After a brief respite, Spain is bracing for a significant shift in weather patterns. According to Rubén del Campo, spokesperson for the Agencia Estatal de Meteorología (Aemet), the nation is facing «several unsettled days due to the influence of Atlantic storms». This meteorological shift is being driven by two distinct low-pressure systems: an unnamed storm already bringing rains to parts of the country, and Storm Nuria, which Aemet officially named on Tuesday as the fourteenth high-impact storm of the season (Torres Benayas, 2025).

The Unnamed Storm: A Wet Start

The initial impact is already being felt across Spain. The unnamed storm, which began its course by delivering initial rains to Andalusia on Tuesday, is now extending its reach across the country. As reported by *El País* (2025), this weather system is combining with humid air from the Mediterranean, creating conditions ripe for widespread showers and thunderstorms, particularly across the northern half of the peninsula. The southeast is expected to be spared from the initial downpour. The Canary Islands are also anticipating rainfall, with western islands, especially Tenerife, potentially experiencing heavy precipitation (Torres Benayas, 2025).

Temperature Drops and Weather Alerts

Accompanying these storms is a noticeable drop in temperatures across much of Spain. The Agencia Estatal de Meteorología (Aemet) forecasts a significant cooling, especially in the north and east, where temperatures could plummet by 8° to 10° Celsius compared to Tuesday's values. This sharp change marks a stark contrast to the recent spell of spring-like weather. In response to these conditions, Aemet has issued yellow alerts – the lowest level on a three-tier scale – for rain, thunderstorms, wind, and rough seas in seven regions: Aragon, Asturias, Castile and León, Galicia, Navarra, the Basque Country, and La Rioja (Torres Benayas, 2025).

Storm Nuria: Intensifying the Impact

The situation is expected to escalate on Thursday with the arrival of Storm Nuria. The Agencia Estatal de Meteorología (Aemet) reports that Nuria will bring very strong winds and rough seas to the Canary Islands, along with intense rainfall, particularly on the mountainous islands. The storm's effects will then extend to the Iberian Peninsula, bringing significant rainfall, especially to the interior. Galicia and the Mediterranean area are expected to receive less rainfall, but strong winds are still anticipated in the northern third of the peninsula (Torres Benayas, 2025).

Temperature Variations and Snowfall

While temperatures are expected to decrease in the interior of the peninsula, the Cantabrian and Mediterranean regions are likely to experience a rise. Murcia and other southeastern locations could see temperatures exceeding 25°C. Snowfall is anticipated at altitudes above 1,500 meters. The Canary Islands are under an orange alert, the second-highest level, due to wind, while Aragon, Navarra, and the Basque Country are under yellow alerts (Torres Benayas, 2025).

Looking Ahead: Friday and Beyond

As the week progresses, the snow level is forecast to rise to between 1,800 and 2,000 meters on Friday due to rising temperatures. According to the Agencia Estatal de Meteorología (Aemet), Storm Nuria will continue to generate strong winds in the northern third of the peninsula, along with widespread and potentially stormy rainfall, less likely along the Cantabrian coast and the Mediterranean area (Torres Benayas, 2025). Heavy rainfall is expected in western Andalusia, Extremadura, and particularly around the Sistema Central, including southern Castile and León, northern Extremadura, and the Sierra de Guadarrama. The Canary Islands are expected to see a reduction in rainfall.

Weekend Outlook

The unsettled weather is predicted to gradually subside on Saturday, although early morning rainfall is still expected, especially in the northern third of the peninsula and in mountainous areas. These conditions are likely to persist longer in the Pyrenees and the Sistema Central. A new front is anticipated to bring rain to the western Canary Islands. Temperatures are generally expected to drop, except in the Mediterranean, where they will rise, with temperatures in Alicante and Murcia potentially exceeding 25°C (Torres Benayas, 2025).

Long-Term Uncertainty

Beyond the weekend, forecasting becomes less certain. However, the Agencia Estatal de Meteorología (Aemet) suggests that rainfall could return to southeastern areas of the peninsula, and temperatures may begin to rise in the following days (Torres Benayas, 2025).

March Rainfall: A Historical Perspective

Reflecting on the recent past, March proved to be exceptionally wet. The Agencia Estatal de Meteorología (Aemet) confirms that March was the third wettest in the historical series dating back to 1961, with a national average of 149 liters per square meter (Torres Benayas, 2025). Only March 2013 and 2018 recorded higher rainfall, with 160 and 164 liters respectively. This year’s total is two and a half times the normal average. Notably, rainfall in the central and southern peninsula, as well as the interior Mediterranean area, was more than three times the normal amount. In contrast, Galicia and other parts of the Cantabrian region experienced a drier than usual March (Torres Benayas, 2025).
