LOW avalanche danger does not mean NO avalanche danger. Watch for pockets of wind slab at higher elevations.

Summary

Confidence

High

Weather Forecast

Modified arctic air has drifted down from the north, pushed by light northerly winds and a noticeable absence of a jet stream. Valleys may continue to have low level clouds for the duration of the forecast period. Some thin high cloud may block the sun at times in the alpine, but generally the region should have broken skies for the next few days. There may be some very light precipitation in the form of flurries over the next few days, however at this time the region looks pretty dry until at least Wednesday. Alpine temperatures should be around -15 on Saturday, and closer to -10 on Sunday and Monday. Surface winds should be light southerly on Saturday and then start to build on Sunday as they become more westerly.

Avalanche Summary

No new avalanches reported. Minimal sluffing in steep terrain.

Snowpack Summary

Near surface facetting continues, and has resulted in loose dry snow mixed with new snow that is available for transport into wind slabs. These thin windslabs have developed over a mix of old surfaces left behind after the recent inversion and clear alpine skies. These old surfaces include surface hoar, near surface facets, and possible sun crusts on steep southerly aspects. Some areas of the western Cariboos around Wells Grey are reporting variable snow depths with treeline height of snow around 150 cm. Shallow snowpack areas may have weak facetted crystals near the ground.

Problems

Wind Slabs

An icon showing Wind Slabs
Thin wind slabs have been reported in isolated alpine areas in the immediate lee of terrain features. Some loose snow sluffing has also been reported from steep terrain.
Avoid cross loaded slopes at or above treeline.>Use ridges or ribs to avoid pockets of wind loaded snow. >Be cautious as you transition into wind affected terrain. >
