Avalanche Forecast
Regions: Kootenay Boundary.
Continue to make conservative terrain choices. The storm snow likely hasn't bonded to the underlying crust.
Confidence
Moderate - The snowpack structure is generally well understood.
Weather Forecast
Monday night: Flurries bringing up to 5 cm of new snow with moderate west winds. Low of -3 at 1500 m.
TUESDAY: Mostly cloudy with light flurries bringing up to 5 cm of new snow. Moderate west wind and freezing level around 1500 m.

Avalanche Summary
Early reports on Monday indicate small storm slabs were reactive to ski cuts. Several size one natural cornice falls were also reported.
Snowpack Summary
New wind and storm slabs have formed throughout the day on Monday. Below this new snow a crust exists on all aspects and elevations. This crust will likely be found near the surface at lower elevations and become moist as the freezing level rises.
Multiple crusts exist in the upper snowpack. The mid and lower snowpack are well settled.
Terrain and Travel
- Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
- Continue to make conservative terrain choices while the storm snow settles and stabilizes.
- Closely monitor how the new snow is bonding to the crust.
Avalanche Problems
Storm Slabs
New storm and wind slabs will have form throughout the day on Monday. Size and sensitivity to triggering will be greatest near ridge crests and steep roll overs on north and east facing terrain where wind loading is likely to occur.
Aspects: All aspects.
Elevations: All elevations.
Likelihood: Likely
Expected Size: 1 - 2
