Stable snowpack, melt-freeze crusts dominate. Due to warmth, weak layers have been decimated in old snowpack. Clouds dominate, sunshine will be rare. A few snowflakes or raindrops. In the afternoon, improving visibility. Little wind. At 1500 m: 2-5 degrees. Springlike situation starting on Saturday, slight daytime danger cycle. 2021-02-18T17:00:00+00:00 avalanche-warnings.eu 2021-02-18T23:00:00+00:00 2021-02-19T23:00:00+00:00 2 1 old snow triggerable in transitions from shallow to deep snow, in shady and high alpine terrain wet snow slight daytime danger cycle of naturally triggered avalanches Avoid very steep terrain at high and high alpine altitudes Avalanche danger above 2000 m is MODERATE, below that altitude danger is LOW. Small-to-medium slabs can be triggered in E/N facing slopes (most recent snowdrifts + old-snow problem, respectively) in very steep terrain often by minimum additional loading. Transitions from shallow to deep snow and entry points into steep gullies are the most critical. Slight daytime cycle can lead to isolated glide-snow and small loose-snow avalanches on steep sunny slopes at low and intermediate altitudes. Melt freeze crusts often dominate. On sunny slopes they can transform to firn. West-facing slopes, plateaus and combs are often utterly windblown. Gullies with older drifts are filled. Powder still exists on shady slopes in in wind-protected zones. The most recent snowdrifts from the early part of the week have not bonded well with the old snowpack at high and high alpine altitudes. On north-facing slopes, isolated weak intermediate layers are still evident inside the old snowpack. Visibility is generally good, high peaks can be partly veiled in clouds. Intermittent sunshine. Little wind. At 2000 m: -2 to +2 degrees; at 3000 m, -5 degrees. The snowdrift-problem / old-snow problem will recede further. Slight daytime cycle / spring situation on the weekend. Air is very dry, delaying the firn, the nights are still longer than the days, thus cooling the snowpack. 2021-02-18T17:00:00+00:00 avalanche-warnings.eu 2021-02-18T23:00:00+00:00 2021-02-19T23:00:00+00:00 2 old snow in gullies, steep bowls, triggerable in transitions from shallow to deep snow gliding snow in extremely steep, grass-covered terrain Old-snow problem on shady slopes. Glide-snow avalanches on sunny slopes. Avalanche danger is MODERATE. A slab can be triggered even by minimum additional loading in extremely steep terrain, more often by large additional loading. Most avalanche prone locations occur on N/E facing slopes and in wind-loaded gullies above 2000 m Up to 2300 m in extremely steep grass-covered terrain, glide-snow avalanches can trigger. Melt-freeze crusts dominate, many surfaces are utterly windblown, gullies are filled with drifts. On sunny slopes, some transformation to firn is possible, The snowdrifts from the early part of the week have not bonded with the old snowpack well. Inside the old snow are persistent weak layers which, however, are now well-blanketed over. Good visibility, quite sunny. Intermittently dense high-altitude cloudbanks will pass through. Little wind. At 2000 m: +1 degree. On the weekend, slight daytime danger cycle. Conditions like in springtime.
