MODERATE avalanche danger above the treeline
MODERATE avalanche danger above the treeline
Avalanche danger above the treeline is moderate, below that altitude danger is low. Danger zones due to trigger-sensitive snowdrifts occur in E/S terrain. Frequency of danger zones increases with ascending altitude, as snowdrifts deepen the snowpack can reach larger size, mostly with large additional loading.
On the weekend, stormy NW winds were blowing which transported the fresh snow of recent days and deposited it as brittle, bonded snowdrift patches in forested zones. Trigger-sensitive snowdrift accumulations occur moslty inside the drifted masses. At higher altitude the drifts were deposited atop loose fresh snow, bonding to the snowpack is poor. Summits and exposed zones are utterly windblown. At low altitudes the snowpack stability has improved due to the drop in temperatures. Between Sunday and Monday, surface hoar formed.
Tuesday will bring very sunny and cold weather. Outside of the haze the air is dry and cleare, with outstanding visibility. Winds will be light to moderate from the northeast. At 2000 m: -11 degrees.
Winds will shift to southeasterly. Snowdrifts will accumulate on north-facing slopes.
