South Coast

It's still winter in the mountains. Watch for storm slabs that sit on crusts, surface hoar and/or facets at upper elevations. These slabs may be surprisingly deep on leeward slopes near ridge crests.

Moderate - Due to the number of field observations

SUNDAY: Increasing cloud and flurries in the afternoon. Accumulation trace. Ridge wind light, southwest. Temperature at treeline near -3. Freezing level 800 m.MONDAY: Cloudy, flurries. Accumulation 10-15 cm. Ridge wind light, southwest. Temperature at treeline near -2. Freezing level 1000 m.TUESDAY: Cloudy, flurries or light rain. Precipitation 10 -15 mm. Ridge wind moderate, southwest. Temperature at treeline +2. Freezing level rising to 1600 m.

Thursday morning ski cutting work on the North Shore mountains produced loose, dry storm snow releases (size 1) above 1000 m and loose, wet size 1 releases below 1000 m.There have been no reports from the northern part of the region around Squamish, however it's likely that a natural avalanche cycle occurred in high alpine terrain with the recent storm.

Around 45 mm of precipitation has fallen since Thursday. Rain transitioned to snow above 1000 m Thursday morning which produced about 25 cm of snow with light to moderate east/southeast wind. The warm to cold nature of the storm has allowed the new snow to bond well to the old surface up to treeline. The alpine likely saw very little if any rain and more snow/wind. Up high the new snow is likely sitting on a mixture of weak grains including a crust on solar aspects and potentially facets/surface hoar on polar aspects. Below the recent storm snow the snowpack is generally well settled and strong.
