Avalanche Summary
There have been no recent reports of avalanche activity. If you're out we'd love it if you would submit what you're seeing to the Mountain Information Network.
Snowpack Summary
Expect to see 5-10 cm of new snow at upper elevations Monday morning on top of the 15-30 cm of new snow accumulated over the past week. 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
Recent new snow and moderate to strong winds have likely built fresh wind slabs in the lee of terrain features.
- Be cautious as you transition into wind affected terrain.
- Be careful with wind loaded pockets, especially near ridge crests and roll-overs.
Aspects: North, North East, East, North West.
Elevations: Alpine, Treeline.
