Avalanche Forecast

Moderate

On Monday a field team member observed a large (size 2.5) 48-72 hour old natural avalanche that was triggered by a large cornice fall on the slope below it. This occurred on a north aspect.

Other than the above, we haven't received reports of recent avalanches. Looking forward, isolated pockets of wind slabs could be triggered by riders in steep lee terrain features.

Moderate to strong south winds are expected redistribute loose surface snow on Wednesday, potentially forming new wind slabs in exposed areas.

Winds will be acting on a light new snow amounts and the 5 to 10 cm of soft snow from the weekend that overlies a settled snowpack.

Snow depths at White Pass are around 100 cm in sheltered areas and 200 cm on wind-loaded slopes.

Tuesday night

Becoming cloudy. Light southeast winds increasing into the morning.

Wednesday

Cloudy with flurries bringing less than 5 cm of new snow. Moderate south winds, increasing with elevation. Treeline high temperatures around -10 °C.

Thursday

Partly cloudy, isolated flurries with trace accumulations. Light to moderate southwest winds. Treeline high temperatures around -10 °C.

Friday

Mainly cloudy. Light southwest winds. Treeline high temperatures around -5°C under a mild temperature inversion.

• Wind slabs are most reactive during their formation.
• Watch for signs of slab formation throughout the day.
• The best and safest riding will be on slopes that have soft snow without any slab properties.
