Avalanche Summary
No recent avalanches have been reported.
Snowpack Summary
Wind slabs and cornices are likely to have developed on a fairly widespread basis and may be found in unusual locations lee to NE and E outflow winds. Spotty surface hoar was buried in the upper snowpack in sheltered treeline areas, although little is known about its reactivity. Near the base of the snowpack, a facet/crust layer remains a concern for unlikely but possible deep releases. It may be possible to trigger this weakness with a very heavy load (e.g. cornice fall) or from a thin-spot trigger point.
