Avalanche Forecast

Low

Over the past few days, both ski hills have triggered deep slabs up to size 2 with explosives or sometimes with a ski cut after the explosive failed to trigger the slope. Parks Forecasters have noted large whumphs in the Sunshine Backcountry on Tuesday and in the O'hara region on Wednesday. No new naturals have been observed for the past few days.

20-60 cm of snow has formed a slab over a very weak base consisting of facets. Thin crusts can be found on the facet interface at lower elevations and on solar slopes. Snowpack depths at treeline range between 60 and 120 cm. Below treeline, small sluffs may be triggered in steep features where the ski and foot penetrations are to the ground in a very weak facetted snowpack,

Friday: Alpine high -10, low -20. Winds moderate to strong NW. In the late afternoon and overnight, there may be localized heavy flurries with the descent of a strong cold front. On the Eastern slopes, we may see up to 10 cm, elsewhere, 2-5 centimetres.

Saturday: Alpine high -20, dropping to -25 throughout the day. Alpine winds will ease to light NE. 5 cm of snow.

Sunday: Alpine temperatures will continue to cool -25 to -35 range with light NE winds. Expect some clouds and light flurries on the East slopes.

• Fresh snow rests on a problematic persistent slab, don't let good riding lure you into complacency.
• Uncertainty is best managed through conservative terrain choices at this time.
