Ongoing avalanche cycle in the Spray region. More snow than expected in the southern parts of the Spray. Very dangerous avalanche conditions. Travel in avalanche terrain not recommended.

Confidence

Low

Avalanche Summary

Evidence of an ongoing avalanche cycle is currently happening in the Spray valley.

Forecasters out in the dogleg area today had a skier accidental while skinning up in an open area in a steep below treeline feature. The avalanche was contained to the opening and no involvement. However this is excellent evidence of the current touchy conditions that exist.

Snowpack Summary

Well the storm finally produced some snow. The North end of the spray saw roughly 10cm of snow. When heading further South towards dogleg area, 25cm was found. This storm came in around -2 and with incredible winds from the west. We suspect significant windslab growth with the continuous winds and warm weather. The snow transport from mountain tops was impressive to watch. This new storm snow is sitting on top of the 10-20cm of snow that fell in early Feb. However all of this is now sitting on top of the Jan 30th interface along with the whole lower snowpack being faceted and weak.

Weather Summary

Sunday night an additional 5cm is possible with a night time low of -9.

Monday the snow will continue and 4cm throughout the day. The winds will remain pretty steady in the 60-75km/h range from the west. Slightly cooler temps.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Avoid avalanche terrain during periods of heavy loading from new snow, wind, or rain.
  • Wind slabs are most reactive during their formation.
  • Avoid steep terrain, including convex rolls, or areas with a thin, rocky, or variable snowpack.
  • Be careful as you transition into wind-affected terrain.

Avalanche Problems

Storm Slabs

Fresh touchy storm slabs exist in below treeline and treeline elevations.

Aspects: All aspects.

Likelihood: Very Likely

Expected Size: 1 - 2

Wind Slabs

Storm snow, strong winds and warm temps are sure to build new reactive slabs.

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

Elevations: Alpine, Treeline.

Likelihood: Very Likely

Expected Size: 1.5 - 3
