This season people can use the App to have a simpler way to report avalanches and see improved information. UPDATED
White Risk, is an avalanche prevention app developed by the WSL Institute for Snow and Avalanche Research (SLF) and has a new input interface for this year’s winter season.
The White Risk App has been available for 20 years and new features are added as they are developed.
“We want to make it even easier for people out and about in the mountains to send us this vital data,” says SLF avalanche warning officer Lukas Dürr.
By doing this, ski tourers, snowshoers, winter hikers and others make an important contribution to the avalanche bulletin as citizen scientists.
The data they provide goes directly into the systems of the avalanche warning service, giving its experts an even better picture of the current situation in Switzerland.
“This helps us to verify our current forecasts and so improve forecasts for the future,” added Dürr.

- Citizen science contributes to safety: Reported avalanches are incorporated directly into the avalanche warning systems and enhance the bulletin.
- More content, more precision: Now featuring avalanche bulletins for France, updated maps and more precise tour planning.
Anyone who witnesses an avalanche can mark the starting point on a map and enter further details such as its size and type.
This can be done from their location at the time.
Uploaded photos and videos provide additional information.
These should ideally include images of the entire avalanche as well as detailed shots of the area where it started.
The avalanche bulletin for France is also set to be published on White Risk during the winter season.
This describes the situation in the French Alps, the Pyrenees and Corsica.
