Catalonia, Aragon and the Balearic Islands face orange-level weather alerts. Intense rain, hail and strong winds are expected. Authorities warn of local flooding and dangerous sea conditions.
Weather authorities have issued an orange alert for Catalonia and Aragon this Monday, as both regions brace for intense rainfall and severe storms. The alert, which also affects the Balearic Islands, signals a significant risk of flooding, hail and damaging winds, with the most critical period expected from midday through the evening.
In Catalonia, the orange warning will be in force from 12:00 and remain active until the end of the day. The heaviest downpours are forecast for the Valle de Arán and parts of Lleida and Barcelona provinces, where rainfall could reach up to 30 litres per square metre in just one hour. Meteorologists warn that storms may bring large hailstones, potentially exceeding five centimetres in diameter, and very strong wind gusts, especially in Lleida.
Aragon faces similar risks, with the orange alert covering the entire day. The province of Huesca is particularly exposed to heavy rain and hail, with precipitation rates matching those expected in Catalonia. Strong winds are also anticipated, increasing the likelihood of localised damage and travel disruption.
Meanwhile, the Balearic Islands are under orange alert along the Menorca coastline, where authorities have highlighted the risk of 'rissaga'—a sudden oscillation in sea level that could reach up to 1.2 metres. This phenomenon poses a threat to boats and coastal infrastructure throughout the day.
Seven other autonomous communities—Andalusia, Cantabria, Castilla y León, Castilla-La Mancha, Extremadura, Galicia and Navarra—are on yellow alert for rain and storms, indicating a lower but still notable risk of adverse weather. The widespread warnings reflect a pattern of unstable conditions across much of Spain, with authorities urging residents to remain vigilant and follow official guidance.
Recent weeks have seen a series of severe weather events in Spain, with similar alerts issued earlier this summer. For context, a previous Atlantic storm in August brought heavy rainfall and triggered widespread warnings in Catalonia and the Balearic Islands, highlighting the ongoing vulnerability of these regions to sudden meteorological shifts.
Spain's alert system uses a colour-coded scale to indicate risk, with orange representing a significant threat to safety and property. Such warnings typically prompt local authorities to prepare emergency services, monitor river levels and advise the public to avoid unnecessary travel. The combination of intense rainfall, hail and wind can lead to flash flooding, fallen trees and hazardous driving conditions, particularly in mountainous and coastal areas. The phenomenon of 'rissaga' is unique to certain Mediterranean locations and can cause rapid changes in sea level, occasionally resulting in damage to harbours and moored vessels. As climate patterns shift, episodes of extreme weather have become more frequent in Spain, making timely alerts and public awareness increasingly important for minimising impact.
