Weather Forecast
A strong southwest flow will bring Pacific moisture into the area through the middle of next week. The first major storm to reach the BC Coast arrives today, and will spread inland with a persistent mild southwest flow. Each successive system will bring warmer air and freezing levels will rise to 1700m on Sunday afternoon, dropping briefly Tuesday morning then rise again to 2300m by Tuesday afternoon.
Avalanche Summary
Reports of loose wet natural avalanches at lower elevations and numerous explosive controlled storm slabs up to size 2.5
Snowpack Summary
Deep storm slabs have developed in the alpine and at treeline above a variety of old surfaces that includes wind crusts, melt-freeze crusts, and weak facetted crystals in some areas. Shallow facetted areas at treeline may now be buried by 70-100 cm of wind transported new snow. Cooler temperatures have re-frozen the moist or wet snow at lower elevations into a solid base layer.
Problems
Storm Slabs
Storm slabs will continue to develop with each wave of Pacific moisture. Avalanche size and frequency are expected to increase throughout the weekend.
