Zyntria Winter Adventure

Zyntria® Winter Adventure is built for winter—and designed for year-round outdoor planning. Built by a U.S. Navy veteran with experience supporting Marine Corps units and a background in data analytics and decision-making, Zyntria turns complex outdoor information into practical planning guidance. Use Zyntria for skiing, snowboarding, cross-country skiing, snowshoeing, winter hiking, year-round hiking, mountain trips, stargazing, and more. READINESS & DECISION INTELLIGENCE See GO / CAUTION / NO-GO guidance based on the conditions that matter for your activity. Zyntria separates Activity Feasibility, Experience Quality, Data Confidence, and predictive context. Choose Recommended, Conservative, or Custom Intelligence. PLAN MY ADVENTURE Choose activity, destination, start time, duration, environment, and profile. Use Zyntria® Time Shift, Find My Best Window, and Compare Times to evaluate the full activity window and identify stronger times to go. MULTI-SOURCE WEATHER & WINTER INTELLIGENCE Go beyond a single forecast. Zyntria combines public weather, snow, terrain, avalanche, environmental, access, data to build a broader picture of changing conditions. Sources can include the National Weather Service, NOAA NBM, HRRR, RTMA, MRMS Radar, NOAA Snow Analysis, SNODAS, NRCS SNOTEL/AWDB, USGS 3DEP terrain, Avalanche.org, NWS avalanche guidance, regional avalanche centers, NOAA National Water Model, EPA AirNow, State 511, and resort/trail condition sources. Where supported, Zyntria evaluates forecast confidence, model agreement, storm timing, snowpack trends, whiteout potential, freeze/thaw, rain-on-snow, wind loading, air quality, access, and terrain. MAP, ROUTING & ROUTE INTELLIGENCE Search resorts, trailheads, mountains, trails, and destinations. Explore locally, save waypoints, build Winter Routes from nearby access points, or use Full Trip for drive, access, route, and return. Build supported routes across hiking trails, Nordic routes, ski-tour routes, pistes, lifts, and access paths. Route Intelligence evaluates terrain, weather, readiness, confidence, hazards, avalanche context, and limiting segments. SAVED TRIPS, ALERTS & ADVENTURE LOG Save timing, profile, readiness, mapped journey, and Route Intelligence together. Reopen trips and monitor changes. NIGHT SKY INTELLIGENCE Plan after dark with darkness windows, moon phase, illumination, visibility, cloud cover, and Night Sky quality. SAFETY & RESCUE Access position sharing, emergency-reference guides, official hazards, avalanche information, and a user-directed 911 handoff. Premium Rescue Assist can organize responder-ready incident details. FREE & PREMIUM Core weather, forecasts, radar, readiness, official hazards, avalanche information, position sharing, 911 access, and emergency-reference tools remain available without Premium. Premium adds Custom Intelligence, Time Shift, Best Window, Compare Times, advanced Night Sky tools, Adventure Map, waypoints, Winter routing, Route Intelligence, Full Trip, offline route data, Saved Trips, alerts, Adventure Log, and Advanced Rescue Assist. IMPORTANT SAFETY INFORMATION Zyntria® Winter Adventure is a planning and situational-awareness aid. It is not a certified navigation system, avalanche forecast center, emergency-response service, or substitute for official warnings, avalanche forecasts, maps, ski patrol, search and rescue, 911, equipment, training, local knowledge, or judgment. GPS, cellular service, weather, radar, avalanche information, and emergency services may be delayed, incomplete, inaccurate, or unavailable. Missing data must never be interpreted as safe. Official warnings, avalanche-center information, closures, authorities, and real-world conditions always take priority.
