An incoming storm heightens avalanche hazard over the next few days. Give the storm slab some time to settle.

Summary

Confidence

Moderate

Avalanche Summary

Expect new snow to be easily triggered in steep terrain.

Few dry loose and wet loose small avalanches have been reported early in the week. These have been both sun and rider triggered in steep terrain.

Field teams have observed rider triggered size 1's the past few days, which were isolated to the top 10-15cm of snow on old firm bed surfaces. Despite their small size, they were moving fast in steep terrain.

Snowpack Summary

New snow on Thursday (Jan 30th) covered widespread surface hoar and sun crusts on steep solar aspects.

Below this interface are firm, wind pressed surfaces in exposed areas and low density sugary snow in sheltered areas.

The Jan 7th layer is down 30-60cm, comprised of surface hoar (all aspects) and/or a thin crust on steep S aspects. The mid and lower snowpack are well bonded and strong.

Weather Summary

Moderate to heavy precipitation through to Saturday.

Tonight 6cm. Alp Low: -9°C. Ridge wind SW 25 km/h. Freezing level (FZL) at valley bottom

Fri 10cm. Alp high -7°C. Ridge wind SW 30km/h. FLZ 1000m.

Sat 7cm. Alp low -15°C. Ridge wind W 15km/h gusting to 50km/h. FZL 1000m.

Sun Trace precip. Alp low -22°C. Ridge wind SE 30km/hr, FZL 1000m

Saturday

Terrain and Travel Advice

  • Storm slabs in motion may step down to deeper layers resulting in large avalanches.
  • Be careful with sluffing in steep terrain, especially above cliffs and terrain traps.

Problems

Storm Slabs

An icon showing Storm Slabs

New snow is accumulating on top of a widespread layer of surface hoar at all elevations. This new snow will be accompanied by moderate wind transport increasing the likelihood of natural and rider triggered avalanches.

Aspects: All aspects.

Elevations: All elevations.

Likelihood

Likely

Expected Size

1 - 2

Persistent Slabs

An icon showing Persistent Slabs

Although unlikely, natural activity during the storm has the potential to step down to deeper layers in the snowpack.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood

Unlikely

Expected Size

1 - 3
