Crowsnest North

Wind slabs are expected to form over the day. Watch for fresh and reactive slabs near ridgelines.

Moderate

• We are uncertain due to the variability of wind effect on the snowpack.
• The snowpack structure is well understood.

Small loose wet avalanches were reported on Sunday. Last week's rain and warm temperatures produced a widespread wet avalanche cycle. Moving forward, we expect reactivity to rider triggers in wind-loaded terrain features.

If you are heading into the backcountry, please consider sharing conditions via the MIN.

By Tuesday afternoon, up to 10 cm of new snow may have fallen, redistributed into deeper deposits on north and east facing slopes. New snow sits over a melt-freeze crust, which will likely bond poorly.

The snowpack below is moist to ground, and well consolidated. The snowpack rapidly tapers at lower elevations.

• Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.
• Pay attention to cornices and give them a wide berth when traveling on or below ridges.
• Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
