Avalanche Forecast

SUNDAY NIGHT - Partly cloudy / trace of new snow possible / light south west wind with potential for some localized moderate wind / low near -19

MONDAY - Overcast / 1-5 cm / light westerly wind / high near -12

TUESDAY - Increasing cloud / light west wind / high near -12

WEDNESDAY - Afternoon clearing possible / light westerly wind / highs near -8

On Sunday a ski cut triggered a size 1.5 on an open feature at the treeline/alpine interface in the Lizard Range. This failed on the late January persistent surface hoar layer.

Despite the the lack of snow, there has been in increase in activity on the persistent weak layer. On Thursday and Friday there were human and remote triggered avalanches up to size 2 reported. Locations like Mount Fernie, 2000, Liverwurst and McDermid were a few location examples. Some of the avalanches were remote triggered from a distance away. Some folks submitted MINs, you can read them here.

On Wednesday there was a size 1.5 skier triggered avalanche that failed on the late January surface hoar/facet layer. It was on a south east facing slope in the Tunnel Creek area. See MIN

February has been a busy one for avalanche activity with human triggered avalanches going back well over a week that are too numerous to list. Do some research and check out the MIN reports in our region when planning your trip, click here.

Recent northerly and shifting winds have reverse loaded features; slabs may be found in open terrain on a variety of aspects. Surface faceting and surface hoar growth is occurring with clear nights and frigid temperatures.

A persistent weak layer lurks 30-70 cm below the surface. In some places it consists of surface hoar, in other places just facets, or crust/facet combinations. This weak interface has been responsible for the majority of recent avalanches. Reports suggest the surface hoar interface at treeline is the biggest repeat offender, and things have been most reactive on northerly and easterly aspects, but don't let your guard down elsewhere.

Below 1600 m a hard melt-freeze crust is underneath 20-40 cm recent snow. A solid mid-pack sits above a deeply buried crust and facet layers near the bottom of the snowpack (150-200 cm deep), which is currently unreactive. 

• Carefully assess open slopes and convex rolls where buried surface hoar may be preserved.
• Avoid terrain traps such as gullies and cliffs where the consequence of any avalanche could be serious.
• Watch for signs of instability like whumpfing, hollow sounds, shooting cracks or recent avalanches.
• Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
