Kernpunkte

Uncertainty is high. Few natural avalanches have been observed but a significant slab avalanche that stepped down to ground was accidentally released by a skier near Shangri-la on Thursday.

Lawinenprobleme

  • Wind Slabs

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit
    Possible
    Größe
    1–2
    Wind slabs in immediate lee areas have the potential to step down and create large full depth avalanches.

  • Persistent Slabs

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit
    Possible
    Größe
    1–3
    This avalanche condition is quite uncertain and large slopes should be treated with caution. Especially those with recent wind loading or those that face the sun.

    Two avalanches were triggered by the sun today.

Weather Forecast

Light  snow and cool temperatures are expected for the weekend.  Temperatures are expected to climb next week.

Snowpack Summary

Total storm snow over the Mar 15 interface is approx. 40 cm but quite variable. Open areas in the southern forecast area are showing more surface wind effect. The Mar 15 interface is weak made up of facets over variable surfaces depending on aspect and exposure. Little slab development has been observed to date.

Avalanche Summary

Two size 1.5 to 2 avalanches were observed on steep south facing slopes today.  One skier accidental size 2.5 slab was reported from Thursday afternoon in the Shangri-La area. 

Confidence

Timing or intensity of solar radiation is uncertain
