Regions

Coquihalla, Harrison-Fraser, Manning.

Use simple terrain and conservative decision-making.

New snow and wind will form reactive storm slabs.

Confidence

Moderate

Avalanche Summary

Looking ahead, we expect new and reactive storm slabs to form, and natural avalanches could also occur.

No new avalanches have been reported in the region, but reports in this region have been limited.

If you go into the backcountry, consider sharing your observations to the MIN.

Snowpack Summary

Up to 25 cm of new snow will be redistributed by strong to extreme southwesterly winds. Expect to find deeper and more reactive deposits on north and east-facing slopes. This falls on 30 to 50 cm of recent snow. Below this, there are hard wind-affected surfaces or a thin melt-freeze crust on southerly slopes.

A supportive crust is found 60 to 80 cm deep on all aspects except on high, north-facing alpine terrain, and the recent settling snow is bonding well to it.

A weak layer of facets and surface hoar from February is now 90 to 150 cm deep and a layer of facets and surface hoar from late January is 130 to 190 cm deep. No recent notable test results have been seen on these layers.

Weather Summary

Saturday Night

Cloudy with 5 cm of snow. 35 to 50 km/h southwest ridgetop winds. Treeline temperature -5 °C.

Sunday

Cloudy with 15 to 20 cm of snow. 40 to 75 km/h southwest ridgetop winds. Treeline temperature rising to 0 °C. Freezing level rises to 1500 m by 4 pm.

Monday

In the overnight period, 20 to 30 mm is expected, falling as snow above 1500 m.

Cloudy with 10 to 15 mm, falling as snow above 1500 m. 50 to 80 km/h southwest ridgetop winds. Treeline temperature 4 °C.

Tuesday

Cloudy with 2 mm, falling as snow above 2000 m. 20 to 50 km/h southwest ridgetop winds. Treeline temperature 6 °C.

Terrain and Travel Advice

  • Use conservative route selection. Choose simple, low angle terrain with no overhead hazard.
  • Sheltered slopes at lower elevations will offer the safest conditions.
  • Use extra caution for areas that are experiencing rapidly warming temperatures for the first time.

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.
