MesoSky Lightning showing a real-time strength heatmap of lightning over the Gulf Coast

01 / Live

Straight from orbit

See it the second
it happens.

Cloud-to-ground and in-cloud flashes from the GOES-18 & GOES-19 satellites, painted on the map moments after they strike — colored by strength, so one glance separates a distant flicker from a violent close hit.

  • A living heatmap that heats up where the storm hits hardest
  • Tap any strike for strength, energy, footprint & distance
  • Full-resolution NEXRAD Level 2 radar underneath
Tapping a strike reveals a strength gauge, energy, footprint and distance

On your terms

Know before it's
overhead.

Get a push the moment lightning enters your bubble — even with the app closed. You set the rules: how often you're notified, and for how long. No spam, no nagging.

  • Alert at most every 5, 15, or 30 minutes
  • Keep alerting for the next hour, 6, 12, or indefinitely
  • A radius you choose, around you or any pinned spot
Lightning alert controls: notify cadence and duration

how you like it.

  • Intensity heatmap, footprint coverage, or risk-area overlays
  • dBZ filter, opacity & smoothing for the radar
  • Strength emphasis, flash animation, retention & more
