    Probabilidad
    Unlikely - Possible

    The presence of wind slab is isolated to the north of the region where more snow fall and stronger winds occurred.
  • Loose Wet

    Probabilidad
    Likely
    Tamaño
    1–1.5
    The sun will affect the new snow and increase the potential for triggering loose wet avalanches.

Confidence

Moderate - Timing or intensity of solar radiation is uncertain

Avalanche Summary

In the far north of the region on Friday, Saturday, Monday and Tuesday loose wet avalanche activity up to size 2 was reported on solar aspects. Sporadic natural slab avalanches were also reported in the alpine and treeline, but no activity was reported from north aspects.

Snowpack Summary

Up to 10 cm of new snow at upper elevations from Monday night sits on a variety of surfaces. On higher north aspects above 2000 m it may sit on some dry, faceted snow and/or isolated old wind slabs. At most other places the new snow is sitting on either moist snow or a crust. There are still a handful of melt/freeze crusts, surface hoar and facets in the upper snowpack, but all of these layers appear to have gone dormant for the time being. The snowpack at mid and upper elevations is gaining strength in consecutive nights with below freezing temperatures.
