UnWX warns you when severe weather is possible. The warnings come from official weather services. Depending on your country, you can receive alerts for thunderstorms, heavy rain, flooding, strong winds, snow, ice, heat and many more.
The map shows warnings for your location and the surrounding area. Each warning explains the weather danger, how serious it is, how likely it is to happen and when it applies. UnWX also includes a weather forecast to help you plan the coming hours and days.
Available for Android and the web. On iOS, you can add the web app to your Home Screen. It then opens and receives notifications like any other app.
Frequently asked questions
Where do UnWX warnings come from?
UnWX uses warnings issued by official national and regional weather services. UnWX brings these warnings together, sends alerts for your monitored locations and shows the warning areas and details on the map.
Does UnWX cover my country?
See the supported country list in the UnWX Google Play description for current coverage, including countries with partial coverage. The available warning types vary by country and issuing service.
What do warning severity and probability mean?
Severity tells you how serious the weather danger is. Probability tells you how likely the event is to happen. They describe different things: an event can be very dangerous even when its probability is low.
What does an UnWX notification look like?
A notification shows the weather danger, affected location, severity, probability and warning period. Tap it to open the warning and read the details.

This example is from the Android app. Notifications look different on other platforms.
Why might I receive a warning without severe weather occurring at my exact location?
Warnings describe risks across an area and a period of time. Conditions can vary within that area, so a warning does not mean that every address will experience the same weather. Read the probability and valid times alongside the severity to understand the warning.
How is UnWX different from Rain Alarm?
UnWX alerts you to official warnings for many types of severe weather, such as storms, heat and floods. Rain Alarm monitors nearby rain and snow using near-real-time radar and satellite data. Use UnWX to follow official severe weather warnings and Rain Alarm to track approaching precipitation.
Does UnWX also include a weather forecast?
Yes. In addition to severe weather warnings, UnWX includes a weather forecast for the coming hours and days. Use the forecast to plan ahead and the warnings to stay informed about potentially dangerous weather.
Can I use UnWX on iOS?
Yes. Open the Web App in Safari and add it to your Home Screen. Open it from there and allow notifications to receive weather alerts.
