Large storm slabs will likely be reactive to human triggers on Wednesday.
Choose simple, low angle terrain, and avoid overhead hazards.
Persistent weak layers of crusts/facets and/or surface hoar in the top 150 cm of the snowpack remain a concern in this region, especially where there is not a thick crust under the recent snow.
70 to 90 cm of recent snow and strong southwest winds have formed reactive storm slabs overlying a weak layer of surface hoar and/or facets.
On Monday, numerous natural and skier triggered storm slabs up to size 2 were reported near Terrace on all elevations/aspects. Several were remotely triggered by skiers. Average crown depths were 30 to 40 cm.
Numerous naturally triggered wet loose avalanches up to size 2 were also reported below treeline.
70 to 90 cm of recent snow and strong southwest winds have formed reactive storm slabs overlying a weak layer of surface hoar and/or facets. This weak layer will make large storm slabs more likely to trigger.
There are multiple persistent weak layers consisting of crust/facets or surface hoar in the top 150 cm of the snowpack.
The lower snowpack is generally well settled and strong.
