January 28th local time, according to the Swiss news agency Keystone-SDA, Switzerland closed a number of railway lines, involving Interlaken and Zermatt, due to the risk of avalanche in many places.
In addition, heavy snow weather has caused delays on several train lines, and it is expected that a large amount of snow will accumulate within 24 hours.
According to the Swiss Federal Institute of Forest Snow and Landscape, the risk of avalanches on the ridges in the northern Alps is particularly high, and there are more blizzards above 1,800 meters in many places than expected.
In places like the canton of Valais, snow over 2,000 metres is unstable and may have avalanches, and the Swiss Federal Institute of Forest Snow and Landscapes recommends against skiing in these areas.
