About Weather Bolt
Weather Bolt (formerly HarborCast) shows radar, lightning and the forecast for the places you save, with tides and marine tools you can turn on if you are out on the water. RADAR A radar map that plays back the last 2 hours. Pan, zoom and scrub back through time to see where rain is heading. Radar is free. LIVE LIGHTNING See lightning strikes on the map as they happen, with the distance to the nearest one. A short free preview is included. Live lightning is part of Pro. ALERTS AND STORMS Pro sends a notification when lightning is close, or when a tropical storm's forecast path comes within the distance you pick, even when the app is closed. Pro also adds storm tracks, cones and forecast points. FORECAST Current conditions, the next hours and a daily forecast. Free shows today and the next 3 days. Pro shows all 7 days. YOUR OWN LIMITS Set your own numbers for wind, gusts, rain and visibility (and waves with Tides & marine on). The app rates each hour Good, Caution or Danger against them. Saving your limits is part of Pro. WIDGETS AND APPLE WATCH Home Screen widgets and Watch complications show current conditions. TIDES AND MARINE Optional. Turn on tides and the marine forecast if you spend time on the water. DATA Weather data comes from NOAA, the National Weather Service and NASA imagery. Weather Bolt is not endorsed by NOAA. Pricing and any free trial are shown in the app and on the App Store before you subscribe.
What’s new

Weather Bolt is the new name for HarborCast. -Storm alerts now look ahead. Pick a distance up to 1,000 miles and get an alert when a tropical storm's 5-day forecast path comes within it. The alert shows the storm's strength, how far away it is, which direction, and when it passes closest. -Storm alerts can now check in the background, so a storm in the Gulf or Atlantic can reach you before you open the app. -Tides and marine data are now optional. Turn them on in Settings if you boat, fish or paddle. -The hurricane track now draws the full line up to the storm. - New app icon.
