Avalanche Forecast

Moderate

On Friday a size 3 avalanche occurred in Haines Pass, running over the highway.

A few size 1.5 wind slab avalanches were reported by the Field Team in the Nadahini area on Thursday, failing below corniced ridgeline features. Skiers were able to trigger wind slab deposits on north- and east-facing slopes near Haines Junction.

If you go into the backcountry, please submit your observations to the Mountain Information Network.

Moderate and strong south winds have redistributed 30 cm of new snow. Deeper, more reactive deposits exist in leeward terrain. Many windward features are stripped back to the ground.

A weak layer of faceted crystals or surface hoar found 50 to 80 cm deep remains a concern. A crust exists buried 100 cm deep. The midpack is generally facetted to the ground.

With warm temperatures on Saturday, a surface crust may have formed at the surface at lower elevations, up to 1500 m.

• Seek out wind sheltered terrain below treeline where you can avoid wind slabs and find great riding.
• Carefully evaluate steep lines for wind slabs.
• Back off if you encounter whumpfing, hollow sounds, or shooting cracks.
