Regions: North Shore, Sasquatch, Sky Pilot, South Coast, Stave, Tetrahedron.

Cautiously assess conditions as you travel - the fresh snow may produce reactive slabs or, more likely, hide early-season hazards.

Avalanche Summary

No new avalanches have been observed or reported in the region, however, observations are limited at this time of year. If you head into the backcountry consider submitting a MIN report.

Snowpack Summary

Overnight snow will cover a melt-freeze crust and moist snowpack. Snow depths are 20-80 cm at upper elevations. The snow-dirt line is found around 1200 m, and most solar slopes and below treeline are below the threshold for avalanches.

Weather Summary

Saturday night

Heavy precipitation and extreme southwest wind will peak around midnight before temperatures cool and winds decrease. 20-35 mm precipitation overnight, ridgeline high +2 C, snow-rain line peaking around 1200 m.

Sunday

Up to 30 cm of new snow at upper elevations by morning. Strong northwest wind decreasing to moderate through the day, treeline temperatures dropping to -6 C, and freezing level dropping below 500 m.

Monday

Cold and sunny with patchy clouds. Light to moderate northeast wind, treeline temperatures around -10 C, and freezing level falling to valley bottom.

Tuesday

Cold, with a mix of sun and cloud. Moderate southwest wind, treeline temperatures around -8 C.

Terrain and Travel Advice

Investigate the bond of the recent snow before committing to your line.
Avoid freshly wind loaded terrain features.
Dial back your terrain choices if you are seeing more than 25cm of new snow.

Avalanche Problems

Storm Slabs

Strong winds with impacting upwards of 30 cm overnight snow likely formed reactive slabs, the deepest and most reactive deposits will be in open and wind-loaded areas. Be mindful that you may find reactive slabs lower on the slope than usual as a result of the strong winds.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Likely

Expected Size: 1 - 2
