Four helicopters evacuated 150 people trapped in a four-star hotel and other remote structures after an avalanche, authorities in Italy said as heavy snow caused disruption across the Alps.

The Langtauferer Hotel, located near the Austrian border at 1,870 metres (6,135ft) above sea level, was not directly hit by the overnight avalanche, but the area was at extreme risk for more, said Katia Squeo, of the civil protection agency in Bolzano, Italy.

“The electricity was restored and the guests didn’t want to go, so the mayor ordered the evacuation,” Ms Squeo said.

“The avalanche risk is still present.”

The evacuation took place under clear conditions, with each helicopter ferrying seven people at a time to a school gym in nearby San Valentino, where they were fed.

The evacuees included 75 guests and hotel workers, local residents and tourists staying in other accommodations.

The whole village was cut off from the nearest major road, some 20 kilometres away, by the heavy snowfall and avalanche risk.

A structure at a closed educational facility was damaged in one avalanche, while the second storey of a house was destroyed in another, civil protection authorities said. The family was on the first floor and no-one was hurt.

The whole northern crest of the Alps bordering Austria was under the highest avalanche risk following an extraordinary snowfall of up to two metres (6.6ft), beating record levels dating to the early 1980s in some places, officials said.

The Langtauferer hotel boasts views of a 3,700-metre summit and advertises itself as being ideal for skiers, who can start their runs right outside the hotel door.

Martina Doene, the hotel’s manager, said the evacuees remained calm.

The civil protection agency said teams were also working to open roads to Val Senales, where thousands of tourists and residents had been isolated since Monday above Merano.

The town itself was protected by avalanche barriers and was at no immediate risk, Ms Squeo said.

Heavy snow has created dangerous conditions and disrupted transport across the Alps.

In France, the Chamonix ski area at the foot of Mont Blanc was closed due to what officials said was the highest avalanche risk. Several major roads and tunnels in the area were shut down.

In Switzerland, a road leading to the Gotthard tunnel towards Italy was shut.

Swiss public broadcaster SRF reported that the A2 highway near Gurtnellen was hit by an avalanche and was temporarily closed in both directions.

The Swiss ski resorts of Zermatt, Andermatt and Saas-Fee are cut off from the outside world due to the risk of avalanches.

Heavy snowfall has also hampered the arrival of participants at the annual World Economic Forum in the Swiss town of Davos.
