Avalanche Forecast

Mar 4th, 2024–Mar 5th, 2024
Alpine
4: High
The avalanche danger rating in the alpine will be high
Treeline
4: High
The avalanche danger rating at treeline will be high
Below Treeline
3: Considerable
The avalanche danger rating below treeline will be considerable
Alpine
3: Considerable
The avalanche danger rating in the alpine will be considerable
Treeline
3: Considerable
The avalanche danger rating at treeline will be considerable
Below Treeline
2: Moderate
The avalanche danger rating below treeline will be moderate
Alpine
3: Considerable
The avalanche danger rating in the alpine will be considerable
Treeline
3: Considerable
The avalanche danger rating at treeline will be considerable
Below Treeline
2: Moderate
The avalanche danger rating below treeline will be moderate

Regions: Birkenhead, Duffey, South Chilcotin, South Coast Inland, Stein, Taseko.

Danger may reach HIGH on sun affected slopes. Sun can rapidly increase avalanche danger and may produce natural avalanche activity.

Stick to low-angle and supported terrain features

Confidence

Moderate

Avalanche Summary

Remotely triggered and natural avalanches continue to be reported to size 2. These avalanches continue to occur on the buried weak layers around 80 cm deep.

A notable size 3 slab avalanche was observed to have failed near the ground, around 2 m deep on a north facing slope.

Snowpack Summary

Recent storm snow is beginning to settle. However, reports show this storm snow is still not bonding well to the crust/facet/surface hoar layer buried 50-90 cm deep. This layer continues to show sensitivity to human triggers, and will take time to begin to settle and bond.

Strong sunshine is expected to create moist or wet snow on south facing slopes and increase the reactivity of weak layers.

Weather Summary

Monday Night

Partly cloudy. 10-20 km/hr westerly winds. Freezing levels at valley bottom.

Tuesday

Mostly clear skies. 10-20 km/hr westerly winds. Treeline temperature -10 °C. Freezing levels at valley bottom.

Wednesday

Mostly clear skies. 10-20 km/hr northwest winds. Treeline temperature -8 °C. Freezing levels around 500 m.

Thursday

Mostly clear skies. 10-20 km/hr northwest winds. Treeline temperature -4 °C. Freezing levels head towards 1000 m.

Terrain and Travel Advice

  • Minimize exposure to sun-exposed slopes when the solar radiation is strong.
  • Keep in mind that human triggering potential persists as natural avalanching tapers off.
  • Fresh snow rests on a problematic persistent slab, don't let good riding lure you into complacency.

Avalanche Problems

Persistent Slabs

Buried weak layers are most concerning at treeline elevations. Small avalanches may step down to this layer resulting in very large, destructive avalanches.

Use low-angle, simple terrain to help manage this problem.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Likely

Expected Size: 1.5 - 3

Wind Slabs

Larger and more reactive slabs sit on north and east facing slopes near ridges.

Aspects: North, North East, East, West, North West.

Elevations: Alpine, Treeline.

Likelihood: Likely

Expected Size: 1 - 2.5
