In Switzerland it will continue to snow until around Monday evening, reports SRF Meteo. The snow line falls in Ticino at 600 to 800 meters. This means that there is still a great danger of avalanches.

The Furka car transport service, however, was suspended until further notice on Sunday. The reason for this was the closure of the road between Realp and Hospental due to the danger of avalanches.
