Lo esencial

Newly formed storm slabs will become larger and easier to trigger throughout the day.

Make conservative terrain choices and avoid overhead hazard.

    25 to 40 cm of new snow and strong southwest wind will form storm slabs that are reactive to human triggers.

Terrain and Travel Advice

  • Make conservative terrain choices and avoid overhead hazard.
  • Storm slab size and sensitivity to triggering will likely increase through the day.
  • Be aware of the potential for larger than expected storm slabs due to buried surface hoar.
  • Use small, low consequence slopes to test the bond of the new snow.
  • Watch for signs of instability like whumpfing, hollow sounds, shooting cracks, or recent avalanches.

Confidence

Moderate

  • We are uncertain about forecast snowfall amounts.

Avalanche Summary

Human triggered avalanches will become increasingly likely throughout the day on Thursday.

Snowpack Summary

Forecast snow and wind are expected to form reactive storm slabs overlying persistent weak layers.

At treeline and above, this layer is primarily a hard crust with weak facets above and/or below.

In sheltered treeline locations and below, this layer may be a combination of hard crust and/or surface hoar.

Cornices are reported to be large and looming. Be mindful of them overhead or when travelling on ridge tops.

The mid/lower snowpack is generally well settled and strong.
