Avalanche Forecast
Regions: Northwest Inland.
Field observations from the Northwest Inland are scarce. Use this forecast as a starting point for assessing the distribution and reactivity of recent wind slabs.
Confidence
Low - Due to the number of field observations

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
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 weather has been promoting isothermal snowpack conditions and melting the snowpack away.
Avalanche Problems
Wind Slabs
Recent snow and moderate to strong winds have likely built recent wind slabs in the lee of terrain features. These may remain reactive to human triggers on Wednesday.
- 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.
