Yellow weather warnings issued for eleven mainland districts
The Portuguese Institute of the Sea and the Atmosphere (Instituto Português do Mar e da Atmosfera or IPMA) has placed 11 mainland districts under a yellow warning for rain and thunderstorms. The alert, which is the least severe on a three-level scale, warns of heavy showers and wind gusts between 70 and 90 km/h. The warnings are in effect throughout the day across various regions, including Porto, Braga, and Viana do Castelo.
A red warning is the highest alert level issued by Portugal's weather agency, the Portuguese Institute for the Sea and the Atmosphere (Instituto Português do Mar e da Atmosfera or IPMA), used when conditions pose a very high risk to life and property. Under a red warning authorities may close roads, suspend transport and advise people to avoid coastal and flood‑prone areas, so follow civil protection instructions during the Friday–Saturday storm period.
