In sintesi

New snow and strong winds = reactive storm slabs that require a cautious approach to backcountry travel. Stick to lower-angled, low consequence terrain to manage it.

    Recent storm snow and moderate to strong winds have formed storm slabs that will be reactive to human triggers on Saturday. Danger will be greatest in open, higher elevation terrain.

Confidence

Moderate

  • Uncertainty is due to the limited number of field observations.

Avalanche Summary

Reports have been limited. Natural and human triggered avalanche activity has been observed near Cypress.

Tricky avalanche conditions are likely to persist through Saturday as the new snow takes time to settle.

Snowpack Summary

Up to 40 cm of new snow brings us to roughly 120 to 170 cm of settling storm snow since Dec 17.

Each round of substantial snowfall and wind loading has produced storm and wind slab problems, generally limited to each day's accumulations.

In most places the storm snow overlies bare ground. At alpine elevations it covers a crust over 20 to 50 cm of old, wet snow.

Terrain and Travel Advice

  • Don't let storm day fever lure you into consequential terrain.
  • Start with conservative terrain and watch for signs of instability.
  • Continue to make conservative terrain choices while the storm snow settles and stabilizes.
  • Use extra caution around cornices: they are large, fragile, and can trigger slabs on slopes below.
