Kootenay Boundary

A hard melt-freeze crust extends to mountain top, decreasing the likelihood of avalanche activity. Continue to practice safe travel techniques, such as giving cornices a wide berth.

High

• We are confident due to a stable weather pattern.
• The snowpack structure is well understood.

Many small, natural wet loose avalanches and cornice falls released over the past few warm days.

Looking forward, a cooling trend will reduce the likelihood of triggering avalanches.

Please consider sharing your observations to the MIN.

A hard melt-freeze crust exists to mountain top. Another thick crust from mid-March is buried 30 to 40 cm deep. These crusts make triggering any deeper layers unlikely.

The mid and lower snowpack is strong in most areas. Snowpack depth tapers rapidly at lower elevations.

• Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.
• The snowpack is generally stable; it may be appropriate to step out into more complex terrain.
• Pay attention to cornices and give them a wide berth when traveling on or below ridges.
