Lo esencial

Moderate still means human-triggered avalanches possible. Approach any consequential slope with the appropriate caution.

Problemas de aludes

  • Wind Slabs

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Unlikely - Possible
    Tamaño
    1–2
    Windslabs appear to be bonding well, however caution is still warranted in immediate lees and cross loaded terrain above treeline.

  • Persistent Slabs

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Possible
    Tamaño
    1–3
    Persistent weak layers of decomposed surface hoar, facets, and depth hoar can be found in many locations. Although these layers have been dormant lately, careful slope evaluation is essential. Be cautious of shallow areas with slab over facets.

Weather Forecast

Steady cooling trend to continue into the week. Only trace amounts of snow expected for the foreseeable future. Overnight lows of -10 to -13C. Light to moderate Southwest winds.

Snowpack Summary

Moderate SW winds have built wind slab at tree-line and above. These slabs may be up to 40cm thick. The mid-pack consists of buried wind and persistent slab with a failure plane down 60cm that is producing mostly resistant planar results in tests. In the valley bottom the snowpack is weak and unconsolidated making for tough trail breaking.

Avalanche Summary

No new avalanches observed today.
