Lo esencial

Areas of unstable wet snow may form today on steep, sun exposed slopes as daytime warming progresses. Exercise caution in steep sun exposed terrain where the surface crust has melted away and the top few inches of snow are wet. Consider opting to lower angle slopes or more shaded aspects if unstable wet snow is present.

    Daytime warming is expected to lead to the development of wet loose avalanche conditions as the day progresses. SE-S-SW aspect terrain near exposed rock and cliff bands will warm first, with slower warming in other sun exposed areas. Most of the wet loose avalanche activity today is expected at size D1 and only involve the top few inches of the snowpack. Avalanches up to size D2 could occur on long open slopes with sustained slope angles. On these longer slopes, more of the recent storm snow could become entrained, increasing the size of the debris pile.

    Once the surface crust melts away, wet loose avalanches are possible in the area. Roller balls and pinwheels are often indicators that wet loose avalanches could occur. If signs of unstable wet snow are present, consider moving to less steep terrain or changing locations to a more shaded aspect.

    Easy to initiate pinwheels and wet loose sluffs on SE aspect test slopes, indicating the possibility of wet loose avalanches on larger slopes. Castle Peak, Donner Summit area, CA
