A large-scale low-pressure system, Bruna, is approaching the Atlantic Ocean and is expected to cause strong disturbances in Portugal and Spain starting from the end of this week. According to forecasts by the French meteorological agency La Chaîne Météo, the system will bring heavy rainfall, thunderstorms, and strong winds, with a possibility of local flooding in areas most exposed to precipitation. The low-pressure system is currently centered north of the Azores Islands.
The effects of the low-pressure system will be felt in Portugal starting from Sunday, November 8, with the intensity of rainfall expected to increase. The disturbances will then spread to vast areas of the Iberian Peninsula, with the impact of rainy fronts expected to continue throughout next week. In Portugal, accumulated rainfall may exceed 200 mm by Friday, November 13, particularly in the mountainous regions of the north and center of the country.
In addition to heavy rainfall, the low-pressure system will also bring strong winds and high waves to the Atlantic coast. Wind gusts may reach 80 kilometers per hour, and wave heights may range between four and five meters. In Spain, the regions most exposed to rainfall are Galicia, Extremadura, and western Andalusia, as well as the mountainous areas of the Central System.
Some weather scenarios suggest that between 200 and 300 mm of rainfall may be recorded locally in Spain between Monday, November 9, and Wednesday, November 11. This may increase the risk of flash flooding and flooding in some areas. The Portuguese Institute for the Sea and Atmosphere has confirmed that the low-pressure system Bruna will affect mainland Portugal starting from November 8.
The impact of the low-pressure system on Morocco is still uncertain, but forecasts by La Chaîne Météo suggest that some rainy fronts may extend to northern Morocco and the Atlantic coast next week. The city of Tangier is among the areas that may be affected by these weather developments. However, the probability of heavy rainfall in northern Morocco is currently less clear than in Portugal and Spain.
The French meteorological agency emphasizes that the impact of the low-pressure system on northern Morocco depends on the path of the system and the extent to which rainy fronts move southward. Further updates and forecasts will be necessary to determine the potential effects of the system on Morocco.
Residents in Portugal and Spain are advised to prepare for the potential impacts of the low-pressure system, including heavy rainfall, strong winds, and flooding. Authorities in both countries are likely to issue weather alerts and warnings in the coming days.
