Regions: Banff Yoho Kootenay.

Forecasted cooler temperatures and cloud cover will keep the lower elevation hazard at LOW. This hazard could increase quickly if we receive warmer and sunnier conditions than expected.

Weather Forecast

Forecasted freezing level will stay near valley bottom till Monday with minimal fluctuatingÂ between daytime highs and overnight lows. Light precipe overnight Saturday could bring snow accumulation of 5cm to the forecast region. Strong westerly winds are expected at ridge top.

Snowpack Summary

5-10 cm of new snow fell Friday with rain below 1800m. The new snow now buries sun crust on steep solar aspects (East to West) into the Alpine, a temperature crust on all aspects below 1800m and Surface hoar up to 10mm located in isolated, shaded areas.

Avalanche Summary

No new avalanches observed or reported today.

Wind Slabs

Small isolated wind slabs can be found on lee slopes in the alpine. Expected this new slab development to overlay a sun crust on solar aspects.

Be careful with wind loaded pockets, especially in steep confined alpine terrain.

Aspects: North, North East, East.

Elevations: Alpine.

Likelihood: Possible

Expected Size: 1 - 1.5
