That layer is still a player! Conservative trip plans are the best way to manage the combination of a persistent avalanche problem and extreme cold weather. Read more about these tricky moderate conditions in this forecaster blog.
Variable winds may carry loose snow and build wind slabs in exposed and open features. Use caution around ridges, cornices, and loaded features. In steeper terrain, be cautious of dry-loose avalanches and mindful of sluffing.
This layer is STILL a player. Each day there is a steady trickle of rider triggered avalanches on this layer. Small terrain features are producing small avalanche results, bigger features could ruin your day. 40-65 cm snow sits above a buried weak layer of surface hoar, facets, and a crust (depending on elevation and aspect). Reports suggest it is touchiest on northerly and easterly aspects, but don't let your guard down elsewhere.
THURSDAY NIGHT - Mostly clear / light to moderate north east wind / alpine low temperature near -28
FRIDAY - Cold, a few clouds / light north east wind / alpine high temperature near -18
SATURDAY - Increasing cloud / light to moderate north east wind / alpine high temperature near -20
SUNDAY - Overcast / light southerly wind/ highs near -15
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
On Tuesday there were a couple of smaller skier triggered avalanches, but of note was a remote triggered size 2 on Mt. Fernie (suspected surface hoar). Also on Tuesday, explosive control yielded wind slab avalanche results up to size 2.
February has been a busy one for avalanche activity with human triggered avalanches going back over a week that are too numerous to list. Do some research and check out the MIN reports in our region, 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 it is touchiest 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.
