The All Saints Bridge will be marked by abundant rains and falling temperatures, as advanced by the spokesman for the State Meteorological Agency (AEMET), Rubén del Campo, due to the irruption of an ‘río atmosférico ‘, caused by “the withdrawal of the anticyclone that will allow the arrival to the Peninsula of very moisture-laden winds, after traveling long distances over the Atlantic, giving rise to several rainy days in much of the Peninsula, especially in its western half.”
Del Campo has explained that these “humid and temperate wind flows” transport “large amounts of water vapor from tropical and subtropical areas to mid-latitudes”, which translates into “abundant rains”. As for temperatures, they will drop from Friday, although “they will be high for the time in the Mediterranean.”
Until then, this Wednesday and Thursday “The stable environment in general in Spain will still continue”, with morning fog banks and somewhat cloudier skies on the Mediterranean coast and the Balearic Islands, where there will be possible scattered stormy showers, which on Wednesday will be more likely on the coast of Almería and in Melilla and on Thursday in the Balearic Islands and coastal areas of the Valencian Community and Catalonia.
The origin of this rainy season is a #Atmospheric River (🐸👉https://t.co/GoFsHoEAQq) that provides a large amount of moisture from the tropics to our latitudes.

The rest of the country will be dominated by slightly cloudy skies and temperatures during these two days (Wednesday and Thursday) “will not experience great changes yet”, although, as Del Campo has pointed out, the arrival of a frontal system “will open the spigot for the change in the weather in the next few days and the arrival of the aforementioned atmospheric river “. Thus, the first rains will reach Galicia and nearby points of Asturias and León. In the west of the Galician community there will also be locally strong and persistent rains.
Del Campo has also alluded to “a marked difference between night and day”, with some weak frosts in moorland and mountain areas, while in the Guadalquivir Valley in the early afternoon it will exceed 26 or 27 degrees.
The Friday, this first frontal system will advance and leave rainfall in most of the Peninsula, although probably without yet reaching the Valencian Community, the Region of Murcia, eastern Andalusia and the Balearic Islands. On the contrary, on Friday in Galicia, west of Castilla y León, Extremadura and also in the extreme west of Andalusia, the rainfall will be locally strong and persistent, “and in some cases can accumulate more than 15 liters per square meter in just one hour or more than 40 liters per square meter in twelve works “, has alerted the spokesman.
Del Campo added that the Saturday The winds that are highly charged with humidity will arrive (the so-called ‘atmospheric river’), which will bring “a large amount of water vapor after having traveled long distances over the Atlantic and it will rain again in a large part of the country.” On that day, the rains will also reach the Mediterranean peninsular regions and the Balearic Islands, although in a weaker way than the rest of the territory since it will be the central area and the southern half of the Peninsula that will receive the most abundant rains.
In some cases, these rains will be accompanied by storms in some parts of southern Castilla-La Mancha and western Andalusia, where more than 50 or 60 liters per square meter could be registered throughout the day. “Abundant rains after a very dry October and Sunday will most likely again be a fully autumnal day in most of the Peninsula, with abundant rains especially in the western half although they will be less frequent in the Balearic Islands and points of the southeast “added Del Campo.

Very strong gusts of wind are also expected on Friday, Saturday and Sunday, especially in coastal and mountain areas. In terms of temperatures, the increase in cloudiness in the early hours of Friday will make the early hours of Friday noticeably warmer than in previous days. However, the greater presence of clouds will leave daytime temperatures “markedly lower, especially in the western half of the peninsula” and “the thermal amplitude will be greatly reduced”.
In the Mediterranean, on the other hand, daytime temperatures will rise a little on Friday, but on Saturday the roles will be reversed and they will fall while they will rise in the rest of the Peninsula. Already on Sunday, “the rise will be generalized”, as the spokesman has advanced, who added that the night frosts will disappear because “it will practically not fall below five degrees in any point of the Peninsula and on Sunday the maximum temperatures could even exceed 25 or 27 degrees in the regions bathed by the Mediterranean “.

The November 1st, public holiday throughout Spain, the uncertainty in the forecast increases although “it is possible that cloudy skies with rains will continue in much of the Peninsula, but, yes, already weaker and intermittent than in previous days, less intense and that will affect especially to the central and southern half, “according to Del Campo.
From Tuesday, Rainfall will be concentrated in the extreme north of the peninsula and the Balearic Islands, with clear skies in the rest and a marked thermal decrease that will be noticeable especially in the north of the peninsula, with possible frosts in the middle of the week in large areas of the interior and north. Therefore, it is expected that this episode will begin to remit from November 2.
