Regions

Waterton Lakes, Waterton.

These storms are coming in warm... and then cooling off. Wet-loose could be a problem at lower elevations Tuesday through Wednesday. While the alpine and tree line will see continued wind slab formation throughout the forecast period.

Confidence

Moderate

  • We are uncertain due to the timing, track, and intensity of the incoming weather system.

Avalanche Summary

Several wind slab and dry loose avalanches, up to size 1.5, observed in the alpine.

Snowpack Summary

The upcoming storm snow will be falling on top of 5-10 cm of snow from Saturday. These layers are being redistributed by moderate to strong winds. A widespread rain crust sits below. Under the crust is moist snow that is slowly refreezing.

Weather Summary

Tues

Wet flurries. Up to 4 cm of snow. Alpine Low of 0 2 °C, High of 2 °C. SW wind gusting to 65 km/h. Freezing level at 2500 m.

Wed

Isolated flurries. Alpine Low of -4 °C, High of 2 °C. SW wind gusting to 80 km/h. Freezing level at 2000 m.

Thurs

Flurries, with up to 11 cm of snow. Alpine Low of -7 °C, High of -5 °C. SW wind gusting to 45 km/h. Freezing level at valley bottom.

Terrain and Travel Advice

  • Be careful as you transition into wind-affected terrain.
  • Use extra caution for areas that are experiencing rapidly warming temperatures for the first time.
  • Be careful with wind-loaded pockets, especially near ridge crests and rollovers.

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.

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.
