Watch for signs of instability as warm temperatures and continued snowfall will create storm slabs.
Weak layers deeper in the snowpack may become more reactive as temperatures rise.
60-90 cm of snow sits above a crust and surface hoar which has produced natural, remote and rider-triggered avalanches in the past week.
New snow and warm temperatures are building storm slabs that may be thicker and more reactive in wind affected areas.
Over the weekend, numerous rider triggered wind slabs and storm slabs (size 1 and 2) were reported on many aspects at all elevations.
Around the Sicamous area, natural and remote triggered avalanches were reported up to size 2, and were likely triggerd by warm temperatures.
On Friday, explosive avalanche control generally produced size 1 to 2 wind slabs, with one step down avalanche that was size 2.5 on a north aspect at treeline.
30 to 50 cm of recent snow from the last two storms is settling fast with warm temperatures. This snow has buried a variety of snow surfaces including unconsolidated faceted snow, surface hoar and firm wind-pressed snow in open terrain at treeline and above.
Down 60 to 80 cm, a crust, facet and or surface hoar layer exists.
130+ cm down another surface hoar layer exists that was buried in early December. This layer is of most concern above 2000 m where a robust crust doesn't exist above it.
