Storm slabs are expected to remain reactive to human triggers, especially in wind loaded features
Watch for clearing skies; even brief periods of sun may trigger natural avalanches.
Storm slabs will be most reactive where they overly a smooth crust. Sun may moisten the snow surface and trigger slabs naturally.
The last avalanche activity reported was on Tuesday, where a size 2 naturally triggered wet loose avalanche was reported from a northeast alpine face.
Looking forward, we expect new slabs to be reactive to human triggers.
Storm snow totals reach 30 cm in areas around Pine Pass, overlying dry snow on high north-facing slopes and over a crust elsewhere. The upper snowpack is generally moist, with a crust from last week's rain event.
Below treeline elevations hold isothermal snow.
A persistent weak layer from early March is buried 50–100 cm deep, as surface hoar on sheltered north and east alpine slopes. No recent avalanches have been reported, it remains a concern for triggering under heavy loads or as a potential step-down layer.
