Regions: South Coast.

Look for signs of a warming snowpack, the likelihood of loose wet avalanches will increase with rising temperatures, especially in areas where fresh snow has accumulated.

Weather Forecast

SUNDAY NIGHT: Mostly cloudy / west wind, up to 20 km/h / treeline temperature +2 C / freezing level 1400 mMONDAY: Mix of sun and cloud / south wind, up to 25 km/h / treeline temperature +4 C / freezing level 1600 mTUESDAY: Cloudy with sunny breaks / southwest wind, 10-25 km/h / treeline temperature +3 C / freezing level 1700 mWEDNESDAY: Flurries, 15-20 cm accumulation / southwest wind, 20 gusting to 40 km/h / treeline temperature -4 C / freezing level 1400 m

Avalanche Summary

No new avalanches have been reported in the region. The likelihood of loose wet avalanches on sun-affected slopes will increase throughout the day as temperatures rise and the snowpack warms, especially in areas where fresh snow has accumulated.

Snowpack Summary

Precipitation amounts totaled 80 to 100 mm over the weekend. This has likely fallen as snow above around 1700 m and as rain below 1200 m, where the snowpack is rapidly melting. Between 1200 m and 1700 m, expect a rapid change from 0 cm to 80 cm of recent snowfall. The snow has likely been blown around by strong south wind.

Avalanche Problems

Loose Wet

The recent snow will moisten quickly on southerly aspects when the clouds clear. 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

Wind Slabs

Substantial snowfall has accumulated around treeline and above, and fell with strong southwest wind. Expect to find the deepest and most reactive deposits in lee terrain features.

Be careful with wind-loaded pockets, especially near ridge crests and roll-overs.Minimize exposure to overhead avalanche terrain, as large avalanches may travel far.Travel conservatively above the recent rain-snow line (around 1300 m).

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

Elevations: Alpine.

Likelihood: Possible

Expected Size: 1 - 1.5
