Swiss avalanche bulletin archive

Historical evidence only. The selected SLF bulletin is dated 2026-04-30. Never use this page for current avalanche, snowpack, route or travel decisions. Check the current official SLF bulletin before any mountain journey.

Evidence found: 0 of 3 bulletin features match this dated view.
Source coverage: 362 approved dated R2 snapshots from 2024-11-01 to 2026-04-30; dates within that range are not assumed to be continuous. This page is displaying the 2026-04-30 source object, imported 2026-08-08.
What this means: The page reproduces source-labelled regions, danger ratings, avalanche problems and narrative environment fields published for the selected historical bulletin date.
What this does not mean: It is not today's bulletin, a local slope assessment, an access decision or a forecast for a ski area. Historical ratings must never be used for present travel or safety decisions.

No bulletin feature matched these filters. This is a filter result, not evidence that the selected place had no avalanche hazard.
