SnoTel Mapper
Track snow conditions, avalanche forecasts, and weather data from mountain stations across the western US and British Columbia
Track snow conditions, avalanche forecasts, and weather data from mountain stations across the western US and British Columbia
Access real-time and historical snow data from automated SNOTEL stations (NRCS) and partner networks such as BC snow pillows. Whether you're planning a backcountry adventure, monitoring avalanche conditions, or tracking winter weather patterns, SnoTel Mapper delivers the critical information you need to make informed decisions in the mountains.
Comprehensive tools for tracking mountain conditions
Browse SNOTEL, SNOW, SCAN, and BC snow pillow stations on topo and satellite maps. Search, cluster, and filter by network for quick navigation.
Charts for snow depth, temperature, and historical comparisons—plus optional metric units (°C / cm) so readings match how you travel. Share a station as a conditions card; BC cards are labeled BC data.
Save unlimited stations for quick access. Your top 3 favorites automatically preload for offline viewing. Compare them with Morning Brief (Pro). On Android, pin those three to a home widget; on iOS they appear on Apple Watch.
View avalanche forecast regions with current danger ratings. Direct links to detailed reports from regional avalanche centers.
Live precip radar, winter probabilities, snow accumulation, plus terrain context—aspect, hillshade, and slope.
Intelligent caching ensures your favorite stations remain accessible even without cell service in the backcountry.
Access years of measurements. US stations compare to 20-year snow-depth normals; BC snow pillows compare SWE to the period-of-record median and last year.
Choose light, dark, or 80s Neon, metric or imperial units, set custom map locations, and reorder data cards to match your workflow.
Get the latest measurements as soon as they're available from official NRCS and partner data sources.
On iOS, a native companion shows your top 3 favorites with snow depth, temperature, and 24h change—synced from the iPhone after favorites change and on hourly preload.

Direct access to USDA NRCS SNOTEL and BC Snow Survey / River Forecast Centre snow pillows (Open Government Licence – British Columbia)—the same networks used by avalanche forecasters and water managers.
Beautiful visualizations transform complex data into actionable information you can understand at a glance.
Zero personal data collection. Your location is used only for map centering and never stored or shared.
Regular updates bring new features, performance improvements, and enhancements based on user feedback.
Upgrade for more detailed data and enhanced features

NOAA in the US and Environment Canada HRDPS in British Columbia—on station details and from a map long-press. Save up to 10 weather spots for a quick revisit.
View nearby webcams to see actual ground conditions and verify snowpack observations visually.
Pin up to 3 stations to an Android home widget for depth, temp, and 24h change. Tap a station to open details; refresh without launching the full app.
Compare top favorites on one screen. Pro can send that brief as a daily notification at the time you choose, and flag stations that gained a snowfall amount you set over 8, 12, or 24 hours.
