ThunderTracker: Lightning Map

See recent reported lightning around you—or explore another city—with ThunderTracker. ThunderTracker puts recent lightning activity on a clear, interactive map. Use your location or search for a city, choose the area you want to view, and inspect reported strikes from the last five minutes. FEATURES • View recent reported lightning on an interactive map • Search cities and save places for quick access • Adjust the map search radius from 5 to 100 kilometers • See the nearest strike’s distance, direction, and age • Review strike type, coordinates, peak current, and polarity when available • Center an individual strike on the map or share its location • Enable nearby lightning alerts around your device with a 5–50 kilometer radius • Follow your location in the background when permission is granted • Use a 30-minute wait timer that restarts after a new nearby strike • Report thunder yourself to restart the timer • Show the wait timer on your Lock Screen on supported iPhones • Switch between kilometers and miles CLEAR ABOUT THE DATA Newer strike markers appear brighter while older reports fade. Data age and service status remain visible, so you can tell when information is fresh, delayed, or unavailable. IMPORTANT ThunderTracker is a supplemental weather-awareness tool. Lightning data, alerts, and notifications may be delayed, incomplete, or unavailable. A map with no reported strikes—and a timer reaching zero—does not mean conditions are safe or provide an official all-clear. Always follow official weather alerts, local guidance, and your own judgment. Lightning data is provided by Vaisala Xweather.
