What to know

What does a warning tell me?

A warning communicates an official assessment for a place and time window. Open it for the full description, issuing authority and instructions. Severity is only one part of the message; certainty, urgency and local context also matter.

Is this a complete worldwide warning service?

No. Forecasts are available globally, while official warning coverage depends on connected national sources. Check the coverage note and browse your country. Missing coverage does not mean no dangerous weather.

What should I do when my area is affected?

Read the official instructions and act on advice from local emergency services. Do not wait for this site to confirm a warning received through an official channel.
