Lightning near you, from the same satellite the weather service uses. Florida leads the country in lightning deaths, and almost everyone struck is outdoors — at the beach, on a field, in the backyard — without having heard thunder yet. StormStock now reads NOAA's GOES-East lightning detector every minute and shows you what is happening around you. Turn on "Lightning near me" in Prepare and you get one alert when lightning is detected within about 10 miles of where you last used the app. One — not one per strike. Then nothing until 30 minutes pass with no lightning nearby, which is the National Weather Service's own rule for going back outside. It is off until you turn it on. On the map, a violet layer shows lightning activity from the last 15 minutes, and Home shows a banner when there has been lightning within 10 miles. Detection is by satellite, so it tells you lightning is in that area, not the exact spot it landed. Also in this update: • The assistant and message translation answer again, and keep answering when the service behind them is busy • The storm facts the assistant gives you now come with their source — Ready.gov, FEMA, the NWS When you hear thunder, go inside. No place outside is safe.
