The districts of Porto, Vila Real, Viana do Castelo, and Braga are under a yellow warning until 6:00 AM, the IPMA stated in a release.

The yellow warning is the least severe on a three-level scale and is issued whenever there is a risk to specific weather-dependent activities.

On 25 June on the mainland, the IPMA forecasts periods of very cloudy skies and potentially heavy showers accompanied by hail and thunderstorms, particularly in the Northern region until early morning.

Minimum temperatures will range from 15 degrees Celsius (Setúbal) to 18 degrees (Porto), while maximums will range from 21 degrees (Guarda) to 28 degrees (Évora).
