South Coast

Fair - Intensity of incoming weather is uncertain on Friday

Thursday: Another 2-4cm before the snowfall tapers off in the morning, with 5-10cm total storm snow. Moderate southeasterly winds are expected to shift to clearing in the afternoon. Freezing levels should remain in valley bottoms. Friday: Light snow with another 5cm possible. Moderate southerly winds and freezing levels rising to 1000m. Saturday: Light snowfall starting in the afternoon with 5-10cm expected. Moderate to strong southewesterly winds and freezing levels as high as 1700m in the morning but dropping throughout the day.

There have been no new reports of avalanches. Fresh soft wind slabs are expected to form and become an avalanche problem.

Large surface hoar and faceted powder on sheltered shady slopes, and a surface crust on sun-exposed slopes, is now lightly buried in some locations and should continue to get incrementally buried over the forecast period. Assuming the structure of this current snow surface is preserved long enough for a sufficiently thick and cohesive slab to bury it, then a highly unstable situation should develop. Particularly where surface hoar and/or faceted crystals are associated with a weak crust. Generally speaking the longer surface snow is exposed to the elements before it gets burred, the more likely it is to become a serious problem given favorable conditions for slab development. The mid and lower snowpack are generally well settled and strong, but faceted. Check out the Forecaster's Blog link below for more general snowpack discussion and good advice.
