Regions: South Coast.

Flurries will accumulate through the day. Use caution around ridge crests and lee terrain features, where the most reactive deposits will form.

Confidence

Moderate - Intensity of incoming weather systems is uncertain

Weather Forecast

TUESDAY NIGHT: Mostly cloudy / west-northwest wind, 10 gusting to 40 km/h / treeline temperature 0 C / freezing level 1100 mWEDNESDAY: Snow, 5-15 cm accumulation / southwest wind, 20 gusting to 45 km/h / treeline temperature +1 C / freezing level 1300 mTHURSDAY: Cloudy with isolated wet flurries, 5-10 cm / north wind, 10-30 km/h / treeline temperature +3 C / freezing level 1500 m FRIDAY: Mix of sun and cloud / south wind 10-30 km/h / treeline temperature +3 C / freezing level 1700 m

Avalanche Summary

No new avalanches have been reported in the region. 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, especially in areas with fresh snow.

Snowpack Summary

Flurries have fallen over high alpine terrain, wetter precipitation at lower elevations is keeping the snowpack moist and encouraging rapid melt below 1200 m.

Avalanche Problems

Storm Slabs

Flurries are expected to start early Wednesday morning. Avalanche hazard will rise as snowfall accumulates and gains cohesion.

Be careful with wind loaded pockets, especially near ridge crests and roll-overs.Minimize overhead exposure during periods of heavy loading from new snow and wind.Pay attention to overhead hazards like cornices.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 1.5

Loose Wet

The snowpack will moisten quickly as temperatures rise. Loose wet avalanches can grow in danger quickly, so use added caution when the sun is out.

Use extra caution on slopes if the snow is moist or wet.Minimize exposure to steep, sun-exposed slopes when the solar radiation is strong.

Aspects: East, South East, South, South West, West.

Elevations: All elevations.

Likelihood: Possible

Expected Size: 1 - 1.5
