Summary
Confidence
Good - The weather pattern is stable
Weather Forecast
Expect a mix of sun and cloud for the forecast period. Ridge top winds should remain generally moderate from the northwest on Saturday and Sunday, and then become southwesterly on Monday. Freezing levels should hover around 2200m on Saturday, 2600m on Sunday, and 2100m on Monday.
Avalanche Summary
A few size 1 wind slabs have been triggered by skiers this week. No other avalanches have been observed.
Snowpack Summary
North and west winds have created isolated wind slabs 5 to 10 cm thick on lee slopes. On other slopes you may find tired old wind slabs, a sun crust on all solar aspects, surface hoar, surface facets, and/or up to 5 cm of soft snow over a widespread supportive rain crust in wind sheltered areas. 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.>
