Regions: North Okanagan, Shuswap.

The snowpack consists of multiple buried weak layers. The likelihood of triggering avalanches is decreasing, however, if you do the consequences could be very high.

Confidence

Moderate

Avalanche Summary

No recent avalanche activity has been reported in the region. However, there have been several recent reports of large human-triggered avalanches in neighboring regions.

Please continue to share any observations or photos on the Mountain Information Network.

Snowpack Summary

Roughly 40 to 50 cm of new snow continues to settle and bond over a weak layer buried just before Christmas. This layer consists of sugary faceted grains and/or small surface hoar.

The mid and lower snowpack generally remains weak and facetted, with a number of weak layers present. A layer of particular concern that was buried in November, consists of weak facets, surface hoar, and/or a thin crust, and is near the bottom of the snowpack.

Snowpack depth is roughly 150 cm at treeline.

Weather Summary

Monday night

Mostly clear with no precipitation. Light southerly winds. -5 C at treeline.

Tuesday

A mix of sun and cloud, no precipitation. Light southerly winds. -5 to -10 C at treeline.

Wednesday

A mix of sun and cloud, no precipitation. Light southerly winds. -10 C at treeline.

Thursday

A mix of sun and cloud, no precipitation. Light easterly winds. -5 to -10 C at treeline.

Terrain and Travel Advice

  • Keep in mind that human triggering potential persists as natural avalanching tapers off.
  • Avoid thin areas like rock outcroppings where you're most likely to trigger avalanches failing on deep weak layers.
  • Watch for signs of instability like whumpfing, hollow sounds, shooting cracks or recent avalanches.

Avalanche Problems

Persistent Slabs

Multiple weak layers persist deep in the snowpack. Much of the near-by avalanche activity has occurred in generally shallow areas with variable snow depths. Larger-than-expected avalanches are possible due to the likelihood of avalanches stepping down to deeper weak layers.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Unlikely - Possible

Expected Size: 2 - 3.5
