Regions

South Coast.

Successive storms will result in elevated danger, particularly in exposed, windy locations. There's a chance it may start to snow heavily a little earlier than expected on Wednesday. If so, adjust your objectives accordingly.

Weather Forecast

A series of storms is expected to bring further snow and wind to this region.Wednesday: Light snow during the day, getting heavier in the afternoon. Expect around 10 cm new snow during the day, then another 20-30 cm on Wednesday night. Freezing levels around 1000 m, which translates to a snow line of about 800 m. Moderate westerly winds, becoming strong southwesterly later on.Thursday: 5-10 cm new snow. Freezing levels around 1000 m. Moderate southwesterly winds.Friday: 15-20 cm new snow. Freezing levels around 900 m. Strong southwesterly winds.

Avalanche Summary

Expect human triggered and natural avalanches to occur in steep, wind-affected terrain at higher elevations.

Snowpack Summary

Recent heavy rainfall saturated the snowpack at all elevations and washed away much of the snow at lower elevations. Expect to find a crust buried under 20-30 cm of new snow. Travel in many places is rugged, with many open creeks and early season hazards, although Tuesday's heavy snow will be improving things. Snow depths at 1200 m are around 120 cm.

Problems

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.
