The Snowdesk map: Swiss warning regions coloured by danger level, with the Martigny–Verbier bulletin open on its wind slab problem.

Current conditions

The official bulletin, on one map

Every warning region, coloured by the day’s danger level. Open one to read the bulletin as the warning service issued it. Zoom in and the day’s avalanche problems are painted on the ground, on the aspects and elevations they affect.

The Verbier Backside route off Mont Fort in Snowdesk: the line coloured by slope angle over the day’s problem terrain, its elevation profile, and a point card reading a 35°+ fall-line descent on very steep 35–40° ground.

Route planning

See the ground your line crosses

Draw a route or upload a GPX and see the slope angle under every metre of it, the climbs and descents on its profile, and the day’s problem terrain beneath the line. Try the example route, no account needed.

No score and no verdict: the judgement stays with you. Full terrain analysis covers Switzerland today.

Trips

One link for the group

Pick the route, the day and a meeting point. The trip carries the forecast and the danger level for each day you might go, and anyone you send the link to can save it.

The bulletin is the authority

Snowdesk does not write avalanche forecasts. Every danger level comes from the warning service that issued it, shown as they wrote it. The route analysis reads slope angle, and the problem terrain is the bulletin drawn on the ground — neither is a verdict, and a route with nothing marked is not a safe route. None of it replaces avalanche training, a transceiver you can use, and partners who can use theirs.

Avalanche bulletins from SLF (Switzerland), Météo-France (French Alps) and ALBINA (Tyrol, South Tyrol, Trentino). Weather forecasts from Open-Meteo.
