The end of the meteorological calm
After a period of calm weather in the Iberian Peninsula, the State Meteorological Agency (AEMET) has warned of the arrival of the storm Caetano, a phenomenon that will radically modify weather conditions. Temperatures are preparing for a significant drop, while rain will become more frequent and snow will begin to make an appearance in the mountainous areas of northern Spain.
Ongoing weather phenomena
The formation of Caetano in the northern Cantabrian Sea is linked to a decrease in the polar jet stream, which acts as a catalyst for a series of low pressures. These conditions will generate intense rain, especially in the eastern area of the Cantabrian, Navarre and the Pyrenees, with a snow level that will initially be above 2000 meters.
Impact of snow on the mountains
The snowfall will be one of the most prominent aspects, with its incidence concentrated in the main mountain systems. The Pyrenees and the Cantabrian mountain range will be the most affected areas, and as the days go by, the snowfall could drop to lower altitudes, especially in the north of the peninsula.
An active weather front on the horizon
Starting Thursday, the AEMET anticipates the arrival of a more active front that will move eastward. This will bring more abundant rain in Galicia, the Cantabrian Sea and the areas of the northern slope of the Pyrenees, with snowfall that will extend towards the Iberian system and the central system, where the accumulation will be notable at high altitudes.
The Mediterranean escapes the cold
Unlike the rest of the Peninsula, the Mediterranean region will remain away from the coldest temperatures, with highs that could exceed 22-24º C. Meanwhile, temperatures in the northern half will continue a downward trend, creating a more wintery atmosphere.
Wind conditions and instability
In addition to precipitation, wind will play a crucial role in the weather dynamics over the next few days. Strong gusts are expected on the Cantabrian coast, in the northeast of Catalonia and in mountainous areas in the east, with intense winds that could affect conditions in the coastal areas of Galicia and the Balearic Islands.
The instability remains
As Friday progresses, the frontal system will continue its path towards the Gulf of Genoa, leaving a trail of instability across the Peninsula. Rain will be concentrated mainly in the northern third, while temperatures will continue to drop considerably, consolidating a typically wintry atmosphere.
Despite the drastic changes in weather conditions, Spain will not face the extremely cold temperatures affecting other regions of Europe, staying safe from arctic temperatures. However, the transition to a more unstable climate will be evident in the coming days.
