Galicia faces an episode of heavy rains and strong winds Driven by successive Atlantic fronts. The humid west-southwesterly flow will leave very cloudy or overcast skies, persistent showers on the Atlantic coast, and a stormy sea that will require extreme caution along the coast.
According to the forecasts of the AEMET and Meteogalicia, the warnings will gain importance as the hours go by: yellow due to rain and coastal phenomena, orange by precipitation, wind and rough seas in the most adverse sections, with very strong gusts and significant waves.
Active alerts and episode schedule
During the opening day They wait persistent rainfall In Galicia, especially in the western half, there will be locally heavy showers and the possibility of thunderstorms. The AEMET maintains warnings. yellows by rain and coast and contemplates its climbing to orange from the afternoon in the sections of greatest impact.
The situation will tend to intensify at night, when the front becomes well organized and the southwesterly wind picks up. Meteogalicia forecasts a slight drop in temperature in the early stages, as well as fog banks in valleys and mountain areas which may reduce visibility.
With the advance of the fronts, adverse weather will extend towards the Cantabrian SeaAsturias, Cantabria, and the Basque Country will issue warnings in the coming hours/days, maintaining instability in the northern peninsula.
The Atlantic circulation will dominate the pattern, with a step of successive fronts which will see renewed showers and wind. This scenario links to a phase Negative NAO, which favors the arrival of storms and rivers of humidity to latitudes of the Peninsula.
Where and how much it will rain
In chained episodes, the models contemplate that western Galicia can exceed 100-200 l/m² over several days, especially if the moisture jet remains anchored. High values have already been recorded at stations such as Poio, Rianxo, Fornelos de Montes or Redondela, with notable daily peaks.
Outside Galicia, the rain will spread throughout the Cantabrian Arch and will reach more irregularly Castilla y Leon and nearby areas. In the rest of the country, rainfall will be lighter and more scattered, with the Mediterranean often on the sidelines.
Cloudiness will be abundant, with overcast skies on the Atlantic slope and the western Cantabrian Sea. There will also be intervals inland, while in the alboran sea and sectors of the eastern peninsula will be clearer.
Very strong and stormy wind on the coast
The wind of the west-southwest will take center stage, with gusts that could exceed 60-90 km / h in large areas and peaks close to or higher than 100 km/h on exposed peaks and capes. In recent episodes, 127 km/h at Punta Candieira (Cedeira), 118 km/h in Burella and more than 110 km/h in Penedo do Galo (Viveiro).
At sea, it is expected tidal wave to strong tidal wave with combined sea. Around Stake of Bars waves can be seen around 4 meters in intermediate phases, reaching ranges of 5 7-m in the most adverse moments in the Cantabrian and northwest.
With this scenario, the following will remain active: coastal warnings, Especially in To Mariña and sections of A Coruña, with time windows that can extend into the afternoon and early morning. Navigation and activities in ports and breakwaters will require attention to official bulletins.
Inside, the wind will also be noticeable in mountainous areas from the north and in valley passes, with gusts that will complicate driving and increase the risk of falling branches or poorly secured elements.
Temperatures, cloudiness and fog
The maximum temperatures Temperatures will tend to drop in the northwest and the Cantabrian Sea, with a cooler and wetter atmosphere. In contrast, the south and east of the peninsula may maintain high values. higher than normal for the time, with particularly summery thresholds.
They will be formed fog banks mornings and evenings in Galicia, the Pyrenees and western mountain areas, which locally could persist much of the day and complicate visibility on crossings and country roads.
AEMET anticipates that the passage of fronts will bring heavy cloudiness in much of the northern half, with more frequent clearings as frontal systems advance and weaken towards the center and east.
Looking ahead to the next few days, the pattern of Atlantic instability, with new fronts that will bring renewed rainfall to Galicia and the Cantabrian region. The intensity of the showers is not ruled out. vary by day depending on the position of the jet and the dynamics of the storms.
Water resources: relief for municipalities in pre-alert and recommendations
The arrival of these rains will mean a respite from the shortage that carry several river systems and urban supplies. The Xunta maintains the pre-alert for moderate shortage en 45 municipalities linked, among others, to the Verdugo, Lérez, Grande and Anllóns rivers, and the estuaries of Vigo, Baiona and the coast of Pontevedra.
The affected municipalities include, among others, Mud, Bueu, Campo Lameiro, Cerdedo-Cotobade, A Estrada, Forcarei, Marín, Meaño, Moraña, Poio, Ponte Caldelas, Pontevedra, Sanxenxo; in A Coruña and Lugo: Cabana de Bergantiños, Camariñas, Laxe, Muxía, Vimianzo, Zas, Arteixo, Carballo, Cerceda, Coristanco, Culleredo, A Laracha, Malpica, Ponteceso, Tordoia; and in the Vigo area and surrounding areas: Baiona, Cangas, Fornelos de Montes, Gondomar, A Lama, Moaña, Mondariz, Nigrán, Pazos de Borbén, Redondela, Soutomaior, Vigo, Vilaboa, A Guarda, Oia and O Rosal.
La Technical Office of Seca recommends that administrations reduce non-essential consumption (sweeping, ornamental irrigation) and that citizens do a responsible use of water (shower versus bath, appliances in eco mode). Reservoirs such as threshing floors have been under surveillance, although the upcoming rainfall will help replenish reserves.
Currently, the resources of Galicia Coast are located around the 42,4%, while the basin of the Miño-Sil around the 59,9%, figures that could improve if several days of effective and persistent rain are consolidated.
In view of this episode, it is advisable to follow the , check roofs and drains, secure objects on balconies and in gardens, and take extreme care caution on the road due to puddles, mud, and crosswinds. On the coast, avoid walks along dikes and areas subject to waves.
