Il gelo attanaglia ancora vaste regioni a nord del San Gottardo con conseguente aumento dell'ammontare dei danni provocati a numerose colture dalle temperature per nulla primaverili degli ultimi dieci giorni.
Nella notte tra venerdì e sabato la colonnina di mercurio è scesa nuovamente abbondantemente sotto lo zero in numerose zone. A Visp, in Vallese, per esempio dove sono stati registrati meno 8,4 gradi. Notte glaciale anche a Berna (meno 6,4) e all'aeroporto di Zurigo, dove il termometro segnava meno 5,9 gradi.
Freddo fuori stagione anche nelle valli della Svizzera italiana, con meno 2,8 gradi a Airolo e temperature attorno allo zero anche più a sud. Il limite della neve resta attorno ai 1'200-1'300 metri di altitudine sia a meridione sia a settentrione della barriera alpina.
Il gelo tornerà anche la prossima notte, annuncia Meteosuisse: gli automobilisti sono invitati alla prudenza in special modo nelle prime ore dell'alba.
