Snowpack Summary
Sun exposed slopes in the alpine and all aspects at treeline and below have become moist to wet during the heat of the day. In these areas, spring conditions are in effect; the avalanche hazard will fluctuate greatly depending on the strength of the overnight freeze and how quickly the snowpack is warmed up each day. Dry snow may still be found on north-facing slopes in the alpine. At these locations, 30-50 cm of well settled snow overlies a layer of facets (sugary snow) that was buried around March 10th.
Problems
Wind Slabs
Up to 10 cm snow is forecasted to accumulate by the end of Thursday along with westerly winds gusting to 45 km/h. Expect thin wind slab development at ridgetop and lee terrain.
Be cautious of sluffing in steep terrain.Be careful with wind loaded pockets, especially near ridge crests and roll-overs.Use extra caution on slopes if the snow is moist or wet.
