New snow and wind will start to develop storm slabs. Recently buried surface forms may not bond well to the new snow.

Weather Forecast
Overnight and Sunday: Light snow in the morning but picking up in the evening with an associated increase in westerly winds. Expect 5-10cm and moderate to strong westerly winds by the end of the day. Freezing levels should remain in valley bottoms.Monday: Continued moderate to locally heavy snowfall with the heaviest amounts likely on the east of the divide. Strong winds shifting to north-easterly as the temperatures drops.Tuesday: Becoming clear and cold with North-easterly winds.
Avalanche Summary
Smooth alpine slopes that did not previously slide may still be of concern. With very little data on the current conditions, you need to be your own detective out there. If you see or trigger an avalanche, please send us a note at: [email protected].
Snowpack Summary
Treeline snowpack depths in sheltered areas vary between approximately 40-100 cm. The current snowpack has been subjected to strong wind, cold temperatures and chinook driven warming. As a result it should be easy to find wind scoured snow, old wind slabs, crusts and faceted snow. Crusts with associated facets may be lurking near the base. This weakness may still be of concern on isolated smooth terrain features that have not seen avalanche activity.
