The northwest of the Iberian Peninsula receives, on the afternoon of this Thursday, the entry of a polar air mass that will cause a winter Friday, featuring the first autumn snowfalls, rains, strong gusts of wind and a temperature drop of up to 10 degrees.
As a result of a corridor between an area of low pressure in continental Europe and an anticyclone in the Azores that “is going to get stronger and closer to Spain”, as explained by the spokesperson for the State Meteorological Agency (Aemet), Rubén del Campo, the beginning of the weekend is presented with a general drop in temperatures in the northern half of the country and in the Balearic Islands.
The great barometric difference between both pressure systems will channel very intense winds from the northwest, wetter and colder than expected for this time of year. Winds from very high latitudes, beyond the Arctic Circle that will be established in the peninsula and that will cause a change of weather and “intense and persistent rainfall.”
A proof of this has been the strong downpour, between 17 and 19 liters per square meter, registered this morning in Madrid, which has even caused local flooding in Metro streets and tunnels.
Looking forward to Friday and Saturday Galicia, the Cantabrian communities, especially the Basque Country and northern Navarra, and the Pyrenees will be the most exposed to such rains. On the other hand, some points of Castilla y León, will also receive a rainy Friday and in Catalonia and the Balearic Islands storms will appear. In the rest of the country a dry environment.
As for the temperature, on Saturday it will wake up with a daytime decrease in the Mediterranean area and in the Balearic Islands, and they will rise somewhat in the rest of Spain. The minimums will continue to fall with values of 5 or 6 degrees in the Castilian-Leon capitals and 7 degrees in Madrid.
The gusts of wind will accompany the rainfall and the drop in temperature, with very strong gusts from the northwest in most of the country. Because of this, the waves will reach five or seven meters and, on land, the gusts could exceed 90 km / h in the Cantabrian Sea and reach 70 and 90 km / h in Álava, Navarra and La Rioja; 80 to 90 km / h in Aragon and about 100 km / h in Tarragona.
Sunday will bring lighter rainfall to the Cantabrian Sea and the Pyrenees and temperatures will rise, reaching 31 degrees in Malaga or 30 ºC in Alicante, Murcia, Córdoba, Seville and Huelva.
