Regions: Glacier.

Expect travel conditions below 2200m to be rugged in the refrozen snowpack.  Watch for storm slab and avalanche hazard as you move into the alpine.

Weather Forecast

Flurries will bring 2cm today accompanied by gusty north winds. High pressure will bring cold clear conditions for Sunday. Monday the next storm system comes bringing periods of snow.

Snowpack Summary

The midweek warm, wet, storm brought heavy rainfall as high as 2400m. Upper elevations received over 50cm of storm snow accompanied by extreme west winds that raked the alpine. The storm ended with a rapid cooling trend refreezing rain soaked snow. The cooling trend was accompanied by light snowfall partially softening the crusted surface.

Avalanche Summary

A significant loose wet avalanche cycle occurred with the last storm with slides up to size 3 along the highway corridor. No new avalanches observed in the last 24hrs.

Confidence

Due to the number and quality of field observations

Avalanche Problems

Storm Slabs

Heavy snowfall midweek, accompanied by extreme westerly wind has formed slabs in the alpine. These slabs may remain active in the high alpine.

  • The new snow will require several days to settle and stabilize.
  • Use caution in lee areas. Recent wind loading has created wind slabs.

Aspects: North, North East, East, South East, South.

Elevations: Alpine.

Likelihood: Possible

Expected Size: 1 - 3
