Lo esencial

In the spring, convective flurries can drop vastly different amounts of snow from valley to valley. Maintain situational awareness and change your plans if faced with unexpected weather.

Problemas de aludes

  • Wind Slabs

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Possible - Likely
    Tamaño
    1–2

    Moderate to strong south west winds and new snow from convective activity will make new wind slabs.

  • Loose Wet

    Tamaño
    1–2

    Warming temperatures will continue to produce wet loose avalanches.

  • Deep Persistent Slabs

    The bottom of the snowpack is inherently weak with well-developed Facets and Depth Hoar. The next few days could see this problem moving into the reactive category with dramatically rising freezing levels.

Avalanche Summary

No new avalanches observed

Post avalanche observations to the MIN.

Snowpack Summary

Sun crusts on solar aspects into the alpine and a melt-freeze crust at tree line and below on all aspects. Small wind slabs in the alpine from moderate to strong SW winds and recent new snow. A layer of sun crust or facets linger in the mid-pack. The main concern is the depth hoar and basal facets at the bottom causing our deep persistent slab problem.

Terrain and Travel Advice

  • In areas where deep persistent slabs may exist, avoid shallow or variable depth snowpacks and unsupported terrain features.
