over the course of minutes and across short distances.
Scientists need real-time help tracking changes between rain, snow, and mixed precipitation.
You can submit valuable weather observations in just a few seconds through the Mountain Rain or Snow app.
How to get started
Sign up for weather text alerts by sending the correct keyword for your region (shown below) to 855-909-0798.
Log in to the web app to start sharing your local weather observations with scientists.
Every report you send adds to a growing dataset that helps researchers understand how precipitation changes across different elevations, regions, and seasons. These data are used by:
Scientists studying climate and weather patterns
Meteorologists refining precipitation models
Agencies improving winter storm forecasting
Educators introducing real-world science to classrooms
