Approximately 15-30 cm of new snow accumulated over the past week at upper elevations. This storm snow 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 temperatures have been promoting isothermal snowpack conditions and melting the snowpack away.
Recent snow and moderate to strong winds have likely built recent wind slabs in the lee of terrain features. More recent slabs and slabs formed on steeper slopes may remain reactive to human triggers on Thursday.
- 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, South East.
