Avalanche Summary

Snowpack Summary

A dusting of new snow now covers a fairly widespread surface hoar layer. Below this 5-15 cm of dry faceted snow may sit on a variety of old surfaces including a melt-freeze crust on solar aspects in the alpine, wind affected snow in exposed terrain, and surface hoar in sheltered areas at treeline and lower elevations. Overall, the snowpack is still quite shallow and weak throughout the region.

Problems

Wind Slabs

An icon showing Wind Slabs
Fresh wind slabs may be sensitive to rider triggering in steep and unsupported lee and cross-loaded terrain.  If we receive more than 20cm of new snow we could see more widespread reactive storm slabs developing.
Be careful with wind loaded pockets, especially near ridge crests and roll-overs.>Avoid open slopes and convex rolls at and below treeline where buried surface hoar may be preserved.>
