Spain's Mediterranean coast is under orange weather alerts as a strong storm front brings flash-flood risks, large hail and damaging winds. The Agencia Estatal de Meteorología (Aemet) has identified the highest risk in Catalonia, the Balearic Islands, Comunidad Valenciana, Murcia and Almería. Aemet bulletins for September 9, 2026, put all the Balearic Islands, Catalonia, Murcia and the Valencian Community under orange-level warnings for rain and thunderstorms. Local authorities are preparing for possible disruption and damage.
Residents in these regions woke to warnings of sharp temperature drops and localized flooding. A sharp cold front is driving the storm, which is expected to bring heavy downpours and hailstones large enough to damage cars and property. Strong winds could bring down trees and power lines. The most dangerous conditions are expected in the southeast and the Balearic Islands, especially overnight and into Thursday morning. On the northern coast of Alicante, rainfall could reach 60 liters per square meter in 12 hours and 40 liters per square meter in just one hour, with a risk of large hail and strong winds.
On the Balearic Islands, wind gusts are forecast to reach 90 km/h, and orange alerts for heavy rain and thunderstorms now cover the entire archipelago.
AEMET
Aemet spokesperson Rubén del Campo said the orange alerts are staggered: Catalonia remains under warning until 13:59, the Balearic Islands from midday, Comunidad Valenciana and Murcia from 14:00, and Almería from 16:00. Del Campo urged the public to follow Protección Civil advice and avoid unnecessary travel during the worst of the storms. In Catalonia, Protección Civil has already sent ES-ALERT messages restricting movement and activities in several comarcas, including Alt Penedès, Baix Penedès, Garraf, Baix Llobregat and Vallès Occidental. It has also suspended some urgent social and medical services.
Seven autonomous communities are under some form of weather alert. Andalucía faces orange warnings for storms and a yellow warning for heat, while Aragón is under a yellow wind alert. The Balearic Islands, Catalonia, Murcia and Comunidad Valenciana face orange-level threats from rain and storms, alongside additional yellow warnings for wind and rough seas. In Murcia, maximum temperatures could still reach 37°C despite the storm risk. RTVE and local weather reports say the front is bringing a sharp temperature drop of about 8-12°C across eastern Spain and the Balearics, while the southeast remains unusually hot.
As the front passes, temperatures are expected to fall by 8 to 12 degrees across much of eastern Spain and the Balearics. In the far southeast, the heat will linger. Northern winds will pick up in the northeast and over the islands, adding to the risk of dangerous conditions.
Alongside orange alerts, Andalucía and Aragón have yellow warnings for wind, coastal phenomena and heat. At least 7-8 autonomous communities are affected by this unstable weather episode.
Official weather bulletins
Overnight into Thursday, violent storms and strong winds will continue in the southeast, Melilla and the Balearic Islands, with conditions expected to ease by midday. Galicia and the Cantabrian coast will see only light rain, while the rest of the country will have clearer skies. The coldest night will be inland, with temperatures dropping below 10°C in many northern areas.
By Friday and into the weekend, stable, high-pressure weather is expected to return. Temperatures will rise above 30°C in many regions and could reach 38°C in some valleys. In the Canary Islands, temperatures will return to normal midweek after a period of intense heat, then climb again over the weekend, alongside strong trade winds and occasional light rain in the north.
Spain’s Mediterranean coast has faced repeated weather extremes in recent years, from wildfires to sudden storms. As reported earlier, Valencia is still recovering from a major wildfire, a reminder of how quickly the region can shift between drought and flooding.
These latest alerts show the challenge for emergency services and local governments, which must prepare for heat and flooding in the same week. Abrupt weather swings are becoming more common in Spain, forcing authorities and residents to adapt quickly. The current episode shows the risks violent storms pose to daily life and infrastructure in Mediterranean Spain.
