Avalanche prone locations for dry-snow avalanches occur above 2000 m, mostly in seldom-tracked steep terrain. Transitions from shallow to deep snow, e.g. entries into gullies and bowls, require caution. Avalanches are possible particularly by large additional loading. Small fresh snowdrift accumulations in high-altitude exposed spots should be circumvented. A cautious route selection is recommended. Due to solar radiation and daytime warming, small to medium sized wet-snow and glide-snow avalanches are possible during the course of the day.

In the upper and mid-parts of the snowpack are expansively metamorphosed (faceted) layers, mostly blanketed to a sufficient degree, thus unlikely to trigger. If at all, then in transitions from shallow to deep snow. These danger zones are not visible to the naked eye. In higher exposed ones there are small, older snowdrift accumulations. Due to solar radiation and daytime warming the snowpack often forfeits firmness during the day.

Nocturnal hours: mostly dry, only variably cloudy skies. Monday: frequent sunshine but for a few harmless cirrus clouds. Rising temperatures: at 2000 m from -3 to +4 degrees. The brisk northerly winds will slacken off.

Tuesday will be very sunny and mild. Danger of wet-snow avalanches will increase during the daytime, especially on sunny slopes.
