iPhone

Live snow, pass, and avalanche conditions for the Seattle mountains — one screen, every number stamped when it was fetched, verbatim from the people who measure them. It’s 5 AM and it snowed somewhere. Which mountain today — and do I need to leave now? PowDay answers that, every storm morning, for Crystal Mountain, Stevens Pass, The Summit at Snoqualmie, and Mt. Baker. ONE SCREEN, TEN SECONDS One card per mountain: real snow depth and overnight accumulation from USDA SNOTEL stations on the mountain, NWS forecast snowfall, WSDOT pass conditions with chain requirements word for word, and NWAC’s avalanche danger rating — verbatim, always linked to the full forecast at nwac.us. EVERY NUMBER SAYS WHEN IT WAS FETCHED Data carries its timestamp and flags itself stale past 90 minutes. If a source goes down, you get a link to the official page — never a silent guess. Works on mountain cell: the last good numbers are cached on your phone. YOUR MOUNTAINS, YOUR ORDER Rank the mountains the way you’d check them on a snowy morning. Free shows your first two, forever. STORM ALERTS, FREE Pick a snow threshold and an hour. When tomorrow’s NWS forecast for one of your mountains crosses it, your phone tells you — computed on the device itself, so no server is watching your mountains. POWDAY PRO — ONE PURCHASE, NO SUBSCRIPTION A single unlock adds every mountain and share cards for the group chat. WHAT POWDAY DOESN’T DO No accounts. No tracking. No ads. And no forecasting commentary of our own — we relay what NWS, SNOTEL, WSDOT, and NWAC publish, exactly as they publish it. Conditions change fast in the mountains; always check nwac.us and wsdot.wa.gov before you go. Not affiliated with any resort. Directions open in Apple Maps.
