Weather Forecast

Saturday a ridge of high pressure passes over our area giving clear skies, light winds from the west and freezing levels as high as 1800m.Sunday a "cold" low moves inland.  Giving increasing cloudiness, moderate to strong SW wind, light precipitation and lowering freezing levels through Monday.  Total snowfall accumulations will be 3-5cm.

Snowpack Summary

Up to 20cm of settling new snow overlies a supportive melt-freeze crust which extends into the alpine on all aspects. The mid and lower snowpack is generally well consolidated with no notable shears and no recent activity to indicate a persistent weakness.

Avalanche Summary

No new activity has been observed, suspect that some small loose snow and storm slab avalanches have occurred as a result of the storm.

Confidence

Intensity of incoming weather systems is uncertain
