Regions

Banff Yoho Kootenay, Little Yoho, Banff, East Side 93N, Kootenay, Lake Louise, LLSA, Sunshine, West Side 93N, Field.

Expect a good freeze Friday morning. A warming trend with increasing solar input will follow over the next few days—start and finish early. Hazard will be LOW in the AM, and may increase in the PM.

Confidence

Moderate

  • We are uncertain about how the timing or intensity of solar radiation will affect the snowpack.

Avalanche Summary

On a flight to Yoho today, the only fresh (within 48 hours) avalanche was a size 2, likely triggered by a cornice. This type of avalanche may be an issue when things really warm up. Otherwise, temperatures stayed pretty cool, and no other avalanches were reported or observed.

Snowpack Summary

Sun crusts on solar aspects extend to ridgeline. Shady aspects hold dry, settled snow above 2300 m. Temperature crusts are forming below 2300 m, with isothermal snow at lower elevations. The January 24 persistent weak layer (facets over crust) is down 70–160+ cm and has been unreactive this week. Below this, the snowpack is generally strong with no significant weaknesses.

Weather Summary

Thursday: Expect a decent freeze in the AM, then freezing levels will rise to 2100m. Light NW winds, and no snow.

Friday: Expect a decent freeze, then freezing levels rising to 2600m with strong solar input, light W winds., and no snow.

Saturday: Mainly cloudy with freezing levels rising to 2800m, light SW winds and no snow.

Terrain and Travel Advice

  • Start your day early and be out of avalanche terrain during the heat of the day.
  • Travel early on sun-exposed slopes before cornices weaken with daytime warming.

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.
