In sintesi

Minimize exposure to steep slopes as temperatures warm through the day, especially in areas with fresh snow.

    The likelihood of loose wet avalanches will increase as through the day as temperatures rise, especially in areas where new snow accumulates.

Avalanche Summary

If the sun comes out for prolonged periods of time, the chances of loose avalanches will increase, especially in areas with fresh snow.Last Wednesday, there were reports of a few size 1 loose wet avalanches in the Fernie area.

Snowpack Summary

The snowpack on sun exposed slopes in the alpine and all aspects at treeline and below may become moist or wet during the heat of the day, especially if the sun comes out. With spring conditions, the avalanche hazard will fluctuate greatly depending on the strength of the overnight freeze and how quickly the snowpack is warmed up each day.Steep, north facing alpine terrain, still holds a cold, dry snowpack where well settled slab sits over weak facets (sugary snow). Human triggering of persistent slabs on this layer may still be possible; especially in rocky alpine terrain with a shallow or highly variable depth snowpack.
