See thunderstorms the moment they happen.

In Settings, touch and hold the map (or use your location) to set the center of the alert area. The red circle shows the area in which a push notification is sent when lightning is detected. Adjust the size with the slider.

Notifications must be allowed for BlitzortungLive in the iOS Settings.

New strikes appear as pulsing dots. They shrink, fade and change from yellow to red within about one minute. The lightningmaps.org layer shows strikes of the recent past, colored by age.

“Live” means strikes are being received. During interruptions the app reconnects automatically.

Use ▶ to animate, or drag the timeline. The chip at the top always shows the displayed time. Forecast images are marked in purple with a dashed outline – they are predictions, not measurements.

When you look at a past radar image, the map shows the strikes the app received around that time. Strikes are only recorded while the app is open.

Both are only available for Germany and only show something when there are thunderstorms there. The legend tells you when there is currently no lightning or no active storm cell in Germany.

Pink areas show where DWD currently detects thunderstorms (solid outline) and where it expects them during the next hours (dashed outline). The Lifted Index shows how unstable the air is according to a weather model: the more negative, the higher the potential for thunderstorms. Stable areas remain transparent.

No. There are no ads, no analytics and no tracking. Your location is only used when you ask for it (center the map, set the alert area). Details are in the privacy policy (German).
