A few natural size 1 wind slabs were reported from the far north of the region. They occurred on south/southwest facing terrain and likely formed in response to redistribution of surface snow by recent strong northerly winds

Fair - Due to the number of field observations

Wednesday will see a mix of sun and cloud with generally light southwest winds. By Thursday afternoon a stronger weather system will impact the region bringing more steady snowfall and strong southwest winds. Freezing levels will hover around valley bottom on Wednesday rising to 800 metres for the rest of the forecast period.

A dusting of new snow overlies a variety of surfaces which include wind slabs in alpine terrain, hard rain crusts at lower elevations and weak surface hoar crystals. Last week's heavy rain affected southern parts of the region up to alpine elevations, while the far north remained drier and sports a weaker snowpack in general. Areas which previously received rain have probably now formed a hard frozen crust. Upper elevation terrain and far northern areas are likely to have wind slabs and large fragile cornices. Deeper in the snowpack, weaknesses such as the mid-November crust-facet layer still exist. Avalanches at this interface have become unlikely, although the consequences of a release remain high. This layer may be more sensitive to triggering in steep, unsupported high alpine terrain, or in the far north of the region.
