Confidence

Moderate - Due to the number of field observations

Weather Forecast

We'll see little change in the weather pattern: valley cloud and cool temperatures down low but sunny and warm up high. MONDAY: Sunny with cloudy periods. Light wind. Freezing level near 1700m with an above freezing layer around 3000 m. Alpine high temperatures near +3.TUESDAY: Sunny with increasing cloud in the afternoon. Light to moderate west wind. Freezing level near 2000 m with a colder air layer in the valleys. WEDNESDAY: Sunny with cloudy periods. Light northerly winds. Freezing level near 1700 m.

Avalanche Summary

Over the past few days there have been small wet loose avalanches reported on steep south (west) aspects above 2400m elevation. A previous wind slab cycle has slowed down over the last few days.

Snowpack Summary

On steep sunny slopes, warm temperatures up high will melt and weaken upper snowpack layers. Warming also has the potential to wake up more deeply buried crust layers. Recently formed wind slabs are gaining strength, but may still be found in the lee of ridges and terrain breaks primarily on north through south east aspects. Below tree line, the snowpack is shallow--look out for early season hazards like open creeks and tree stumps.

Avalanche Problems

Loose Wet

Loose wet avalanches are possible in steep, rocky, sunny terrain. Warming could also wake up more deeply buried weak layers.
Use caution above ledges and cliffs where small avalanches may have severe consequences.Minimize exposure to steep, sun exposed slopes when the solar radiation is strong.

Aspects: North, North East, East, South East.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 2
