From cyclone Theta to heat: chaotic weather in Spain for the second half of November

The rainfall returns on the weekend from 14 to 15 to different parts of the country while the Canary archipelago will be affected by the influence of tropical storm ‘Theta’ even though stability will prevail again next week but also the mists will cover a good part of the Peninsula while temperatures will return to normal values, according to Meteorology Statal Agency (AEMET).

Specifically, the spokesperson for the AEMET, Ruben del Campo, has explained that the rainfall that arrived at the end of Friday in Extremadura and western Andalusia follow spreading Saturday from the west towards the interior of the Peninsula, although in a weaker and more dispersed way. The most intense, as highlighted will be those of Western Andalusia. Looking ahead to Sunday, rainfall will be intense in Galicia, From where will extend through the northwest third and, in a scattered way, they will reach other areas of the Peninsula except Andalusia and the mediterranean area.

Likewise, there is a probability of some fog banks in the central plateau and in the Ebro basin. Balearic Islands may have occasional showers, which will be more likely during the Saturday night and Sunday morning. In Canary Islands, the relative proximity of tropical storm ‘Theta’ will produce a increased cloud cover in the west as of Saturday, with rainfall in La Palma and, in isolation, they will affect other western islands.

The closest you get to the lucky islands will be during the first half of sunday, but very soon it will be absorbed by the atmospheric circulation of an Atlantic trough that will make you head north and get away from the archipelago. Late on Sunday ‘Theta ‘will lose its status as a tropical cyclone and throughout Tuesday it will cease to exist.

Meanwhile, its proximity to the Canary Islands will cause rough seas in the maritime zone from Madeira to the northeast of the Canary Islands, as well as winds in these maritime areas that may exceed 70 kilometers per hour and waves of up to 6 meters.

It will also cause effects on the ground but, according to the spokesperson they will be “fortunately very limited“because they will only provoke very strong winds, with streaks that can exceed 90 kilometers per hour in the peaks of La Palma and Tenerife. Del Campo adds that “it is common” for winds to reach those speeds or even higher on these peaks.

Nor does it rule out that in the north of the island of La Palma there may also be strong or very strong winds with tropical storm intensity, that is to say higher than 70 kilometers average speed Y more intense gusts of up to 90 kilometers per houras well as some showers on this island and, less likely, on the rest of the western islands.

The winds will also blow with strong intervals on Saturday and Sunday in Galicia and in the Cantabrian Mountains, as well as in high areas of the western Canary Islands.

Regarding temperatures, Del Campo points out that they will rise in almost all regions, so that there will be a “temperate” environment for the time, except in areas where fogs persist. Thus, it has specified that the 20ºC on the shores of the Cantabrian Sea, in Andalusia and in the Mediterranean area. Even locally they could be reached to be around 25ºC especially in the south of the Valencian community and inside the Murcia region as well as the Canary Islands.

With respect to Monday and Tuesday, the spokesperson predicts that cloud cover will gradually decrease until it is generally slightly cloudy, although there is a great probability of abundant fogs that will again affect the central plateau and the Ebro basin. On Tuesday they may be persistent in the northern plateau.

He has also indicated that on Tuesday intervals of strong wind on the coast of Galicia. Daytime temperatures will tend these days to ascend beyond normal values for this time of year. However, the spokesperson predicts a “stark contrast” between areas where fogs persist and where they soon lift or do not form.

For example, you said that in the surroundings of the Duero in Castilla y León on Monday and especially on Tuesday it will not exceed 10 degrees centigrade, Meanwhile in the south of this autonomous community can even reach 20ºC or overcome them, just like in the Cantabrian and in the Mediterranean area.

Even they will pass 25ºC in points of the Valencian Community, Region of Murcia and southern Andalusia, What are they very high values ​​for the timeAccording to the spokesperson, 5-10 degrees warmer than normal, with minimum temperatures that, although they will drop a little, will also be generally high for the season and only weak frosts are expected in mountain areas.

For the rest of next week there is a lot of uncertainty, but the spokesperson points out that starting on Wednesday again could be unstable, especially in the extreme north of the peninsula where there is a greater probability of precipitation, since it could reach un new frontal system which would later be followed by an influx of north winds.

This, if confirmed, would cause an entry of north winds that would mainly affect the northern third of the peninsula, with rains and showers, especially in Galicia, the Cantabrian area, the Pyrenees, northern Catalonia and parts of the Balearic Islands.

However, it does not rule out that They may also affect other areas of the Peninsula, such as Castilla y León or points in the rest of the northern half and the archipelagos. In this way, temperatures will tend to fall, especially in the north. Finally, the tendency for the period November 23 to December 6, 2020 according AEMET aim a a drier and warmer end of the month than the 20-year average, and an entry in December within the usual parameters.
