Regions: Lizard-Flathead.

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

Confidence

Moderate - Intensity of incoming weather systems is uncertain

Avalanche Summary

There have been no recent avalanche observations in the forecast region.If the sun comes out for prolonged periods of time, the chances of loose avalanches will increase, especially in areas with fresh snow.

Snowpack Summary

The snowpack on sun exposed slopes in the alpine and all aspects at treeline and is moist or wet during the heat of the day, especially under direct sun. 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.

Avalanche Problems

Loose Wet

The likelihood of loose wet avalanches will increase through the day if temperatures rise, especially in areas with fresh snow.
Use extra caution on slopes if the snow is moist or wet.Avoid exposure to terrain traps where the consequences of a small avalanche could be serious.Be cautious of sluffing in steep terrain.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Possible

Expected Size: 1 - 1.5
