Snowpack Summary

15-30 cm of new snow accumulated over the past week at upper elevations. This all likely sits over a widespread, supportive melt-freeze crust from early April. Surface hoar and facets were previously observed on this crust on high north aspects. At lower elevations, ongoing warm weather has been promoting isothermal snowpack conditions and melting the snowpack away.

Problems

Wind Slabs

An icon showing Wind Slabs

Recent new snow and moderate to strong winds have likely built fresh wind slabs in the lee of terrain features.

  • Be careful with wind loaded pockets, especially near ridge crests and roll-overs.
  • Be cautious as you transition into wind affected terrain.

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

Elevations: Alpine.
