Gliding snow
- All elevations
Naturally triggered glide-snow avalanches in steep terrain and some snowdrifts on east and south-facing slopes
Naturally triggered glide-snow avalanches in steep terrain and some snowdrifts on east and south-facing slopes
Above the treeline moderate avalanche danger, below that altitude danger is low. Isolated danger zones occur from trigger-prone snowdrift accumulations on extended east-facing slopes, esp. at entries into gullies and bowls and behind discontinuities in the terrain, where 1 person can trigger a slab avalanche. In addition, on steep slopes in all aspects naturally triggered glide-snow avalanches reaching medium-size can trigger. Open glide cracks are indicators of imminent danger.
The snowpack base is stable by and large, only on shady slopes at high altitudes there are still reserves of cold. In steep terrain on smooth ground the snowpack glides over the ground at high altitudes. An area-wide snowpack exists only above the treeline.
On Wednesday, weather conditions will improve, temperatures rise, winds shift to westerly, clouds will pass through but mostly be no hindrance. Otherwise it will be sunny, moderate winds, brisk in the NE ranges, from W/NW. At 2000 m: 0 degrees.
Thursday will bring overcast skies, intensifying winds, but no precipitation. The snowdrift problem will recede. The gliding snow problem will persist.
