dsaly, Avalanche Canada

South Coast.

Wet flurries on Wednesday added to a moist, spring snowpack. Fresh snow, and showers or rising temperatures during the day can quickly increase the likelihood of loose wet avalanches.

Summary

Confidence

Moderate - Timing, track, or intensity of incoming weather system is uncertain

Weather Forecast

WEDNESDAY NIGHT: Isolated wet flurries, up to 15 cm accumulation / southwest wind, 20 gusting to 45 km/h / treeline temperature 0 C / freezing level 1000 mTHURSDAY: Showers and wet flurries, 10 cm snow at upper elevations / south wind, 15-30 km/h / treeline temperature +3 C / freezing level 1500 m FRIDAY: Mix of sun and cloud / south wind, 10-25 km/h / treeline temperature +3 C / freezing level 1500 mSATURDAY: Snow and rain, 20-30 cm / south wind, 20-45 km/h / treeline temperature +3 C / freezing level 1400 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

Around 15 cm snow and rain fell through Wednesday at upper elevations. Warm temperatures and wet precipitation are producing a moist, spring snowpack. Below 1200 m, the snowpack is rapidly disappearing. 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.

Problems

Loose Wet

Wet flurries, rain and rising temperatures can all warm the snowpack and increase the likelihood for loose wet avalanches, especially in areas with fresh snow.

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

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

Elevations: All elevations.

Likelihood

Possible

Expected Size

1 - 1.5

Storm Slabs

Snowfall Wednesday accumulated at upper elevations. Use caution around ridge crests and lee terrain features, where deposits will be most reactive.

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

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood

Possible

Expected Size

1 - 1.5
