Lo esencial

The upper snowpack has been saturated and weakened by recent rain. Avoid high-consequence avalanche terrain.

    Warm temperatures and rain may reawaken various weak layers deep within the snowpack.

    The upper snowpack is moist and continues to loss strength with above-freezing temperatures.

    Rainfall has added a significant load to the upper snowpack. This is of particular concern in areas where a heavy, wet slab has formed over an old crust.

Confidence

Moderate

Avalanche Summary

Widespread natural, loose wet avalanche activity was reported on Sunday at all elevations, up to size 1.5. One natural, size 3, wet slab avalanche was reported on Sunday in alpine terrain.

Two separate natural avalanches were observed on Sunday failing on layers deep within the snowpack. They both occurred in north-facing alpine terrain. One was a size 2.5, while the other was a size 3.

Snowpack Summary

Rainfall has saturated the upper snowpack at all elevations.

The mid and lower snowpack consists of various crusts and layers of facets or surface hoar. These layers deeper in the snowpack are more concerning with the warm temperatures and increased load from rain.

Tuesday

Cloudy with no precipitation, south alpine winds 20 to 50 km/h, freezing levels around 2200 m.

Wednesday

Terrain and Travel Advice

  • Back off slopes as the surface becomes moist or wet with rising temperatures.
  • Avoid areas with overhead hazard.
  • Avoid steep convex slopes.
  • Closely monitor how the new snow is bonding to the old surface.
