Summary
Confidence
Good - The weather pattern is stable
Weather Forecast
Expect mainly sunny skies for the forecast period. Freezing levels will peak at about 2700m on Sunday, and then drop to about 2000m for Monday and Tuesday. Winds should remain light to moderate from the west.
Avalanche Summary
On Friday a skier remotely triggered a size 1 (15cm deep) wind slab in the alpine. Otherwise there has been little recent avalanche activity. Forecast warming may increase the likelihood of cornice failures and loose wet avalanches.
Snowpack Summary
North and west winds have created isolated wind slabs 5 to 10 cm thick on high elevation lee slopes. On other slopes you may find stubborn old wind slabs and surface facets. Melt-freeze conditions can be found on all solar aspects and at lower elevations. The snowpack is generally strong and well settled. However, large cornices may become weak with daytime warming.
Problems
Wind Slabs
Small wind slabs may remain sensitive to light loads in high elevation lee terrain. Due to the irregular wind pattern, wind slabs may be found in unsuspecting locations.
Give cornices a wide berth when travelling on or below ridges.>Be cautious as you transition into wind affected terrain.>Use ridges or ribs to avoid pockets of wind loaded snow.>
