Fresh storm snow sits on a reactive and widespread layer of surface hoar.
Be cautious around roll-overs, especially in wind-loaded areas.
Recent storm snow is forming a slab over large surface hoar crystals. This could result in storm slabs that remain reactive longer than usual and could propagate further. Surface hoar is more likely to be well preserved at treeline.
Evidence of a natural avalanche cycle (up to size 2.5) from the recent storm was reported in the Hudson Bay Range. On Wednesday, debris of wet loose, wind and storm slab avalanches were observed depending on aspects and elevations.
If you do go into the backcountry, consider submitting a Mountain Information Network report.
30 to 60 cm of recent snow sits above a large layer of surface hoar. This layer likely exists on all aspects above 1200 m. Below this elevation a crust exists on all aspects.
In general, the snowpack is still shallow for this time of year with snowpack depths at treeline ranging from 50 to 150 cm. Early season hazards are still a concern.
