    Freezing levels are expected to drop on Wednesday, and loose wet avalanches will become much less likely. If warming persists, watch for loose wet avalanches in steep, sun-exposed terrain.

Confidence

Good

Weather Forecast

The current ridge of high pressure will break down on Wednesday. By late in the day, a weak pacific system will bring light snowfall which should last until Thursday evening (up to 5cm in total). On Friday, we can expect clearing skies as the ridge is expected to rebuild. Winds are forecast to be strong from the southwest with the pulse of moisture, and then ease to moderate and northwesterly by Friday. Freezing levels should hover around 1500m with the snowfall, and then drop to about 1000m on Friday

Avalanche Summary

No new avalanches have been reported.

Snowpack Summary

On high north-facing terrain. light amounts of cold, lower density snow overlie a widespread thick hard crust . Below about 2000m there is no snow on the crust and surface runnels show the effect of last week's rain showers. Sun-exposed slopes have become moist, or wet with recent daytime warming and solar radiation. Below the surface crust, the snow is still moist; however, the mid and lower snowpack are generally strong and well-consolidated. Most of the terrain below treeline is below threshold for avalanche activity.
