Watch for newly formed, reactive wind slabs as you transition into wind-affected terrain.

The snowpack is shallow and generally weak with many hazards on or near the surface.

Avalanche Summary

No new avalanches have been reported. There are very few field observations coming from this forecast area. Remember that a lack of avalanche reports does not necessarily mean a lack of avalanche activity.

If you go out in the backcountry, please consider sharing your observations on the Mountain Information Network (MIN).

Snowpack Summary

Check out this MIN report from Core Lodge.

The snowpack is shallow, faceted and highly wind-affected. Expect scouring on windward slopes and isolated pockets of deep wind slab over facets near ridge crests on leeward slopes. A crust has formed on the surface below treeline.

Several crusts exist in the mid pack. Isolated pockets of buried surface hoar could be found in sheltered terrain.

Average snowpack depths at treeline are highly variable (20 to 70 cm). Many hazards are on or just below the surface.

Weather Summary

Monday Night

A mix of sun and cloud, no new snow. Southwest alpine wind 60 to 100 km/h. Treeline temperature 0 °C. Freezing level rises to 3000 m.

Tuesday

Mostly cloudy with snowfall, up to 5 cm of accumulation. Southwest alpine wind 50 to 100 km/h. Freezing level 1000 m dropping to valley bottom.

Wednesday

A mix of sun and cloud, no new snow. Southwest alpine wind 20 to 50 km/h. Treeline temperature -1 °C.

Thursday

A mix of sun and cloud, no new snow. Southwest alpine wind 50 to 80 km /h. Treeline temperature 0 °C.

Terrain and Travel Advice

  • Avoid steep, rocky, and wind effected areas where triggering slabs is more likely.
  • Expect shallow snow cover that barely covers ground roughness.
  • Avalanche danger is often elevated in alpine gullies where snow has accumulated.

Avalanche Problems

Wind Slabs

New snow, wind, and warming may form fresh wind slab sitting over a weak faceted base.
