Storm Gérard, the seventh of the season, is ahead of Storm Fien and will affect Spain this Monday with wind, waves, snowfall and rain, phenomena that will put some 40 provinces across the country at risk, according to the forecast of the State Meteorological Agency.

Specifically, this Monday the wind will be at significant risk (orange) to A Coruña and Lugo, and at risk (yellow) to Teruel, Zaragoza, Asturias, Cantabria, the Balearic Islands, Albacete, Cuenca, Guadalajara, Barcelona, ​​Tarragona, Ourense, Madrid, Murcia, Guipúzcoa, Vizcaya, La Rioja, Alicante, Castellón, Valencia, Almería, Granada, Burgos, Ávila, León, Zamora, Soria, Valladolid, Segovia, Zamora and Palencia.

The Balearic Islands, Barcelona, ​​Tarragona, Alicante, Castellón, Valencia and Málaga, as well as the autonomous city of Melilla, will also be at risk from waves, but at a lower level.

Also this Monday the snow will affect different areas, like Huesca, which will be at significant risk, like Navarra, while Zaragoza, Burgos, León, Palencia, Soria, Zamora, Barcelona, ​​Girona, Lleida and La Rioja will be on lower level alert.

The rain will also put Asturias, León, Pontevedra, Navarra, Álava, Guipúzcoa and Vizcaya at risk, while Cantabria will be at significant risk due to the same phenomenon.

All these alerts coincide with the entry of the Gérard storm, which has anticipated the Fien storm and will be felt in Spain this Monday, in which, in general, overcast skies are expected, as will be the case in the northern half of the peninsula , with persistent and widespread rainfall in Galicia, the Cantabrian area and the central and western Pyrenees, which may be locally strong in the Cantabrian coastal areas and surroundings.

Rainfall will be less likely the further southalthough in the environment of the Central and Iberian systems they may have a certain persistence, the AEMET has detailed.

In addition, in the southern half of the Peninsula, intervals of medium and high clouds are expected at first, increasing throughout the day to cloudy or covered and without ruling out some weak and occasional precipitation in mountainous areas. In the Balearic Islands and points of the central Catalan coast, an occasional shower is not ruled out and in the Canary Islands cloudy skies and precipitation are expected in the north of the islands with greater relief, and with cloudy intervals in general in the rest.

On the other hand, the snow levels will be located in the northwest of the peninsula at 1,200/1,500 meters, rising to 1,800/2,000 meters. In the rest of the northern half it will be at 700/900 meters, rising to 1,300/1,500 in the Pyrenees — where 30 centimeters can accumulate at these levels in the western Pyrenees — and 1,600/1,800 meters in the rest.

Regarding the temperatures, the daytime temperatures will not change or will rise in the west and northwest of the peninsula, while they will drop locally notably in the southeastern third, the Balearic Islands and the surrounding Pyrenees. The minimum will increase in the northwest and decrease in the east and southeast. In addition, few changes or a slight decrease are expected in the Canary Islands.while weak frosts are expected in the north and east of the peninsula, more intense in the Pyrenees.

In addition, the wind will be from the west in the Peninsula and the Balearic Islands, strong in the northern and eastern thirds of the Peninsula, and with very strong gusts in mountain areas, as well as in the northern plateau, the Balearic Islands and the surroundings of Alborán. Likewise, very strong intervals are forecast in the north of Galicia and trade winds in the Canary Islands.

Specifically, the strong winds will give rise to a maritime storm throughout the day in the Cantabrian area, with winds that can occasionally exceed 80 km/h and waves of between six and eight meters.

MOST ADVERSE STORM WITH FIEN

After Gérard’s passage, the most adverse part of the winter storm will correspond to the Fien squall, the sixth of the season, which will form in the early hours of Tuesday and will be accompanied by snowfall at low levels in the center and northern half, where they could even see flakes at sea level.

According to a special notice from the AEMET, as of this Monday the interaction of the powerful Atlantic anticyclone centered to the west of the Azores, with the deepening of the Fien squall, to the south of the British Isles, will lead to the intensification of the Atlantic flow from the west and northwest, making it stronger, wetter and colder.

This meteorological situation will cause a storm of wind and sea in the Peninsula and the Balearic Islands, and of snow and rain in the northern half of the peninsula, which will continue for a good part of the week.

Thus, on Tuesday, January 17, the irruption through the northwest of the peninsula of an air mass of maritime-polar origin, very cold, is expected, which will spread in subsequent days to the rest of the Peninsula and the Balearic Islands, giving rise to intense winds from the northwest, and rainfall that will tend to be generalized, and that together with a pronounced thermal drop, will occur in the form of snow at levels that can drop below 500 meters with the possible irruption of a mass of arctic origin along on Wednesday and Thursday.

Likewise, during Tuesday and Wednesday, precipitation is expected to occur almost universally in the Peninsula and the Balearic Islands, being less likely in the peninsular Mediterranean area. In addition, a drop in the snow levels on Tuesday will mean that said precipitations will be in the form of snow at low levels, without being discarded at sea level in the Cantabrian area on Wednesday. During these days the very strong gusts of wind will continue, especially on Tuesday.

Next Thursday, January 19, the most significant will be the snowfall at low levels in the northern third of the peninsula, while on Friday the 20th the entry of humid air from the northwest will continue but it is likely that it will gradually be less cold, with the consequent rise in snow level. The most relevant of this day will be the rains of the extreme north of the peninsula.

The AEMET has specified that it is probable that on Saturday the 21st the replacement of the Arctic air mass with a more temperate one will be consolidated, thus ending this winter episode.
