Severe storms are expected across eastern Spain as the current heatwave intensifies. From Friday through Saturday, meteorological models predict storm clouds will rapidly develop across the Pyrenees, Aragon and Catalonia, as well as Teruel, Navarra and parts of the Mediterranean coast. The storms are expected to bring intense downpours and strong wind gusts, with hail also possible, disrupting the stable weather that has dominated much of the country in recent days. Spain’s national meteorological agency, AEMET, uses its Meteoalerta system to issue warnings for adverse weather up to 72 hours ahead, covering heavy rain and thunderstorms, as well as hail and strong winds.
Temperatures have already topped 40°C in several provincial capitals, with the most impressive anomalies recorded in the northern interior. The fourth heatwave of the summer is pushing temperatures to extreme levels, and forecasts indicate conditions could worsen over the weekend, especially in Mediterranean communities and the Canary Islands. High temperatures combined with incoming storm systems are creating a volatile atmosphere and raising the risk of sudden weather changes.
European weather models forecast that storm activity will intensify from midday, particularly in mountainous areas. The Pyrenees, northern Catalonia, Teruel and Navarra are expected to see the most severe impacts, including locally heavy showers and possible hailstones exceeding 2 cm in diameter. Wind gusts in these regions could surpass 50 to 60 km/h, raising concerns about property damage and public safety. Lesser but still impressive showers are forecast for the interior of Castellón, Albacete, the northwest of Murcia and the eastern Andalusian sierras. Northern Galicia and the Cantabrian slope may also see isolated storms and showers.
Storm cells in the Pyrenees and Teruel could become more organized, producing rainfall accumulations above 20 l/m² in some locations. AEMET’s observation service publishes hourly readings and daily extremes, as well as precipitation accumulations from its station network, including stations in Girona and the Pyrenean area. Saharan dust will further complicate conditions, especially in the south and the Balearic Islands, where skies will look hazy and muddy rain may fall in some places. Along with smoke from ongoing wildfires, the dust is expected to reduce air quality and visibility. The risk of new fires remains high or extreme across much of Spain, as dry vegetation and lightning strikes from storms create hazardous conditions. Recent events, including mass evacuations in Ávila over wildfire threats, show the dangers of this combination of heat and unstable weather, as detailed in reports on emergency evacuations in Ávila.
On Saturday, storm activity is expected to return to many of the same areas. Cumulonimbus clouds will develop again from midday, with afternoon showers likely in Teruel, inland Castellón, eastern Castilla-La Mancha, southern Valencia, the eastern Andalusian sierras and the Pyrenees. Rainfall totals, but, are expected to be lower than on Friday. Isolated hail and strong winds remain possible, and muddy rain may persist in the southeast because of lingering Saharan dust. Northern Galicia and the Cantabrian region will continue to see occasional showers and storms, while scattered storm cells may reach the Pyrenean range on Sunday, possibly extending to the eastern interior.
Spain’s summer weather is increasingly shaped by the interplay of heatwaves and sudden storms. The current pattern brings extreme temperatures and Saharan dust alongside unstable atmospheric conditions, posing challenges for residents and emergency services. Wildfire risk remains a serious concern, especially as lightning and strong winds can quickly escalate local incidents. Spain has experienced a impressive rise in extreme weather events in recent years, with the Mediterranean and northern regions particularly vulnerable to rapid shifts between heat and storms. Authorities continue to monitor the situation closely and urge residents to watch for weather warnings and take precautions against heat and severe storms.
