Lizard-Flathead, Flathead, Lizard.

Keep your head up and assess conditions as you move through terrain

Avalanche danger could increase throughout the day with the arrival of precipitation

Confidence

Moderate

Avalanche Summary

A large glide slab released naturally on Monday. These natural hazards should be given a wide berth.

Wet and dry loose avalanches continue to be triggered by skiers in the region. These avalanches have occurred in steep terrain on a variety of aspects and elevations.

Snowpack Summary

The upper  snowpack is variable. A crust exists on or near the surface on all aspects below treeline and on all sun exposed slopes.  On high north aspects, Up to 30 cm of snow has buried a thick melt-freeze crust from late March. Below these crusts, the upper snowpack is moist.

The base of the snowpack is generally well settled.

Weather Summary

Precipitation amounts over the next 24hrs could be highly variable due to convection.

Tuesday Night

Mostly cloudy with 0 to 5 cm of snow. 20 to 40 km/h west ridgetop wind. Treeline temperature -3 °C.

Wednesday

Cloudy with 5 to 15 mm of mixed precipitation in the afternoon. 20 to 40 km/h southwest ridgetop wind. Freezing level rising to 1800 m.

Thursday

Mostly cloudy with up to 10 cm of snow. 20 to 50 km/h north ridgetop wind. Treeline temperature -6 °C.

Friday

Sunny. 10 to 20 km/h northwest ridgetop wind . Treeline temperature -3 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Be careful as you transition into wind-affected terrain.
  • Make observations and continually assess conditions as you travel.
  • Back off slopes as the surface becomes moist or wet with rising temperatures.

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.
