Regions

South Coast.

Some models forecast up to 50 cm snow accumulating by the end of the day Friday. Avalanche hazard will increase as rain turns to snow and storm slabs develop.

Confidence

Low - Intensity of incoming weather systems is uncertain on Friday

Weather Forecast

WEDNESDAY NIGHT: Cloudy with clear periods and isolated showers. Freezing level 1500 m. Alpine low +2. Moderate gusting strong southeast wind.THURSDAY: Rain with wet snow in the alpine, 18-23 mm. Freezing level 1500 m. Alpine high +3. Moderate gusting strong southeast wind.FRIDAY: Snow and rain, 40-50 cm. Freezing level 1600 m. Alpine high +3. Moderate to strong south wind.SATURDAY: Snow, 20-25 cm. Freezing level 1500 m. Alpine high +2. Moderate south wind gusting strong to extreme.More details can be found in the Mountain Weather Forecast.

Avalanche Summary

No recent avalanche observations have been reported. On Friday, loose wet avalanches released naturally below 1200 m. Skiers were able to trigger loose wet avalanches which ran on an ice layer down 15-20 cm. Size 2 wet slabs were also observed in the Sky Pilot area are thought to have occurred on Thursday or Friday.We appreciate any observations shared on the Mountain Information Network here.

Snowpack Summary

Warm temperatures have created moist surface snow, which has refrozen into crusts. The snowpack is well settled. Snowpack depths have shrunk considerably below tree line.In the north of the region, you may find wind-affected snow or dry snow (on shady aspects) at upper elevations. Lingering cornices may fail with warming with added loading from rain or snow. A solid surface crust exists below about 1700 m.

Problems

Wind Slabs

Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.

Storm Slabs

Storm Slab avalanches are the release of a cohesive layer (a slab) of new snow that breaks within new snow or on the old snow surface. Storm-slabs typically last between a few hours and few days (following snowfall). Storm-slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
