About this extension
Lightning Tracker delivers real-time lightning strike proximity alerts, severe thunderstorm tracking, and live weather radar directly in your browser.
Powered by optical telemetry downlinked directly from NOAA GOES-18, NOAA GOES-19, and EUMETSAT MTG geostationary weather satellites, Lightning Tracker calculates the exact geodesic distance to nearby electrical discharges so you know immediately when severe weather approaches your area.
Key Features:
100% In-Browser Privacy:
Your privacy is protected. Geolocation coordinates are processed strictly inside your local browser sandbox to compute distances. Coordinates are never transmitted over the network, never stored on external servers, and never logged.
