Regions

South Coast Inland.

A springtime melt-freeze regime is establishing itself in the South Coast Inland region. Read more about how to manage avalanche danger under current conditions in our Forecaster's Blog here.

Confidence

Moderate - Due to the number of field observations

Weather Forecast

Monday: A mix of sun and cloud with isolated wet flurries. Light north winds. Freezing level to 1900 metres with alpine temperatures of -1.Tuesday: A mix of sun and cloud with isolated wet flurries. Light southwest winds. Freezing level to 2000 metres with alpine temperatures around 0.Wednesday: Mainly cloudy with scattered flurries and up to 5 cm of new snow. Moderate west winds. Freezing level to 1700 metres with alpine temperatures of -3.

Avalanche Summary

No new avalanches have been reported in the region. Please post your observations to the Mountain Information Network.

Snowpack Summary

Below a thin skiff of new snow from Saturday night, a melt freeze cycle has allowed for surface crust formation down to about 1500 metres as of Sunday morning. The snowpack is generally well settled and strong, but basal weaknesses in the far north of the region remain a concern. With that said, the possible triggers for deep weaknesses in this part of the region are likely limited to large cornice falls.

Problems

Cornices

Cornice Fall is the release of an overhanging mass of snow that forms as the wind moves snow over a sharp terrain feature, such as a ridge, and deposits snow on the downwind (leeward) side. Cornices range in size from small wind drifts of soft snow to large overhangs of hard snow that are 30 feet (10 meters) or taller. They can break off the terrain suddenly and pull back onto the ridge top and catch people by surprise even on the flat ground above the slope. Even small cornices can have enough mass to be destructive and deadly. Cornice Fall can entrain loose surface snow or trigger slab avalanches.
