Level 1, low

Avalanches can in isolated cases be released especially on little-used, rather lightly snow-covered north facing slopes. These avalanche prone locations are to be found especially in extremely steep terrain above approximately 2200 m. Avalanches can in very isolated cases reach medium size. Extremely steep slopes are to be traversed by snow sport participants one at a time.
In addition small wind slabs will form adjacent to ridgelines and in pass areas and at elevated altitudes. Apart from the danger of being buried, restraint should be exercised as well in view of the danger of avalanches sweeping people along and giving rise to falls.

Level 2, moderate

Wind slabs

Avalanche prone locations
In particular in west to north to east facing aspects above approximately 2200m.

In particular in west to north to east facing aspects above approximately 2200m.

Danger description

As a consequence of fresh snow and a strong northerly wind, wind slabs will form. These are mostly small but can in some cases be released easily. Avalanche prone locations are to be found in particular in gullies and bowls, and behind abrupt changes in the terrain and in pass areas in all aspects. The wind slabs are to be assessed with care and prudence. Apart from the danger of being buried, restraint should be exercised as well in view of the danger of avalanches sweeping people along and giving rise to falls.
Avalanches can additionally be released in deeper layers in particular in areas where the snow cover is rather shallow. These avalanche prone locations are rare. They are to be found in particular on extremely steep north facing slopes above approximately 2200 m. Avalanches can in very isolated cases reach medium size. Extremely steep slopes are to be traversed by snow sport participants one at a time.

Level 1, low

Isolated avalanche prone locations are to be found in particular in extremely steep terrain at elevated altitudes. Restraint should be exercised because avalanches can sweep people along and give rise to falls.

Edition: 25.3.2019, 17:00 / Next update: 26.3.2019, 18:00
Snowpack
The bonding of the snowpack is favourable over a wide area. In particular where the snow cover is shallow on very steep north facing slopes above approximately 2200 m, weak layers exist in the snowpack in some places. In isolated cases, avalanches up to medium size can be triggered in these layers. The near-surface layers are loosely bonded in some instances on north facing slopes. These layers, together with a little fresh snow in some regions, will be transported by the strong to storm force northerly wind. The fresh snow drift accumulations are prone to triggering in some instances.
Underneath the crust the snowpack is moist all the way through up to 3000 m on south facing slopes, and up to approximately 2000 m on east and west facing slopes. In view of the cool weather, hardly any further wet snow avalanches or gliding avalanches are likely to occur.
Observed weather on Monday, 25.03.2019
During the second half of Sunday night, cloud built up in the north. During the day on the northern flank of the Alps and in northern Grisons it was mostly very cloudy with a little precipitation in some regions. The snowfall level was approximately 1200 m. Otherwise the weather was partly sunny, but mostly sunny in the far south.
Fresh snow
In the eastern part of the northern flank of the Alps and in northern Grisons: a few centimetres
Temperature
At midday at 2000 m: between -2 °C in the north and +3 °C in the south
Wind
In the night already and during the day, slightly freshening wind from the west and north
  • In particular in the eastern regions and on the southern flank of the Alps, mostly moderate, but also strong in the afternoon
  • Otherwise mostly light
Weather forecast through Tuesday, 26.03.2019
After a cloudy night in the north, the day will remain mostly cloudy at first with a little precipitation in the east in particular. It will then become increasingly sunny from the west. The south will be sunny with a northerly wind.
Fresh snow
Until the precipitation ceases on Tuesday morning, the following amounts of snow will fall down to low altitudes:
  • Northern Alpine ridge: 5 to 15 cm; larger quantities may fall in showers in some localities
  • Elsewhere: smaller amounts
  • Southern flank of the Alps: remaining mostly dry
Temperature
At midday at 2000 m: between -7 °C in the north and -4 °C in the south
Wind
From the north to northeast
  • At elevated altitudes and on the southern flank of the Alps, strong, occasionally storm force
  • Otherwise light to moderate
Outlook through Thursday, 28.03.2019
On Wednesday in the east, extensive cloudbanks will linger in some instances. Otherwise and on Thursday it will be mostly sunny. At elevated altitudes the wind will not ease significantly until Thursday. The danger of dry avalanches will not change significantly. The danger of both wet snow and gliding avalanches will increase a little during each of the two days.
 

Your observations can improve the quality of the avalanche bulletin. We are very grateful for any reports and photos received.

Please report your observations of avalanches or alarm signs, or your estimation of the avalanche danger, or simply send us a picture illustrating the current situation. Your report from the field will be considered along with all the other information when we assess the avalanche danger. It is impossible, however, to reflect the exact content of each individual report in the avalanche bulletin.

The best way to file a report is by completing the interactive form on this page. If your report is to be used in the 5 pm avalanche bulletin, it should be submitted before 2:30 pm if possible. Reports received later will normally be given consideration in the next assessment.

No avalanche bulletins are being published at the moment. Nevertheless, you should still stay up to date with the avalanche situation in the mountains, especially if there is fresh snow.

However, the SLF will, by way of exception, also issue avalanche bulletins in the summer in case of heavy snowfall. There are different ways you can be notified when these bulletins based on the snow situation are published:

  • by push alert on SLF's free White Risk mobile app: appearing in four languages (English, German, French and Italian), this can be downloaded from iTunes App Store (for iPhones) or Google Play Store (for Android);
  • by mobile text message (SMS): please send an SMS with the message START SLF SOMMER to the phone number 9234 – you can cancel this service at any time by sending an SMS with the message STOP SLF SOMMER; cost: CHF 0.20 per SMS;
  • via an RSS feed which informs you whenever an avalanche bulletin is published.

Depending on the snow and avalanche situation, the regular publication of avalanche bulletin recommences in November/December.
