An incoming storm will bring bring new snow and wind to the alpine. Expect to find a storm slab building (especially in lee features!) over the next couple of days.
New snow and strong gusty winds will create a fresh storm slab problem. This will build throughout the day Tuesday and will be most reactive in lee features.
Wet loose avalanches will remain possible during the heat of the day or during times of strong sun affect. Heavy wet snow on the move can easily push you off line or off balance, be aware of this while traveling above terrain traps.
Several wet loose avalanches up to size 2.5 and a size 3 glide slab release have been observed through the highway corridor over the weekend. Neighboring operations have reported natural cornice failures.
We are transitioning to a spring snowpack. Surface conditions vary from crust to moist or wet snow depending on time of day, aspect and elevation.
A thick rain crust from the March atmospheric river sits 20-50cm below the surface.
Below treeline the surface varies from isothermal sticky snow to refrozen tree bombs and huge debris fields from the massive avalanche cycle in March.
A low pressure system will move through the region bringing snow and increased winds.
