Hohgant

Moderate avalanche danger will be encountered over a wide area.

Snowpack

The fresh fallen snow of the last few days has been transported by the northerly winds. The snowdrift accumulations which were generated below approximately 2800 m lie deposited atop a rain crust which is frequently quite smooth in many areas. Beneath these snowdrift accumulations the old snowpack is quite favourably layered, following the recently descending temperatures. Marked weak layers more deeply embedded inside the snow cover have not been discovered to date.

Weather forecast through Thursday, 23.11.2023

It is expected to be sunny and become increasingly mild during the course of the day. The zero-degree level will ascend to 3800 m.

• northern flank of the Alps: 10 to 20 cm, as much as 30 cm from place to place in the central sector of the northern flank of the Alps;
• in the other regions of Switzerland less, in the southern regions it remained dry.

Temperature

At midday at 2000 m, between -3 °C in the northern regions and 0 °C in the southern regions.

Outlook through Saturday, 25.11.2023

As a consequence of strong to storm-strength northwesterly winds, skies are expected to be heavily overcast. On Friday morning precipitation will set in from the northeast which will spread out starting on Friday evening and subsequently intensify in the northern and the eastern regions. The snowfall level is expected to swiftly descend from 1200 m down to the lowlands on Friday evening. By Saturday afternoon, on the northern Alpine Ridge from the Wildstrubel as far as Liechtenstein and in northern Grisons, 30 to 50 cm of fresh snowfall is anticipated, more from place to place. In the remaining regions of Switzerland, 10 to 20 cm of fresh snow is anticipated over widespread areas. In the furthermost southern regions it is expected to be sunny and dry on both days as a consequence of northerly foehn winds. Avalanche danger levels in the northeastern regions are expected to increase slightly as soon as Friday during the course of the day. On Saturday, avalanche danger will increase in all regions of Switzerland except in the south. Significant increases in the danger levels are expected in the major areas of precipitation.
