ZoneWatch vs StormNet

Powerful radar, precise forecasts and real-time alerts, now with ThreatNet: ZoneWatch's own severe-weather intelligence. NEW IN 4.0: MEET THREATNET ThreatNet is ZoneWatch's own severe-weather intelligence system, built in-house and found only in ZoneWatch. It scans radar across the country around the clock, finds each storm, follows it scan after scan, and shows you where it's headed next. ThreatNet Storm, the first ThreatNet package: - ZoneWatch Storm Track Intelligence: every tracked storm's outline, speed and direction, updated about every 2 minutes - Where each storm is headed: forecast positions out to 60 minutes, with the path ahead drawn on your map - Strengthening or weakening at a glance, with a trail of where each storm has been - ZoneWatch Lightning Risk and Damaging Wind Risk models, on the map and for your saved locations - Advanced NEXRAD radar: velocity, spectrum width, differential reflectivity and correlation coefficient - Storm-scale radar products: storm total and 1- and 3-hour precipitation, VIL, echo tops and hydrometeor classification - Rotation tracks ThreatNet Storm is included with ZoneWatch Max, or available on its own. ThreatNet works alongside official National Weather Service warnings. ZWCAST Forecasts: - Rapid storm detection for the hours ahead, steadier forecasts for the days after - Expected rain and snow amounts, with lower chances clearly marked - ZoneWatch Flood Notices and Excessive Rainfall Risk levels - Advanced charts for wind, cloud cover and temperature: press and hold to scrub hourly values Radar & Forecast Models: - MRMS and NEXRAD radar, with smoothing on or off - Watches and warnings right on the map - Real-time lightning tracking - Future radar from HRRR, RAP, NAM 3KM, NAM, GFS, ECMWF and ECMWF AIFS, out to 15 days - National Blend of Models (NBM) for temperature, precipitation, wind gusts and more - Snow, wind, visibility, air quality, temperature and more Custom Alerts: - Lightning: by distance, activity level, and quiet-hours bypass - Snow, ice, wind, freezing rain, sleet, extreme temps - Fog, smoke, flooding - Set your own thresholds: only get notified when it matters Track Any Location: - Search by name or drop a pin with exact coordinates - Monitor multiple locations at once - Accurate, up-to-the-minute updates Interactive Map: - Smooth timeline playback - Radar, satellite and forecast layers - Replay past conditions and visualize future forecasts More Data Layers: - Satellite imagery (visible, infrared, water vapor) - Ocean currents, sea temps, wave forecasts - Earthquake tracking and seismic heatmaps ZoneWatch Max: Everything in ZoneWatch, plus ThreatNet Storm. - Advanced severe parameters (CAPE, helicity, shear) - Pressure levels (500mb, 700mb, 850mb, 925mb) - ZW Lightning storm intelligence with predicted paths - Full web radar access - Historical weather reports Already on Pro? You're on ZoneWatch Max now, with nothing to do. ZoneWatch keeps you prepared, wherever you are. Privacy Policy & Terms: https://zonewatchpro.com/tos

StormNet is optimized to provide the most accurate severe weather forecast with NEXRAD, Super-Res Radar. StormNet is completely free, with no ads. Trained on decades of severe weather events, StormNet analyzes high-resolution radar, satellites, ground-based sensors, and weather forecast models in real-time to find complex patterns that lead to severe weather. The model updates every 2 minutes to provide 14-day forecasts for lightning, hail, damaging thunderstorm winds, and tornadoes. Super-Res Radar is the highest-resolution NEXRAD radar data available from 159 stations across the continental United States. Each radar station updates every 3-4 minutes and measures the intensity of precipitation based on how much energy the radar signal receives back from objects in the atmosphere. Combined, StormNet + Super-Res Radar provides a first-of-its-kind, multiple-component severe weather forecast system for the United States. StormNet Map Overlays • Radar: The highest-resolution radar available for the United States from each radar station. • Radar + Risk: NEXRAD radar, alongside StormNet risk probabilities, for the next 4 hours. • Risk Forecast: The StormNet risk probabilities from real-time to 14 days into the future. StormNet Risk Forecasts • Lightning • Hail • Damaging Winds • Tornado Super-Res (NEXRAD) Radar • Radar Reflectivity • Radar Velocity • Spectrum Width National Weather Service Warnings • Tornado • Severe Thunderstorm • Snow Squall • Flash Flood StormNet vs. National Weather Service The National Weather Service, the Storm Prediction Center, and other government agencies are the official sources for watches, warnings, and severe weather information. StormNet should serve as a trusted and automated guide for severe weather risk, but StormNet should not be treated as an official source. StormNet vs. Traditional Weather Models Existing weather forecast models are incredible feats of engineering and predict the ingredients for severe weather, but they are not designed to excel at severe weather forecasting and are not real-time tools. StormNet was trained and optimized to provide severe weather forecasts. StormNet vs. Other Weather Apps Existing weather apps and companies usually pass along official government watches and warnings, and often communicate if lightning or hail is already close by. While these are valuable features, we are not aware of another weather app or company that matches StormNet’s ability to provide real-time updates for lightning, hail, damaging thunderstorm winds, and tornado risk. Powered by OpenSnow In 2011, OpenSnow began predicting snowfall for skiers and snowboarders. OpenSnow has since become a global leader in mountain weather forecasts and expanded to provide forecasts for every type of outdoor activity. Since lightning is a risk to outdoor activities, especially on longer mountain-based adventures, OpenSnow created a weather forecast system that would provide both lightning forecasts to support real-time decisions and multi-day outlooks to support trip planning. Meteorologist Andrew Brady built StormNet to predict the risk of severe weather. OpenSnow acquired his technology in 2024 to help people stay safe and enjoy the outdoors. — Terms & Conditions — StormNet is free and available in the United States.
