About this app

How far away is the lightning? Lightning Log answers from real data: the flashes NOAA's GOES-19 weather satellite saw, measured from your address.

FREE
- The most recent lightning within 25 miles: distance, direction, and how long ago.
- A clear warning when lightning has been within 6 miles in the past 30 minutes.
- When it's quiet near you, how far away the nearest lightning in the lower 48 states is.
- Updates about every minute while the app is open.
- One saved place: type a street address or a ZIP code.

STORM TRACKER (ONE-TIME PURCHASE)
- Is the storm getting closer, holding steady, or moving away?
- Flash counts within 5, 10 and 25 miles, for the past 15 minutes and the past hour.
- The 30/30 clock: minutes since the last lightning within 6 miles, against the National Weather Service guideline of waiting 30 minutes after the last thunder.
- Up to 5 places: home, the ball field, the lake.

GOOD TO KNOW
- The satellite's lightning mapper detects most lightning, cloud flashes included, but not every flash, and positions are good to a few miles. Distances are rounded to whole miles.
- Lower 48 states only.
- For information only, not a safety warning. If you hear thunder, go indoors.

PRIVATE BY DESIGN
No GPS permission, no accounts, no ads. Only rounded coordinates (about 1 km) are sent to look up lightning, and they are not logged or stored.
