Mainland Portugal and the Madeira archipelago will be affected from today by wind, rain, and rough seas due to Storm Claudia, which is expected to begin affecting the Minho region by the end of today and then spread to all districts of the mainland.

According to IPMA (Portuguese Institute of the Sea and the Atmosphere), “the highest accumulated rainfall is expected on the North and Central coast and in mountainous regions, potentially exceeding 150 mm in some places by Sunday.”

“The peak wind intensity is expected to be reached on Thursday,” with gusts that “could reach values ​​of around 90 km/h on the coast and around 120 km/h in the highlands.”

According to the Institute, the Claudia depression, which is expressed at altitude, is expected to be part of "a vast, complex low-pressure area over the North Atlantic and is predicted to remain almost stationary until the end of the week."
