July 26, 2026
Storm season, on your radar. Use that with Lightning strikes, real radar, Personal Alerts, and GO! TRACK EVERY NAMED STORM - Live hurricane and tropical storm positions right on the radar map. - The full National Hurricane Center forecast cone, so you can see where it is headed. - Every position carries its own hurricane symbol with its Saffir-Simpson category, and the color deepens from Category 1 through 5, so you can see a storm strengthening at a glance. - Tap any point on a storm's track for category, wind speed, and time at that position. A FASTER, SMOOTHER RADAR - The animation now buffers before it plays, instead of assembling itself while you watch. - Radar paints in seconds on opening the tab, and coming back no longer restarts the load. - Smoother playback with no borrowed frames, and cleaner tiles at deep zoom. - Better battery behavior: the map now goes idle when nothing is moving. REORGANIZED RADAR CONTROLS - Icon-only layer buttons for Rain, Clouds, Lightning, and the new Storms layer. - The bell button now owns alerts; the sliders button owns how the map looks. - Larger, easier to hit controls. Storm and lightning data are satellite and advisory based and approximate. For awareness only: not a substitute for official warnings.
