Snowfall amounts across the region are variable, if the area you are travelling in has greater than 20 cm of snow, storm slabs are a concern.
Be willing to adjust plans to changing conditions.
Low density storm snow is forecasted for the region with the greatest amounts near Elkford where greater than 20 cm is possible. Where snowfall amounts are greatest storm slabs are possible, elsewhere dry loose is more likely.
On Sunday, several size 1 to 1.5 dry loose avalanches were reported in the region. In nearby Waterton, storm slab avalanches were observed.
Storm snow amounts are variable across the region with higher amounts forecasted to fall through Tuesday around Elkford. Up to 20 cm of snow will add to the 10 cm that accumulated on Monday, bringing storm slab totals to roughly 30 cm.
Storm slabs are building over old surfaces of:
wind-pressed snow in high elevation lees
crust on exposed windward features, south aspects and low elevations
soft, faceted snow, possibly topped with small surface hoar crystals in sheltered areas.
The remainder of the snowpack is well consolidated, containing a number of crusts which are not of concern at this time.
