Avalanche Problems

Storm Slabs

Windslabs of 40cms or thicker may be found on north and east facing terrain, and other lee features which may be crossloaded by the continuing westerly winds. Very warm temperatures Tuesday helped settle in these slabs, but triggering is possible.

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

Elevations: All elevations.

Likelihood: Possible

Expected Size: 1 - 2

Wet Slabs

Some weather forecasts are predicting a very warm Wednesday, with freezing levels rising to 2000m or higher. Warm and sunny southerly aspects may develop daytime surface instabilities resulting in moist loose or slab avalanches during the day.

Aspects: North, North East, East.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 2
