A new rainstorm has begun in the Peninsula and the Balearic Islands, caused once again by a dana, with effects expected to last until at least Saturday. The State Meteorological Agency (Aemet) predicts that on the first day, the heaviest rainfall will be in the Balearic Islands, while on Wednesday the most affected areas will be Catalonia, Valencia, and Andalusia. On Thursday, there is a lot of uncertainty, but Aemet initially points to western Andalusia, the area between the Ebro Delta and Nao Cape, as well as the central area. Throughout this new storm, Aemet expects very strong and persistent rainfall in the Balearic Islands and the Peninsular Mediterranean area, as well as abundant rainfall in parts of the Cantabrian region and the central zone.
The intensity and persistence of this new storm remain uncertain, but Aemet warns that the southern regions of Catalonia, Castellón, and southern Valencia are particularly vulnerable due to previous damage from the previous dana. Rainfall of up to 100 liters per square meter is expected in these regions from Thursday to Saturday. Aemet cannot yet specify which specific areas within the affected zone will receive the heaviest precipitation but hopes to provide more detailed forecasts throughout Tuesday. On the first day of the storm, the focus is on the Balearic Islands, where very heavy and potentially torrential rain is expected, with accumulations of over 100 liters in 12 hours. Several regions including Aragon, Asturias, and Catalonia have been placed under warning for rain, storms, snow, wind, or rough seas.
Wednesday is expected to be the worst day of the storm, with rainfall expected across much of Spain, particularly in northern Catalonia, southern Tarragona, Castellón, southern Valencia, northern Alicante, the coasts of Málaga and Granada, and in the Balearic Islands. Andalusia, the Balearic Islands, Catalonia, and Valencia have been issued with an orange warning for rain, while other regions, such as Castilla y León and Galicia, are under a yellow warning for rain, storms, snow, or rough seas. The uncertainty increases significantly on Thursday, with western Andalusia, the area between the Ebro Delta and Nao Cape, and the central zone expecting substantial rainfall over the following days.
In addition to the heavy rainfall, there will be a significant drop in temperatures, with a few days resembling winter conditions. Tuesday and Wednesday will see temperatures fall, particularly in the southern regions, with daytime temperatures expected to be between 10-15 degrees Celsius in the interior and 15-20 degrees on the coasts. By Thursday, temperatures are expected to rise again, returning to normal levels. Due to the temperature drop, snowfall is expected at lower levels, with accumulations of up to 10 centimeters in mountainous regions. However, by Thursday, the snow is expected to be limited to mountain peaks.
