Spain’s national weather agency AEMET has issued a warning of heavy storms across the Mediterranean region and the Balearic Islands early this week, with the potential to cause flooding and disruption.
Between Monday and Wednesday, a trough of cold Atlantic air will combine with humid coastal winds from the Mediterranean, creating unstable conditions. The agency expects torrential downpours in Catalonia, the Valencian Community and the Balearics, with Murcia also affected to a lesser extent.
Rainfall could reach 60–80 litres per square metre in just 12 hours, accompanied by hail and violent gusts of wind. The situation is set to peak on Tuesday in the Balearics, where accumulations of up to 140 litres per square metre are possible within half a day.
By Wednesday, the intensity is expected to ease, though showers and thunderstorms will persist in Catalonia and the islands, particularly during the central hours of the day. Conditions should gradually improve from Wednesday afternoon onwards.
AEMET has stressed that small shifts in the trough’s position could significantly alter where the heaviest storms strike. Residents are therefore urged to remain alert to updated forecasts and advisories.
Local authorities have warned of the risk of flash flooding in urban areas and possible travel disruption. Ferry crossings and flights to the Balearics may also be affected if conditions worsen as forecast.
