WeatherAlarm: Storm Radar

Weather Alarm tells you when rain, a thunderstorm or hail is actually heading your way, and how many minutes until it arrives. Other weather apps show that it is raining somewhere. Weather Alarm tracks every storm cell on live radar, calculates its direction and speed, and notifies you only when a cell is moving toward you. Hiking, biking, grilling or driving home: you know before the weather changes. NOW COVERING THE UNITED STATES Weather Alarm covers the contiguous United States with NOAA MRMS radar, updated every few minutes, along with Slovenia, Italy, Croatia, Bosnia and Herzegovina, Austria and Germany. Temperatures in °F and distances in miles. WHAT YOU SEE AT A GLANCE • What is falling at your location right now • The nearest storm cell, its distance and strength • Estimated arrival time of rain and hail • The predicted path of every cell on an animated radar map • Lightning from NOAA GOES satellites • National Weather Service alerts and text forecast for your location • A 10 day forecast NOTIFICATIONS THAT MEAN SOMETHING No alarm just because there is a storm 50 miles away. You get a notification when a cell is on track to reach you, with the expected arrival time. You choose the location: follow you by GPS, or set a fixed place such as your home. WIDGET AND CARPLAY The home screen widget shows the radar around you, where precipitation will move in the next 50 minutes and your position. On iPhone you also see it in CarPlay. CARDS WHEN THE WEATHER TURNS The home screen highlights the turning points: the start and end of a heat wave, a sudden cooling, the first frost and the end of a long dry spell. WIND AND STORM ENERGY Wind at the ground and higher up, where the path of a storm is decided, plus the convective energy of the atmosphere (CAPE), from NOAA models. COMMUNITY Report hail, lightning, heavy rain, wind or flooding with one tap and see reports from others live on the map. Share photos of the sky and storms near you. Guess whether rain or a storm will reach a city and climb the leaderboard. Our servers do the heavy lifting, so the app stays light on your battery.
