The alpine rating is , the treeline rating is , and the below treeline rating is Known problems include Wind Slabs, Loose Wet and Cornices.
Timothy Johnson,
Strong winds have created fresh wind slabs in the alpine. On Wednesday watch out if the sun comes out - wet loose avalanche down low and cornices up high could wake up.
Summary
Weather Forecast
Wednesday
A mix of sun and cloud.
Precipitation: Nil.
Alpine temperature: High -8 C.
Ridge wind west: 10-25 km/h.
Freezing level: 1400 metres.
Thursday
A mix of sun and cloud.
Precipitation: Nil.
Alpine temperature: Low -8 C, High -3 C.
Ridge wind southwest: 15 km/h.
Freezing level: 2000 metres.
Snowpack Summary
Strong SW winds are redistributing the recent snow into lee features in the alpine and down into treeline. The freezing level is around 2200m. There is a sun crust high into the alpine on solar aspects and and melt freeze crust up to 2200m. There is a well settled mid-pack.
Avalanche Summary
A few small, size 1 wind slabs have been observed in higher elevation leeward features.
Confidence
Timing or intensity of solar radiation is uncertain on Tuesday
Problems
Wind Slabs
Strong SW winds created fresh wind slabs. These new wind slabs sit over a variety of firm surfaces including wind effected snow and sun/temperature crusts.
- Use caution in lee areas. Recent wind loading has created wind slabs.
- Watch for stiffer feeling snow. Avoid areas that appear wind loaded.
Aspects: North, North East, East, South East, North West.
Elevations: Alpine, Treeline.
Likelihood
Expected Size
Loose Wet
Main concern during the heat of the day and solar input.
- Minimize exposure to steep, sun exposed slopes when the solar radiation is strong.
- Avoid sun exposed slopes when the solar radiation is strong, especially if snow is moist or wet.
Aspects: South East, South, South West, West.
Elevations: Below Treeline.
Likelihood
Expected Size
Cornices
Fresh cornices might become reactive with strong solar input
- Cornices become weak with daytime heating, so travel early on exposed slopes.
Aspects: North, North East, East, North West.
Elevations: Alpine.
