The Portuguese Institute for Sea and Atmosphere (IPMA) has placed 12 of mainland Portugal's 18 districts under red warning (the most severe level on the scale, which alerts to a "meteorological situation of extreme risk"), from Thursday and at least until Saturday, due to the forecast hot weather, with a "persistent spell of extremely high temperatures, both daytime highs and overnight lows".
The red warning for heat will be extended from this Thursday to Beja, Évora, Portalegre and Santarém, in addition to Lisbon and Setúbal, and on Friday to Aveiro, Braga, Porto and Viana do Castelo, as well as Coimbra and Leiria.
