Weather Forecast

The warm warm temperatures and sunny skies of today will be replaced by cooler temperatures and precipitation as a Pacific cold front crosses the coast and moves into the South Coast Inland area. SUNDAY: Freezing level lowers briefly to around 1000 m. overnight, and 15 to 20 cm of snow possible, light southwest winds are forecast. MONDAY: Sunny skies with some cloudy periods, precipitation forecast for early in the morning, clearing up in the afternoon, freezing level climbing to 1700 m, winds from the south. TUESDAY: Freezing level from Monday night will be the low for the next few days at 1200 m. Temperatures will rise close to 2500 m. in the next few days as a ridge of high pressure begins its domination of the weather forecast for the remainder of the week.For more detailed mountain weather information visit: https://avalanche.ca/weather

Avalanche Summary

Reports from yesterday tell of new snow sluffing in steep terrain on melt freeze crusts, along with loose-wet avalanches up to size 1.5.

Snowpack Summary

10 to 20cm of recent storm snow overlies multiple solar and melt-freeze crusts on all aspects up to 2000 m. Slightly more snow fell in the south of the region where they received 20 to 25 cm of snow. The storm featured moderate south/southwest winds that formed wind slabs on lee slopes around treeline and above. Below the new snow, the snowpack is strong and well-settled throughout with no notable persistent weaknesses, however, cornices are are reported to be huge and fragile.
