Avalanche Forecast

On Monday, several size 2 wind slab avalanches were observed in cross-loaded features below treeline. These avalanches are suspected to be +48 hours old. See the South Rockies Feild Team MIN report for a good visual representation of this problem.

If you go out in the backcountry, please consider sharing your observations on the Mountain Information Network (MIN).

New snow is accumulating over faceted surfaces in many areas and wind-affected surfaces in open areas at all elevations. A weak layer of facets above a melt-freeze crust is found down 60 to 100 cm.

The mid and lower snowpack is generally well bonded with a series of crusts and facetted snow.

The average snow depth at treeline is approximately 100 to 180 cm.

Tuesday Night

Mainly cloudy with isolated flurries, 5 to 10 cm of low-density snow, westerly alpine wind 20 to 40 km/h, treeline temperature -15 °C.

Wednesday

Cloudy with scattered flurries, 10 cm of snow across the region, local hot spots may see up to 20 cm of low-density snow, southwest switching to northeast alpine wind 10 to 30 km/h, treeline temperature -18 °C.

Thursday

Mostly sunny with no new precipitation, northeast alpine wind 10 to 20 km/h, treeline temperature -20 °C.

Friday

Mostly cloudy with isolated flurries, trace amounts of snow, southwest alpine wind 20 to 40 km/h, treeline temperature -12 °C.

• Watch for fresh storm slabs building throughout the day.
• Be especially cautious as you transition into wind affected terrain.
• Be aware of the potential for loose avalanches in steep terrain where snow hasn't formed a slab.
• Use appropriate sluff management techniques.
