South Coast Inland

Wind slabs may remain reactive to riders at upper elevations. Expect deteriorating visibility in the afternoon as the next storm blows in.

Moderate

• We have a good understanding of the snowpack structure and confidence in the weather forecast.

On Thursday and Friday, several rider-triggered storm and wind slabs were reported on north to east aspects at treeline throughout the region. Evidence of natural wind slabs up to size 2 were observed in the alpine in the Duffy area in this MIN report.

Evidence of persistent slab avalanches up to size 2.5 running on the February crust during the storm cycle last week was observed in the South Chilcotin area in the northeast of the region.

New snow dusts extensively wind-affected surfaces at upper elevations and possibly sun crust on steep solar aspects.

Below 2300 m, a widespread crust formed in early March is buried 20 to 60 cm deep.

Another crust, formed in February, is buried roughly 60 to 100 cm deep, surrounded by weak faceted grains. Activity on this layer has been isolated to the northeast of the region, in the South Chilcotins.

The remainder of the snowpack is generally strong and well-bonded.

• Be alert to changing conditions throughout the day.
• Be careful as you transition into wind-affected terrain.
• Keep your guard up as storm slabs may remain sensitive to human triggering.
• Use extra caution around cornices: they are large, fragile, and can trigger slabs on slopes below.
