Avalanche Summary

No reports of avalanches received from Sunday.

Thanks for the observations and please continue to post your reports and photos to the Mountain Information Network. It is really helpful for forecasters!

Snowpack Summary

Sunday's storm delivered around 30cm of snow near treeline with a bit more more still falling Monday. This is covering rain runnels from last week's rain which saturated the snowpack at all elevations and pretty much removed all layering.

Weather Summary

Monday Night: 5 to 15 cm of snow above 800m. Light southwest wind. Treeline temperature just below zero.

Tuesday: Trace to 10 cm of snow above 800m. Light southwest wind. Treeline temperature just below zero. Overcast or foggy.

Wednesday

Snow arrives again overnight and during the day with 60 to 80 mm of water equivalency forecast. Freezing level remains steady around 1000m but wet snow as low as 600 m during the peak of the storm. Strong south winds.

Thursday

Dry. Mostly sunny with low elevation cloud. Light NW wind. Freezing level around 500 m with treeline temperatures a few degrees below zero.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Be careful to keep storm day fever from luring you out into bigger terrain features.
  • Minimize exposure during periods of heavy loading from new snow and wind.
  • Avoid terrain traps such as gullies and cliffs where the consequence of any avalanche could be serious.
  • The new snow may require another day to settle and stabilize.

Avalanche Problems

Storm Slabs

The problem is most likely at higher elevations on steeper slopes where more than 25 cm of snow accumulates, especially if it's dry or wind driven snow.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 2
