The women were skiing on a path typically used by snow ploughs slightly above the groomed run, when a wet avalanche was released above them. The women noticed the avalanche and tried to outski it but both got swept away. One of the women, aged 54, was only partially buried and was found straight away by mountain rescue. She was flown with mild injuries to a hospital in Zams, Austria.
The other woman, aged 53, was carried for about 130ft (40m) and was fully buried. She was only found about an hour later through the help of avalanche search dogs. She was resuscitated and helicoptered to a specialist hospital in St. Gallen, Switzerland, where she succumbed to her injuries.
Rescuers from Switzerland and Austria were called to the search and the canton of Grisons/Graubünden is investigating the incident.
The avalanche danger for most areas in Switzerland are currently at Level 2 'moderate' but were judged to be Level 3 'considerable' for wet avalanches on Saturday for the Samnaun region by the Swiss Avalanche Institute 'SLF'. A subsequent wet avalanche on Sunday, April 30, 2023, slid onto the groomed runs in Samnaun in the afternoon. Dozens of rescue workers searched the snow according to a report by Swiss newspaper Blick, but it appears that no-one had been injured.
Wet avalanches are very dangerous this time of year when warmer temperatures can cause liquid water in the snowpack, which weakens the bonding of the different snow layers. Water accumulates and increases the instability, in particular where you encounter poorly bonded, non-homogenous snow layers of varying grain sizes. Often these types of avalanches are triggered spontaneously and not through other snowsport participants.
