Choose conservative, low consequence terrain.
Buried weak layers remain rider triggerable.
Recent southerly winds have likely formed wind slabs near ridge crests. If triggered wind slabs could step down to a deeper layer.
A weak layer of facets and surface hoar buried last week may still be rider triggerable.
Wet loose avalanches could occur on steep sun exposed slopes. These avalanches could step down to a deep layer.
Many natural and rider-triggered avalanches released on Thursday on the weak layers described in the Snowpack Summary (see photos below). These weak layers may take some time to strengthen, meaning they will likely remain active to human traffic for the foreseeable future.
Please consider sharing your observations to the Mountain Information Network.
Recent storm snow has been redistributed by southerly winds and has likely formed wind slabs near ridge crest. As the winds switch direction wind effect could be found on all aspects.
The snow surface on sun exposed slopes will likely become moist during the day.
Weak layers of surface hoar crystals and/or faceted grains may be found around 30 to 70 cm deep. This layer has produced recent avalanche activity and is unstable in snowpack tests.
Cornices are large and looming at this time of year.
