Powder Radar answers one question: where's the snow? Open the app and instantly see which mountains are getting the most snowfall in the next 72 hours. No clutter, no ads — just forecasts ranked by who's getting dumped on, so you know exactly where to go. Set custom powder alerts on your favorite resorts. Pick a snowfall threshold and how many days in advance you want to know. When a storm is headed for your mountain, you'll get a push notification before it hits — so you can plan your powder day, not just react to one. See the whole picture on the explore map, where live snowfall shows up as a heatmap across entire mountain ranges. Tap any resort to go straight to its forecast. Planning a trip months out? Plan mode ranks resorts by how they actually performed in past seasons — total snowfall, snow days, biggest single day, and which month peaks — so you can pick where and when before you book anything. FEATURES — 7-day snow forecasts for 3,273 ski resorts across 67 countries — Resorts ranked by 72-hour snowfall so the best day is always on top — Interactive explore map with a live snowfall heatmap — Plan mode: historical season data to research trips before you book — Custom powder alerts with adjustable thresholds and lead time — Hour-by-hour breakdown so you know exactly when the snow starts — Home screen widgets showing top snowfall at a glance — Summit and base elevation forecasts — snow line matters — Season stats per resort: totals, snow days, best day, % of normal — Published forecast accuracy, so you can see how we actually score — Dark, glanceable design built for quick checks on the lift Most forecast apps never tell you whether they were right. We publish how our forecasts scored against measured snowfall, by lead time and by resort. Check it before you trust it. Built by a snowboarder who got tired of checking five different weather apps before every trip.
