In Spain, AEMET issues METEOALERTA warnings at three levels: yellow (no risk to the general public but to outdoor activities), orange (significant risk, disruption to daily life), and red (extreme risk to the population). They cover phenomena like heavy rain, wind, snow, heat waves, and swell.
European system
The Meteoalarm system coordinates warnings from 36 European weather services with common symbology. Red warnings activate civil protection plans and may involve school closures, road closures, and activity suspensions. Average warning lead time ranges from 12 to 72 hours depending on the phenomenon.
