Spring is a dynamic time of year where conditions can vary widely and change rapidly. Localized convective snowfall can appear out of nowhere and even short periods of strong sun can rapidly destabilize the upper snowpack.
Carefully assess your local conditions and pay attention to how the weather is affecting the snowpack throughout the day.
Summary
Confidence
Avalanche Summary
Recent avalanche activity has been limited to small (size 1) loose dry avalanches out of steep northerly aspects on the weekend.
Snowpack Summary
A moist or crusty surface has formed on southerly aspects treeline and below. 10 to 30 cm of recent snow sits over moist or crusty surfaces in most areas except for shaded terrain above 1600 m. The new snow is expected to bond well to the old layers, but could potentially be poor where dry snow sits over a hard crust. The middle and lower snowpack are strong and well-bonded.

Terrain and Travel Advice
- Remember that in the spring strong solar radiation and warm temperatures can weaken the snow in a matter of minutes.
- Watch for wind-loaded pockets especially around ridgecrest and in extreme terrain.
- Carefully monitor the bond between the new snow and old surface.
Problems
Wind Slabs
Recent snow may remain triggerable in wind loaded terrain features at upper elevations. Wind slabs may be poorly bonded to an underlying crust.
