Spain is preparing for a new weather change. After several days marked by rain and low temperatures in different parts of the country, meteorologists are monitoring the arrival of an Atlantic low-pressure system that could bring significant rainfall starting on Sunday.
According to the latest weather forecasts, this low-pressure system will approach the Peninsula during the weekend and bring several rain fronts. In addition, it will be accompanied by a large atmospheric river, a current that transports large amounts of water vapor from subtropical areas and can increase the intensity of precipitation.
Weather models suggest that some areas could accumulate more than 100 liters per square meter during this episode. However, there is still some uncertainty about the exact trajectory of the low-pressure system and the areas that will receive the most intense rainfall.
Which areas of Spain could be most affected by the rains?
Forecasts indicate that Galicia, the Central System, the area around Grazalema and the Strait, as well as the southern face of the Pyrenees, could be some of the areas most affected by this new episode of rain.
In these areas, precipitation could be especially abundant due to the arrival of southwest winds, known as ábregos, which carry humidity and favor rainfall. In areas best exposed to these winds, accumulations could exceed 100 liters per square meter.
The Canary Islands will also be watching this weather change. Forecasts point to the arrival of an active front between Sunday and Monday, which could bring heavy showers, thunderstorms, and significant amounts of rain. In contrast, the Mediterranean slope and some areas of the Cantabrian coast would, in principle, be further away from the effects of this low-pressure system.
An atmospheric river will bring more humidity from the Atlantic
The arrival of this atmospheric river will be one of the main factors of this episode. It is an elongated and narrow current that transports large amounts of water vapor through the atmosphere. When it coincides with a low-pressure system and several fronts, it can favor abundant rainfall. The change in weather will begin to be noticed during the weekend, when the Atlantic low-pressure system approaches the Peninsula and sends several fronts. The most significant rains could arrive during the first half of next week.
In addition, temperatures will remain relatively mild for this time of year due to the arrival of air masses of subtropical origin. For now, meteorologists are still awaiting the evolution of the models to specify the trajectory of the low-pressure system and the amount of rain that could fall in each autonomous community.
