WeatherAlarm: Storm Radar - Google Play

Weather Alarm tracks rain, thunderstorms, hail, snow and wind around you and tells you when they are heading your way, with an estimated
arrival time.

While other weather apps only show that it is raining somewhere, Weather Alarm checks on live radar whether the precipitation is really
moving toward you. It covers Slovenia, Italy, Croatia and Bosnia and Herzegovina with official national radar data.

HOW IT WORKS

Our servers continuously process live radar data and calculate the direction, speed and strength of every precipitation cell around you.

The key difference: the app does not ring just because there is a storm somewhere nearby. It tells you when a cell is moving toward you and
how many minutes until it arrives. Hiking, cycling or gardening: you will know before the weather changes.

WHAT YOU SEE AT A GLANCE

• What precipitation is falling at your location right now
• How many cells are around you and how strong they are
• The distance to the nearest cell
• An estimate of when rain or hail will reach you

Open the animated radar map with the predicted path of each cell and see where the bad weather is going. There is also a 10-day forecast
for your location and the official warnings of the national weather service for your region.

RADAR WIDGET

The home screen widget shows the radar around you with arrows for where precipitation will move in the next 50 minutes, your location and
the time of the last update. On iPhone you also see it in CarPlay.

CARDS WHEN THE WEATHER TURNS

The home screen shows the turning points: the start and end of a heatwave, a sudden cooling or warming, the first frost and the end of a
long dry spell, with the expected millimetres of rain day by day. After an eventful day, a daily summary waits for you in the evening.

WIND BY ALTITUDE

Wind at the ground and at 1500 and 3000 metres, where the path of a storm is decided. Tap the map to open the vertical profile with the
wind at every altitude and the convective energy of the atmosphere (CAPE).

COMMUNITY

Report hail, lightning, heavy rain, wind or flooding with one tap and follow reports from others live on the map.

Share photos of the sky and storms near you and give a heart to the ones you like. Every month the photo with the most hearts becomes the
photo of the month.

Test your instinct: guess whether a storm or hail will reach a certain city and climb the leaderboard.

EARTHQUAKES AND HOTSPOTS

The map shows earthquakes reported by public seismological services (after the event; the app does not predict earthquakes) and thermal
hotspots from NASA satellites.

Because our servers do the heavy lifting, the app stays light on your battery.

IMPORTANT

Weather Alarm is an unofficial, informational app and is not affiliated with ARSO or any other official service. Notifications are
calculated automatically from radar and satellite measurements and may be inaccurate or delayed. Do not rely on it for safety-critical
decisions. In dangerous weather always follow official warnings and the instructions of the competent authorities.
