Regions

Lizard-Flathead.

Despite a decent overnight refreeze, solars aspects slopes will soften quickly with intense sunshine and warming temperatures. Be particularly cautious on and under steep slopes when they are baking in the sun.

Confidence

High - We have a good understanding of the snowpack structure and confidence in the weather forecast

Weather Forecast

A ridge of high pressure will build in for Tuesday, bringing a sunny and dry day with freezing levels up to 2000 to 2500 metres. 

MONDAY NIGHT: Cloudy with clear periods and isolated flurries. Trace of precipitation. 20-30 km/h westerly winds becoming northeasterly. Low alpine temperature -5 C with freezing level at valley bottom.

TUESDAY: Sunny. No precipitation. 15-30 km/h northeasterly winds. High alpine temperature +2 C with freezing level around 2200 m.

WEDNESDAY: A mix of sun and cloud with isolated flurries. 1-3 cm. 20-40 km/h southwesterly winds. High alpine temperature 0 C with freezing level around 1800 m.

THURSDAY: A mix of sun and cloud with isolated flurries. Trace of precipitation. 15-20 km/h westerly winds. High alpine temperature -2 C with freezing level around 1700 m.

Avalanche Summary

On Sunday, a few natural wet loose avalanches size 1 were observed on steep slopes. Also, a large slab avalanche triggered by a cornice fall in the last few days have been reported.

Snowpack Summary

The upper snowpack is going through a diurnal melt freeze cycle. Refrozen crust on all aspects up to 2000 m and on solar aspects in the alpine. Surfaces are softening in the afternoon at all elevations, and on steep, sunny slopes. Recent warm temperatures, sun, and rain have made the top 10-30 cm of the snowpack moist. At very low elevations, the snowpack may be wet and isothermal, depending on overnight freezing levels. 

The mid and lower snowpack are generally strong and well bonded.

Terrain and Travel

  • Be alert to conditions that change with elevation and sun exposure.
  • When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
  • As surface loses cohesion due to melting, loose wet avalanches become common in steeper terrain.
  • Minimize exposure to sun-exposed slopes when the solar radiation is strong.

Problems

Loose Wet

Loose Wet avalanches are the release of wet unconsolidated snow or slush. These avalanches typically occur within layers of wet snow near the surface of the snowpack, but they may quickly gouge into lower snowpack layers. Like Loose Dry Avalanches, they start at a point and entrain snow as they move downhill, forming a fan-shaped avalanche. Other names for loose-wet avalanches include point-release avalanches or sluffs. Loose Wet avalanches can trigger slab avalanches that break into deeper snow layers.
