Glide-snow and snowdrift problem in the Prealps
Glide-snow and snowdrift problem in the Prealps
Avalanche danger in the Bavarian Alps is low. Gliding snow is the main problem. On very steep slopes with smooth ground in all aspects, isolated naturally triggered glide-snow releases (small-to-medium) are possible. Glide cracks are indicators of potential danger. Apart from that, freshly generated snowdrift accumulations can trigger a small slab even by minimum additional loading. Danger zones occur above the timberline near near ridges on north and east-facing slopes and in wind-loaded gullies and bowls. Frequency of avalanche prone locations increases with ascending altitude. Danger of falling outweighs that of being buried in snow from avalanches.
The old snowpack surface is moist, often wet down to ground level, which reinforces the gliding movements of the entire snowpack. The old snowpack is icy, melt-freeze encrusted and capable of bearing loads. Only small amounts of fresh snow are being transported by westerly winds in exposed terrain, generating small, often trigger-sensitive drifts on leeward slopes. Backcountry tours usually require passages where skis must be carried.
Until the weekend, avalanche danger levels are not expected to change significantly.
