The Swiss ski ski resort has been cut and tourists and residents were invited to stay inside in the French Tignes station due to heavy snow in the Alps on Thursday.
The mayor of Tignes, Serge Revial, said that there was a high risk of avalanches and “we had to make the decision to protect people”, after more than a meter of snow was thrown in the city.
Although snow is not uncommon in the Alps in April, the disturbance has left thousands of houses in the Savoy region of eastern France without power.
In neighboring Switzerland, the Simplon pass in Italy and the Grand Tunnel of St Bernard were closed to traffic, while two cantons were seriously affected.
In Valais and Bernese Oberland, tourists heading for ski holidays were affected by the disturbance.
The road and rail roads were cut in the Zermatt station in the southern canton of Valais; Food was cut throughout Thursday and mobile telephone networks were seriously disrupted.
The queues were built outside the only open supermarket in the city, according to Swiss Media.
The Alertetswiss application warned the risk of avalanches and trees falling into Valais as well as major disturbances for transport. The schools were closed for the day in the city of Sion.
People traveling in the Easter region were invited to delay their trips until Saturday. Local police have urged people to stay at home if possible.
South of Zermatt, power outages were reported in 37 of the 74 municipalities in the Aosta Valley in the northwest of Italy, and a bridge collapsed in Biella in the neighboring Piedmont.
The biggest problem in the northwest of Italy was heavy rains, while the rivers broke out their banks and a 92-year-old man would have drowned because of the floods in his house in Monteu da Po near Turin.
A torrent of water was cascade in the streets of the village, in hills near the Po river.
Red alerts have been issued in several valleys, but the largest concern was for PO where river levels should peak within 24 hours.
Meteorologists said that in some regions, more than 20 cm of rain had dropped in 36 hours and that extreme peaks had been recorded of even higher levels.
“It has been raining constantly for days, very, very hard, although it is arrested now,” said Manuela, a resident of Turin, 33, at the BBC.
“Two rivers, the PO and the Dora, near Turin, broke out their banks. The city is well but they had to close several bars and restaurants near the River in Turin.”
