DANGER RATINGS (Make sure you understand the danger level meanings)
 
Outlook Friday Saturday Sunday 
Alpine MODERATE MODERATE MODERATE
Treeline LOW LOW LOW
Below Tree line LOW LOW LOW

Confidence: Good

Main Concerns: (Avalanche problems) 

Loose Dry-  10 to 15 cm of low density new snow is bonding poorly to old crust creating conditions for loose dry avalanches at treeline and Alpine on steeper terrain. These would be small in many areas but are running fast and far on old crust surface. In the Alpine these could be large on specific steep terrain with long run outs.

Wind Slab- The concern for older wind slabs up to 80cm remains at the highest of treeline and Alpine terrain in lees to southerly winds. These could be large in isolated areas of wind loaded terrain that were sensitive to triggers and have not settled at treeline. In the Alpine these specific areas could produce large avalanches.

Travel/Terrain Advice: Be aware of terrain hazards and the consequences of a long fast ride in loose snow on a well established crust. Remain suspect of deeper slabs in previously wind loaded terrain at the highest of treeline and all Alpine terrain. Remain alert when entering lee aspects and seek alternatives when visibility is obscured.

Past Weather: Cool and clear conditions have created surface hoar on all aspects and elevations. Cool temperatures continued to preserve the low density snow in shaded aspects Treeline and above.

Avalanche Summary:  Numerous loose dry running fast and far up to size 1 observed on steep treeline terrain.

Snowpack Description: 

Surface- Surface hoar developing on all surfaces .

Upper- A 15cm melt freeze crust bridges the upper snowpack,below this a variety of new snow layers exist and depending on elevation and wind effect. Many of these older layers contained buried surface hoar creating weaknesses. Sensitive wind slabs and storm slabs of 80cm or greater exist in isolated treeline and specific Alpine terrain.

Mid- Well settled.

Lower-Well settled and old rain crust(deeply buried) in some locations south(not reactive)

Weather Forecast:

Friday -    up to 2cm precipitation. Winds W to 20kmh.     Freezing level 600m

Saturday- up to 5cm precipitation. Winds NW to 23kmh.  Freezing level 800m.

Sunday-  up to 5cm new snow .    Winds NE to 37kmh.   Freezing level to 600m.

Outlook Wednesday Thursday Friday 
Alpine CONSIDERABLE CONSIDERABLE CONSIDERABLE
Treeline MODERATE MODERATE MODERATE
Below Tree line LOW LOW LOW

Confidence: Fair, lack of Alpine observations.

Main Concerns: (Avalanche problems) 

Loose Dry- Up to 18cm new snow bonding poorly to old crust has created conditions for loose dry avalanches at treeline and Alpine on steeper terrain. These would be small in many areas but are running fast and far on old crust surface. In the Alpine these could be large on specific steep terrain with long run outs.

Wind Slab- The concern for older wind slabs up to 80cm remains at the highest of treeline and Alpine terrain in lees to southerly winds. These could be large in isolated areas of wind loaded terrain that were sensitive to triggers and have not settled at treeline. In the Alpine these specific areas could produce large avalanches.

Travel/Terrain Advice: Be aware of the consequences of a long fast ride in loose snow on crusts. Remain suspect of deeper slabs in previously wind loaded terrain at the highest of treeline and all Alpine terrain.

Past Weather: Normal freezing levels (below 1000m) has allowed the saturated and warm snowpack to crust up and stiffen. New snow Sunday has accumulated up to 18cm. Cool temperatures have preserved the low density snow in shaded aspects Treeline and above.

Avalanche Summary: Loose dry running fast and far up to size 1 observed on steep treeline terrain.

Snowpack Description: 

Surface- New low density snow up to 18cm. Old rain saturated crust with no boot penetration.

Upper- A variety of new snow layers exist in the upper snowpack depending on elevation and wind effect. Many of these older layers contained buried surface hoar creating weaknesses. Sensitive wind slabs and storm slabs of 80cm or greater exist in isolated treeline and specific Alpine terrain.

Mid- Well settled.

Lower-Well settled and old rain crust(deeply buried) in some locations south(not reactive)

Weather Forecast:

Monday - up to 4cm precipitation. Winds NW to 20kmh.  Freezing level 1000m .  

Tuesday-  up to 5cm precipitation. Winds NW to 49kmh.  Freezing level 800m.

Wednesday- Trace-9cm new snow .  Winds NW to 42kmh. Freezing level to 700m.

Travel/Terrain Advice: Be aware of the consequences of a long fast ride in loose snow on crusts. Remain suspect of wind loaded terrain at the highest of treeline and Alpine terrain.

Past Weather: Normal freezing levels (below 1000m) has allowed the saturated and warm snowpack to crust up and stiffen. New snow Sunday has accumulated up to 10cm.

Important Notice

This bulletin covers the mountainous region of Vancouver Island from the Mt. Cain Ski Area in the North to the Beaufort range to the South including the mountains of Strathcona Provincial Park.

This is a regional forecast and significant variation may exist within the forecast area. The information and danger ratings are intended as a trip planning aid for recreational, backcountry users of avalanche terrain; they are not meant to be used as the sole factor in determining the avalanche danger presented by a specific slope.

Always include local weather, snowpack and avalanche observations in your decision to travel in avalanche terrain. Observations and experience may lead to different conclusions from what is reported or recommended. See disclaimer for further details. The technical data used to produce these bulletins is obtained from a variety of sources, including local ski areas and remote weather resources.
