Snowpack Structure

The snowpack was able to settle well. The old snowpack at high altitudes is being weakened in places by faceted crystals, elsewhere the snowpack is hardened and icy. Some snowdrifts at high altitudes were deposited atop the hardened old snowpack surface or on a layer of surface hoar.

Weather Synopsis

On the southern flank of the Alps and in general in high alpine regions, sunshine will soon prevail. In the afternoon, cloudless skies will increase, the winds slacken off (stormy only on the eastern rim of the Alps). At 2000 m: -7 degrees. Temperatures will gradually rise.

Tendency

Amid intermediate high-pressure influence, sunshine will often dominate on Wednesday and it will be quite mild. Winds will be blowing at light to moderate strength from westerly direciton. At 2000 m: 0 degrees. No significant change in avalanche danger levels is expected.

Avalanche Activity

Caution on north-facing slopes: persistent weak layer

Isolated danger zones on extremely steep north-facing slopes. Stormy (sometimes gale) winds will generate small snowdrift patches in eastern and southern aspects Older snowdrifts can trigger by large additional loading.
