Avalanche Summary

No recent avalanches observed.

Snowpack Summary

Snow depths are around 40 to 60 cm at treeline and alpine elevations, although there may be deeper deposits in wind-loaded areas. Approximately 20 cm new snow sits above a layer of surface hoar (north aspects) or a thin crust (south aspects). All but the highest and/or smoothest slopes have insufficient snow cover for avalanches to occur at this time.

Problems

Wind Slabs

An icon showing Wind Slabs
Pockets of wind-loaded snow could exist in exposed areas behind ridges and peaks.
Be careful with wind loaded pockets, especially near ridge crests and roll-overs.Use caution above cliffs and terrain traps where small avalanches may have severe consequences.

Aspects: North, North East, East, South East, North West.

Elevations: Alpine.
