Regions: South Coast.
Confidence
Good - -1
Weather Forecast
Warm daytime temperatures and freezing down to the valley bottoms is expected over the weekend. The freezing level is forecast to rise to about 2000 metres on both Saturday and Sunday. Expect mostly sunny skies and light south to southeast winds through the forecast period.
Avalanche Summary
Explosive control along the Coquihalla corridor produced large avalanches up to size 3.5 from cornice falls pulling slabs on the slopes below. South aspects produced large avalanches running to near full path in the Duffey Lake area. Expect to see continued activity on solar aspects until we get a freeze in the alpine.
Snowpack Summary
Thin sun crusts are developing on steep solar aspects. The recent storm snow continues to settle and bond in the Duffey Lake area due to the warm temperatures and light winds. Recent cornice growth may be easy to trigger with light loads or from solar radiation. The Coquihalla area is also experiencing warm temperatures and light winds. The storm slab in the Coquihalla is about a metre deep and continues to settle and bond with warm temperatures. Concern for steep solar aspects in the alpine with shallow or variable snowpack depths.
