Il vento è spirato sulla Svizzera italiana a partire dal tardo pomeriggio di domenica con raffiche di velocità compresa tra gli 80 e i 100 chilometri all’ora sul Piano di Magadino.
Secondo Luca Nisi di Meteosvizzera a Locarno-Monti, non si tratta di un fenomeno frequente ma nemmeno raro: queste velocità si misurano mediamente 3-4 volte all’anno. In altitudine nella notte tra domenica e lunedi si sono raggiunti i 125 chilometri orari di massima. Si tratta dell’effetto della ricaduta favonica.
Lunedi il vento continuerà a spazzare in modo irregolare il Sud delle Alpi e da martedi l’episodio si esaurirà. La velocità del vento più elevata a basse quote in Ticino è stata registrata il 27 dicembre 1991 con 120 orari.
