Avalanche Summary

A few small loose wet avalanches have been observed in recent days and will likely continue during periods of sun.

Snowpack Summary

Dry, settled powder may still be found on high north-facing slopes, while elsewhere, a daily melt-freeze cycle is creating a hard crust overnight that softens during the day.

An old persistent weak layer may still be present 100 to 150 cm below the surface on high north-facing slopes, but it is rounding and unreactive under current conditions.

Treeline elevations still hold over 200 cm of snow, but coverage is rapidly thinning at lower elevations.

Terrain and Travel Advice

  • Limit exposure to steep, sun exposed slopes, especially when the solar radiation is strong.
  • Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
