SEE NEARBY LIGHTNING

Stormivo

A clearer view of nearby lightning, with distance alerts you control.

Stormivo is an Android app in development. Set two alert distances, starting at 10 and 30 miles. Choose when map markers turn yellow and disappear. Tap an observation for its date and time.

Know what the map means

NOAA satellites observe lightning in clouds and toward the ground. Markers show approximate flash centers; they do not identify exact ground impacts. Coverage and detection quality vary, and regional validation is ongoing. The app is not yet available on Google Play.

Alerts are experimental

Location, internet access, Android settings, source delays and push delivery affect alerts. Missing markers or notifications do not mean conditions are safe. Do not wait for an app alert to seek shelter when thunder is heard.
