Moderate avalanche danger above treeline. Caution: snowdrifts!

Moderate avalanche danger above treeline. Caution: snowdrifts!

Above the treeline avalanche danger is moderate. Isolated avalanche prone locations are caused by trigger-sensitive snowdrift patches, particularly behind protruberances, in gullies, bowls. But due to daytime warmth, increasingly frequent naturally triggered wet-snow avalanches can be expected in steep terrain.

The old snowpack is generally stable and has a melt-freeze crust on the surface. Westerly winds have formed fresh, trigger-sensitive snowdrift patches. Also, the daytime warmth is made bonding between fresh fallen snow of last week and the snowpack fundament weaker. As a result of rising temperatures and diffuse radiation, the snowpack is settling.

In the southern massifs, some cloudbanks will pass through on Tuesday, the peaks will remain free and it will be dry. A moderate westerly wind will be blowing. It is becoming milder: at 2000 m, -2 degrees at midday.

On Wednesday, mostly sunny weather all day long in the southern massifs. Temperatures will rise measurably at all altitudes. The snowpack will settle further.
