Limit exposure to cornices. Cornice falls can trigger large avalanches on the slopes below. The likelihood of natural cornice falls could increase with solar input and warming.
Keep an eye on the weather. New snow and wind will likely form storm and wind slabs throughout the day.

new storm and wind slabs will likely form throughout the day. Size and likelihood of triggering these slabs will be greatest near ridge crests and steep roll overs.
Tuesday night: Stormy with up to 5cm of new snow and moderate to strong south winds. Low of -1 at 900 m.
Wednesday: Stormy with 5 to 10 cm of new snow expected. Moderate southwest winds. Freezing level around 1100 m.
Thursday: cloudy with flurries bringing up to 5 cm of snow with light southerly winds. Freezing level around 1100 m.
Friday: stormy with 10 to 15 cm of new snow expected. Light to moderate southeast winds and freezing levels around 1100 m.
OnMonday two large natural cornice falls were observed in the north of the region. They triggered wind slabs on the slope below. A few natural wind slab avalanches were also observed in this part of the region.
Two large natural icefalls were observed at Bear Pass.
In the Terrace area wet loose avalanches up to size two were observed on all aspects and elevations except high north.
New storm and wind slabs will likely form throughout the day. A crust can be found at or near the surface on all aspects and elevations except high north terrain. Moist snow will likely be observed at lower elevations and could result in wet loose avalanches.
A weak layer of surface hoar from mid March buried 70-120 cm deep can still be found but is considered dormant in the Terrace area. In the far north of the region it continues to produce large avalanches.
