Watch for active wind transport of snow, fresh wind slabs are expected to be reactive to rider triggers.

Monitor changing conditions as you gain elevation and shift aspect.

Moderate

• We are uncertain due to a limited number of field observations.

No new avalanches have been reported. However, observations are currently limited.

By Monday afternoon up to 25 cm of new snow may have fallen over wind affected surfaces at upper elevations from recent southwest winds. Rising temperatures and rain will affect the recent snow to around 1800 m.

A persistent weak layer sits below, present as crust and facets at treeline and above, and a combination of crust and surface hoar in sheltered features and lower elevations.

The mid/lower snowpack is generally well settled and strong.

Snowpack depth ranges between 100 to 250 cm at treeline elevations.

• A moist or wet snow surface, pinwheeling, and natural avalanches are all indicators of a weakening snowpack.
• Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
