According to the Portuguese Institute of the Sea and Atmosphere (IPMA), the north and centre of Portugal will feel the effects of the frontal system associated with Storm Benjamin, especially between this afternoon and early Thursday morning. Wind intensity is expected to increase from the west, with gusts that could reach 95 kilometres per hour (km/h) in the highlands.

Precipitation will be heavy at times, especially in Minho and Douro Litoral, while being light in the south, the IPMA reported.

According to the IPMA (National Institute of Meteorology), due to this situation, yellow weather warnings for rain have been issued for Minho and Douro Litoral regions, and warnings for strong winds in the highlands of the North and Centre regions.

The districts of Bragança, Viseu, Porto, Guarda, Vila Real, Viana do Castelo, and Braga will be under warning between 9:00 PM today and 6:00 AM Thursday due to the forecast of southwesterly winds turning to northwesterly, with gusts of up to 95 km/h in the highlands.

The IPMA also issued a yellow warning between 9:00 PM today and 6:00 AM Thursday for the districts of Viseu, Porto, Vila Real, Viana do Castelo, Aveiro, and Braga, but due to persistent rain, turning into showers, sometimes heavy, and possibly accompanied by thunderstorms.

"In the coming days, the weather on the continent will continue to be characterised by a westerly flow, transporting an air mass with a high water vapour content, which will produce heavy and persistent precipitation, especially between Friday the 24th and Saturday the 25th," the Portuguese meteorological institute also indicated.

The Central region is most likely to record the highest accumulated precipitation during this period, with values ​​between 50 and 100 mm, a situation that could extend to the North.

On Sunday the 26th, a decrease in weather conditions is expected in the North and Central regions, but with the frontal system moving south, where precipitation may be temporarily more intense until early afternoon.

Due to the "spatial and temporal uncertainty associated with this meteorological situation," the IPMA advises monitoring the situation and the weather warnings that will be issued in the coming days.
