Gliding snow
- All elevations
Avalanche danger is moderate due to gliding snow. On steep smooth slopes in all aspects agove 2400 m, medium glide-snow avalanches are possible, indicated by glide cracks. No current risk of dry-snow avalanches, at most superficial layers or older drifts could trigger, usually only with large additional loading. A cautious route selection is advised.
Snow is irregularly distributed due to storm-strength winds. Crests and ridges are utterly windblown, gullies and bowls and zones behind protruberances are filled to the brim with drifted snow. Older drifts are often hardened, many surfaced are wind-compacted. The drifts are bonding well with the snowpack beneath them. Fresher drifts have weak intermediate layers, sometimes with graupel, and are prone to triggering. The fresh snow has settled well. At intermediate altitudes the snowpack is often moist down to the ground. The weight-load of the fresh snow reinforces the process of gliding over smooth ground.
Nocturnal hours: High-altitude clouds moving in from the west. Friday daytime: A sunny and mild day. At 2000 m: +2 degrees. Brisk to strong W/SW winds.
Saturday will be very sunny. The danger of dry-snow avalanches will not change. Danger of glide-snow avalanches will persist.
