Avalanche Forecast
Regions: Haines Pass.
Avoid steep wind-loaded features, rider-triggered avalanches remain likely in leeward terrain.
Confidence
Low
Avalanche Summary
Field observations have been non-existent in the last week due to periodic closures of the Haines road.
If you make it into the backcountry, please submit your observations to the Mountain Information Network.
Snowpack Summary
Expect 30 to 40 cm of soft snow on the surface in areas sheltered from the wind. Moderate to strong easterly and southerly wind has likely formed deeper, more reactive deposits in leeward terrain. The recent snow covers old, firm, wind-affected or wind-scoured surfaces.
The midpack is generally strong and bridges the weak crystals at the base of the snowpack.

Terrain and Travel Advice
- Be especially cautious as you transition into wind affected terrain.
- Avoid freshly wind loaded features, especially near ridge crests, roll-overs and in steep terrain.
Avalanche Problems
Wind Slabs
Avoid freshly wind-loaded slopes. While the likelihood of naturally triggered avalanches has diminished, but we expect wind slabs to remain reactive to human triggering for several more days.
Aspects: North, North East, South West, West, North West.
Elevations: Alpine, Treeline.
Likelihood: Possible - Likely
Expected Size: 1 - 2.5
