Moderate avalanche danger prevails. Above the treeline older and freshly generated snowdrift accumulations in E/S aspects, particularly at entries into steep gullies and bowls can be triggered, often by minimum additional loading. Due to daytime warmth, increasingly frequent naturally triggered wet-snow avalanches can be expected in steep terrain in all aspects.
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. With the daytime warming and solar radiation the snowpack quickly becomes moist and instable.
Wednesday will begin sunny, then convective clouds will accumulate in the Northern Alps, while in southern regions sunshine will dominate. Winds will be moderate from the south, temperatures will rise. At 2000 m: +4 degrees.
Thursday will be variably cloudy, not much precipitation is expected. Avalanche danger will recede slightly.
