Glacier.

Warm temps & rising freezing levels will increase the likelihood human triggered activity.

Beware of early season hazards at tree-line & below.

Avalanche Summary

No new avalanches observed over the weekend.

Late last week an avalanche cycle triggered by wind and rain peaked on Thursday night. Several avalanches up to size 3.0 were observed in the highway corridor, some running well into the bare ground on lower elevation fans.

Snowpack Summary

Last week's storm brought approximately 45cm of new snow to the Alpine. Below 2200m this precip fell as rain and saturated the snowpack. The storm also brought strong-extreme Southwest winds which redistributed snow in the Alpine. There may be a lingering layer of buried surface hoar in the alpine. This could be up to 80cm deep.

Weather Summary

Warm temperatures and high freezing levels are the dominant factor in the weather

Tonight: Cloudy with wet flurries, Alpine temperature: Low 0°C , Wind: West 15km/hr, Freezing Level: 2200m

Mon: Mainly cloudy. Temp: High +1 . FZL 2300m. Light South wind.

Tues: Flurries, 8cms. Low -4 °C, High -1 °C. FZL 2000m. Light Southwest wind.

Weds: Cloudy with flurries. Alpine Low -7°C & High -2°C. FZL 1600m. Wind: SW 20km/hr.

Terrain and Travel Advice

  • Snow is accumulating at higher elevations, despite lower elevations being almost snow-free.

Problems

Wind Slabs

Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.

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.
