While wind loaded pockets remain the #1 concern, pay close attention the effects to the strong spring sun. Plan on avoiding steep solar terrain this afternoon.
Weather Forecast
Sunny this morning with convective clouds building this afternoon. Flurries later in the day with trace accumulation. Alpine temperature near -6.0 with freezing levels rising to 1300m. Ridge winds will be north, 10-20km/hr. Expect a similar weather pattern tomorrow. A pacific system arrives on Monday with 25cm by late Tuesday and warmer temps.
Snowpack Summary
An overnight refreeze has prompted a return of winter conditions below treeline. Approximately 20cm of new snow in the past 48hrs has softened up the skiing at all elevations. Wind slabs linger above treeline and are reactive to skiers. Watch for a buried crust on steep solar aspects and isolated patches of surface hoar, both down 20-40cm.
Avalanche Summary
Natural avalanche activity tapered off after the wind triggered cycle of yesterday morning. A group reported a skier controlled a sz 1 wind slab avalanche on a convexity above treeline in the Aulkan drainage. Isolated loose wet solar triggered avalanches were observed in the highway corridor west of Rogers Pass.
Confidence
Freezing levels are uncertain
Problems
Wind Slabs
Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
