MODERATE avalanche danger above the timberline due fresh snowdrift accumulations
On Wednesday, a few cm of fresh snow, intensely transported by strong winds. Weak layers occur inside the snowdrifts themselves and in some transitions to the lower layers.
MODERATE avalanche danger above the timberline due fresh snowdrift accumulations
MODERATE avalanche danger above the timberline, LOW below that altitude. Strong-to-stormy NW winds combined with snowfall are generating fresh snowdrift accumulations in gullies and bowls in all aspects near to and distant from ridgelines, also in sparsely wooded zones. Small-to-medium sized slab avalanches can be triggered even by one person. Exposed terrain is windblown.
On Tuesday night and on Wednesday, 5-15 cm of fresh snow is expected. Stormy NW winds are generating small snowdrift accumulations, often poorly bonded with the snowbase beneath them. In addition, more deeply embedded inside the snowpack are weak layers of faceted crystals bordering on melt-freeze crusts, weakening the entire snowpack thereby. They occur only in a few places, are generally triggerable by large additional loading.On Thursday, heavily overcast all day long, with intensifying precipitation over the morning, above 600-800 m persistent snowfall all day long. Strong to stormy winds.
Fresh snow and storm-strength winds are causing avalanche danger levels to rise.
