The Spanish meteorological agency Aemet has raised weather warnings to orange for the province of A Coruña and central Lugo, citing the risk of exceptionally heavy storms this weekend. Forecasts indicate rainfall could reach 30 liters per square meter, equivalent to 30 millimeters, in one hour, particularly between 16:00 and 23:59. The alert comes as a cold upper-level depression, known as a dana, settles off Galicia’s western coast, creating a sharp contrast in weather patterns across Spain.
While much of the peninsula braces for a surge of subtropical heat driven by southerly winds from North Africa, Galicia faces the opposite scenario. Here, cold air at high altitudes meets Atlantic humidity as daytime temperatures rise, fueling rapid cloud development and intense convective storms. Aemet says these conditions are especially favorable for organized thunderstorms to form along the coast and move inland, a pattern less typical for the region.
The most acute risk is centered on A Coruña, where oceanic moisture and cold upper air, combined with surface warmth, are expected to trigger severe downpours, hail and frequent lightning. Central Lugo is also under orange alert, while the rest of Galicia remains at yellow level, with rainfall of up to 15 liters per square meter, or 15 millimeters, in an hour expected. The agency warns that the volume and intensity of precipitation could lead to localized flooding and hazardous conditions, particularly in urban and low-lying areas.
The warnings fall under Aemet’s national Meteoalerta structure, which provides updated information on hazardous weather for up to 72 hours and as events develop. Its alert levels reflect the expected severity and potential impacts of hazards including heavy rain and storms, as well as wind and coastal conditions. On Sunday, the unstable atmosphere is set to persist, with alternating clouds and clear spells. Afternoon storm clouds are likely to redevelop, especially in Lugo, though no further alerts have been issued for now. A impressive drop in temperatures is forecast, bringing relief from the recent persistent heat in Galicia’s interior. Unsettled weather is expected to continue into the following week, with Aemet’s outlook pointing to wetter-than-average conditions for Galicia. Temperatures should remain above normal in the north but are predicted to be average in the south of the region.
This episode shows how unpredictable Spain’s weather can be, with rapid shifts between heatwaves and storms affecting communities in different ways. Recent studies have also drawn attention to how such extremes affect daily life, including regional disparities in heat protection. For example, a recent report on Barcelona revealed impressive inequalities in access to air conditioning during heatwaves, pointing to the broader challenges posed by climate volatility.
Galicia’s current situation reflects the region’s vulnerability to sudden weather changes. Atlantic influences and upper-level atmospheric disturbances can bring abrupt shifts from dry spells to intense rainfall. Local authorities advise residents to follow Aemet updates and take precautions during periods of heavy rain, especially in areas prone to flooding. As climate patterns continue to fluctuate, the ability to respond quickly to weather alerts is increasingly critical for communities across Spain.
