Regions

Lizard-Flathead, South Rockies, Akamina, Flathead, Lizard, Bull, Crowsnest North, Crowsnest South, Elkford East, Elkford West.

Use caution at higher elevations where recent snow may have formed reactive storm and wind slabs.

The upper snowpack can weaken rapidly during periods of direct sun exposure.

Confidence

Low

  • We are uncertain about forecast snowfall amounts.
  • We are uncertain about how quickly the snowpack will recover and gain strength.
  • We are uncertain due to a limited number of field observations.

Avalanche Summary

No new avalanche activity has been reported since Monday, when warm temperatures and sun triggered wet loose avalanches.

Snowpack Summary

Varying amounts of snow continue to fall at higher elevations, particularly on the east side of the region. Recent snow sits atop variable melt-freeze crusts or moist snow.

While weak, faceted layers may exist in the mid and lower snowpack (especially in shallow snowpack areas), these layers are not expected to be reactive while the upper snowpack remains strong and supportive. This could change later in the spring during prolonged periods of above-freezing temperatures.

Check out this MIN report from Thursday from the Crowsnest area for more details.

Sunday
Mostly cloudy. Trace amounts of snow at treeline. 20 km/h south ridgetop wind. Treeline temperature -8 °C.

Monday

Terrain and Travel Advice

  • Limit exposure to steep, sun exposed slopes, especially when the solar radiation is strong.
  • Keep your guard up as storm slabs may remain sensitive to human triggering.
  • Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
  • Investigate the bond of the recent snow before committing to your line.

Problems

Storm Slabs

Storm Slab avalanches are the release of a cohesive layer (a slab) of new snow that breaks within new snow or on the old snow surface. Storm-slabs typically last between a few hours and few days (following snowfall). Storm-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.
