    This layer is becoming less reactive. However, be observant of lee areas and how the layer may react at a local level.

  • Persistent Slabs

    Snowpack tests on this layer today produced easy results. Despite the easy results no avalanche activity was noted. This is a layer to approach cautiously over the next few days.

Weather Forecast

A very slight warming trend is expected to affect the forecast region starting tomorrow, however, it is not expected to be warm enough to affect the hazard rating significantly. Otherwise little change is expected.

Snowpack Summary

30-40cm of snow sit on top of Feb10th layer of facets, sun crust and surface hoar. Field tests continue to show an easy to moderate sudden collapse at this interface. Some isolated wind slabs are present in the alpine. If triggered these wind slabs could step down to the Feb 10th interface.

Avalanche Summary

Evidence of a major cycle (occurring 72 hours ago) is still visible throughout the forecast region. However, no new avalanches were observed of reported today.

Confidence

The weather pattern is stable
