Surface softening will be minimal with wind increasing and the FAFL dropping.

High winds and slick surfaces will be the biggest hazard in steep terrain today.

    Unlikely to be significant accumulation with minimal snow available for transport and very high winds.

    Avoid any obvious new loading or hollow feeling snow.

Recent Avalanche Activity

No recent activity has been reported.

Current Snowpack Conditions

A generally consolidated snowpack within the region.

Variety of surface conditions exist - Melt Freeze Crust on sunny slopes except for low angle areas. On shady slopes the snow surface is effected by the recent wind but staying cold.

Some Surface Hoar has been observed in sheltered areas but is unlikely to survive the increasing winds.

Mountain Weather

NW winds increasing to Gale force in the afternoon. High cloud developing and the FAFL dropping to 1300.

Sliding Danger

There is a slick layer in areas exposed to the wind and under thin layers of snow.

This will get worse today with the wind scouring. Ice axe and crampons are key for moving into steep/extreme terrain.

Expect to encounter it near ridge top and turn around early if so.

Forecast Confidence

High

  • We are confident the likelihood of avalanches will increase with the forecast weather.
  • We are uncertain due to the variability of wind effect on the snowpack.
