About the Game

For anyone who takes mountain pursuits seriously, having accurate and timely snow information is not a luxury, it is a necessity. OpenSnow was built specifically to address this need, combining professional-grade weather forecasting technology with locally written analysis to give skiers and snowboarders a genuine edge when planning their next outing. Unlike generic weather platforms that treat all terrain the same way, OpenSnow focuses exclusively on mountain conditions, which means every data point and every forecast is relevant to what you actually care about.
At the heart of the platform is a team of regional forecasters who write a new Daily Snow update every single day. These are not automated reports pulled from a generic weather model. They are written by people who understand local mountain weather patterns, who know which storms tend to stall, which ridgelines catch the most snow, and how conditions evolve throughout a season. Subscribers can read these forecasts without limits and even receive them by email, so the latest information reaches you before you even open the app.
Beyond the written analysis, OpenSnow delivers a comprehensive set of forecast and reporting tools:
10-day snow forecasts for ski resorts across the US and Canada
5-day hourly forecasts with granular detail
Estimated 24-hour snowfall reports and rolling season-to-date totals
Snow depth mapping across mountain regions
Current and forecast radar with animated 2-day overlays
High-resolution maps for cloud cover, wind gusts, temperature, and wildfire smoke
Real-time lightning tracking and air quality monitoring
Avalanche forecast data and a 7-day conditions history
Snowpack graphs and long-term analysis tools
Mountain webcams with timelapse support
Offline trail maps you can save in advance
Custom alerts for snow forecasts and storm reports
One feature that stands out for those deciding between multiple destinations is the resort comparison tool. Instead of checking each mountain individually, you can pull up your favorite locations on a single screen and compare forecasts, current conditions, and live camera feeds at a glance. This kind of side-by-side view saves significant time during the decision-making process and reduces the chance of showing up to a resort that got less snow than you expected.
New users can explore everything OpenSnow All-Access offers through a 14-day free trial that requires no credit card. If you decide not to continue after the trial, your account simply rolls back to the free tier, which still includes storm update emails and access to limited forecast and report data. There is no risk involved in testing the full feature set.
Running OpenSnow through MuMuPlayer on your PC brings these tools into a desktop environment where maps, graphs, and written forecasts are easier to absorb at a glance. The expanded screen space makes animated overlays more readable and gives you room to study multiple data layers without feeling cramped. For dedicated powder hunters who treat storm research as seriously as the ski day itself, having OpenSnow on a big screen through MuMuPlayer is a practical upgrade worth considering.
