The passing of the storm Caetanothe third of great impact of this season, presents itself today alert fourteen autonomous communities –five of them on one level”orange” (significant risk) – mainly due to the strong wind and to intense sea stormwith waves of up to 5 meters in the Cantabrian Sea, reports the State Meteorological Agency (Aemet). The agency asks for extreme caution on coastlines with waves as well as objects that may fall from heights.
The “orange” alert has been activated in the four communities that face the Cantabrian coast (Galicia, Asturias, Cantabria and Basque Country) in anticipation of strong winds of up to 75 kilometers per hour and waves of 4 to 5 meters. Additionally, an “amber” warning has been activated on the Valencian Community, where the strongest gusts will reach 90 kilometers per hour inside the province of Alicante and in the southern interior of the province of Valencia.
There are “yellow” (risk) level warnings for gusts of up to 80 kilometers per hour in thirteen autonomous communities: Andalusia, Aragon, Asturias, Balearic Islands, Cantabria, Castile and León, Castile-La Mancha, Catalonia, Galicia, Murcia, Basque Country, La Rioja and the Canary Islands. In Asturias and Galiciaprecipitation can reach 40 liters per square meter, with snow above 1,100 meters.
Today’s alert map is supplemented by “yellow” level alerts in five Canary Islands (Gran Canaria, La Palma, La Gomera, El Hierro and Tenerife) due to the risk of thunderstorms and heavy downpours, which will mainly affect the peaks.

Cyclogenesis in the Atlantic
“On Thursday, a depression will appear near Greenlandinteracting and capturing another storm on Friday which will circulate at lower latitudes”, explains Samuel Biener, Meteored expert. “This will take place in the contact band between polar air and subtropical air, under a very intense polar jet. These conditions will favor a very powerful explosive cyclogenesis process between Friday and Saturday.”
The climatologist explains that “the situation could be potentially dangerous” in Northern Europe, because “the center of the storm could circulate very close to Ireland and Great Britain”. Spain will be far away, but it is “a very powerful and extremely deep storm for the time “, so its effects will also be felt in our country. The gusts will probably exceed 100 km/h in parts of Galicia, the Pyrenees and the Cantabrian Mountains, and It cannot be ruled out that speeds above 150 km/h may be exceeded..
On the other hand, the storm will bring a mass of abnormally hot air for the moment which will bring a new general rise in temperatures. “For Sunday, our cards predict daytime values from 25 to 27 ºC in the areas of Andalusia and the south of Extremadurawhile in cities like Santander either Bilbao they can leave above 23ºC. Be careful of the risk of fires on the Cantabrian slope,” warns Biener.

Finally, a front “fairly active and reinforced by a river of humidity“Associated with this great storm, it will reach Galicia throughout Sunday, leaving locally heavy and stormy rains that will extend to other points in the west-northwest and the Cantabrian slope. “The frontal system will cross the peninsula between Sunday and Monday, arriving already very weakened on the coasts of the Mediterranean”, concludes the expert from Weatherized.
