Pericolo valanghe molto marcato sulle Alpi vallesane: in uno dei primi bollettini della stagione emesso dall’istituto* preposto parla di un grado quattro su una scala di cinque per quanto riguarda Champéry, Montana e Sierre.
La neve che è scesa in questi giorni, poi soffiata dal vento, si è depositata sui pendii. Slavine, si legge nel comunicato, si possono creare spontaneamente. Per questo motivo viene sconsigliato di praticare il fuoripista.
Allerta tre su cinque invece nella Alpi vodesi e bernesi. Nella notte fra sabato e domenica sono caduti dai 30 ai 50 centimetri di neve nel basso Vallese e al Nord delle Alpi. Nuove precipitazioni sono attese domenica in altitudine anche in Engadina.
