Temperature di 15 gradi e anche oltre oggi, giovedì, a mezzogiorno in alcune località della Svizzera: alla vigilia dell'ultimo dell'anno non si ha per nulla la sensazione di essere in inverno. E il record per la località più calda è ticinese: ad Acquarossa, in Valle di Blenio, si sono raggiunti i 18,8 gradi.
A Robbia, in Val Poschiavo (GR) a 1'078 metri sul mare, si sono toccati i 16,2 gradi, ad Aesch (BL) i 15,8 gradi e a Wohlen (AG) i 15,2 gradi: lo ha comunicato Meteonews su Twitter. Nelle città come Zurigo, Basilea, Berna e Ginevra la soglia dei 15 gradi è stata sfiorata o raggiunta in giornata.
Poiché fino ad alta quota il clima è mite, l'Istituto per lo studio della neve e delle valanghe ha posto in atto il grado di pericolo 4 per la dorsale alpina settentrionale e il Vallese come così come per i Grigioni settentrionali, la Silvretta e Samnaun. Anche in montagna l'aria è stata particolarmente mite per la stagione con quasi 11 gradi a Les Marécottes (VS), Adelboden (BE) o La Brévine (NE).
