Macugnaga Buried by Up to 1.5 Meters of Snow in 24 Hours as Avalanche Alert and Travel Disruptions Persist

A moist Mediterranean flow from an Italian low drove the rare mid‑March snowfall over the southern Alps.

Overview

  • Authorities keep the avalanche warning at orange for northern Piedmont while safety inspections and snow clearing continue.
  • Schools and kindergartens in Vanzone con San Carlo are closed on Monday due to unsafe routes for students and staff.
  • State Road 549 toward Macugnaga was temporarily shut between Colasca and Castiglione, and the Vigezzina rail service is suspended.
  • Antrona Valley reports a snow emergency with widespread power outages after fallen trees and heavy snow damaged power lines, and residents are urged to limit travel.
  • The intense system also produced standout totals across the region, including a 116‑centimeter 24‑hour record at Switzerland’s Bosco station.
