North of a line from the Rhone to the Rhine and in the extreme west of Lower Valais, weak layers in the snowpack are mostly thickly covered and are now hardly triggerable by human activity.

South of a line from the Rhône to the Rhine, the persistent weak layers that have been a feature since the beginning of January are still present. However, the number of avalanche-prone locations has decreased significantly. Reports of avalanches and alarm signs indicate that the situation in Grisons remains the most precarious.

Weak layers in the lower part of the snowpack are being weakened as they become moistened for the first time. Wet slab avalanches are possible as the day progresses. These can occur naturally but can also be triggered by winter sport participants, at present mainly on sunny slopes below approximately 2600 m.

After a clear night, conditions were sunny and mild.

Fresh snow

-

Temperature

At midday at 2000 m, between +4 °C in the northwest and 0 °C in the southeast.

Wind

• Sometimes moderate from westerly directions during the night
• Otherwise light

After a clear night, conditions will be sunny and, in the north with a foehn wind tendency, very mild.

Fresh snow

-

Temperature

At midday at 2000 m, around +5 °C in the north and -1 °C in the south

Wind

• Moderate southerly wind in northern regions exposed to the foehn wind
• Otherwise light

There will be clear spells during the nights with fairly sunny conditions during the days. Temperatures will remain mild, with zero-degree levels between 2600 m in the north and 2200 m in the south. Winds will be light.

The danger of dry avalanches will continue to decrease, but only slowly in Grisons due to the weak snowpack structure. The danger of wet avalanches will increase over the course of each day, but somewhat earlier than on previous days due to slightly reduced outgoing longwave radiation during the night.
