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.
