Where the data comes from
Every warning on Waarning comes from a public source. We show the source with each item, so you can always check it yourself.

How severity is shown
Waarning keeps the provider's own severity labels rather than inventing a score. A colour and a word make it quick to scan, but the source text stays visible.
Low
Worth knowing
Minor or advisory information. Usually no immediate action needed.
Moderate
Be aware
Conditions could affect you. Check the details and plan ahead.
Severe
Take action
Follow the instructions from the source. Stay informed and follow official guidance.
What Waarning is not
- Not a prediction. Waarning reports current conditions and official warnings. It does not forecast earthquakes, crime or scams.
- Not a replacement for official guidance. In an emergency, follow your local authorities.
- Not infallible. Sources can be delayed, incomplete or regional. Street-level crime data is UK-only, for example.
- Not storing your location. Your precise location is never saved. Coarse location is only kept if you choose it, and only in your own browser.
