Since Saturday evening, the ski resort of Zermattexternal link in canton Valais has been cut off due to risk of avalanches. The road and railway line between Täsch and Zermatt is still closed due to avalanche danger and rockfalls, the tourist office said on Tuesdayexternal link. The duration of the closure is unclear. This is the second time the resort has been cut off by heavy snow this month.
Some 9,000 tourists have been blocked at Zermatt since Saturday. Helicopter services out of the resort are heavily oversubscribed. On Sunday, 500 people flew out and 300 arrived.
