Customize weather your way! Radar, Lightning, Beach, Marine, and real conditions!
Add your own weather ratings based on YOUR thresholds.
See every lightning strike live on a beautiful radar map, and get warned before the storm reaches you.
LIGHTNING, LIVE ON THE MAP
- Satellite-detected lightning strikes appear right on the radar, color-coded by age (bright red for the newest, yellow as they get older), with distance rings around you and a readout that always shows the nearest strike ("within ~10 mi"). Pro members get proximity push alerts with quiet hours, delivered even when the app is closed, so your phone warns you before you hear thunder. Set your alert distance anywhere from 1 to 30 miles with a simple slider. Free users can tap the lightning layer for a short live preview of real strikes.
Lightning detection comes from the NOAA GOES satellite network covering the Americas. Distances are approximate. For awareness only: not a substitute for official warnings.
RADAR THAT LOOKS THE PART
A high-contrast storm map built for one job: showing you the weather.
- High-resolution US NEXRAD radar as smooth, vivid color at every zoom
- Satellite precipitation worldwide
- Satellite clouds, day and night, across the globe
TRACK EVERY NAMED STORM
- When a hurricane or tropical storm is active, it appears right on your radar. See where it is now, where it has been, and where the National Hurricane Center expects it to go, with the full forecast cone drawn on the map.
THE RATING THAT KNOWS YOUR LIMITS
- HarborCast turns NOAA data into one clear answer: Good, Poor, or Dangerous, hour by hour. Set your own wind, gust, wave, and visibility thresholds and the rating adapts to you. Search any city or coast, or save your current GPS location with one tap.
