Avalanche Problem 2: Persistent Slabs
What Elevation?
Which Slopes?
Chances of Avalanches?
Expected Size?
While it has been a few days since there has been any confirmed events directly associated with the March 15 crust, other crusts have now become buried in similar locations. Forecasters still voice caution with all of these potential sliding layers.
Travel and Terrain Advice
- Be cautious with convexities and steep slopes on solar aspects.
Avalanche Summary
3 skiers were hit from above by an avalanche and pushed approximately 500m down a couloir and onto a fan near Bow Lake yesterday. The debris spread out on the fan and all three skiers ended up on the surface. They sustained some injuries but were able to get back to their vehicle on their own. Lost skis, poles and other gear.
Snowpack Summary
10 - 20 cm of new snow over the last 48 hours with wind effect from moderate - strong SW winds. Buried temperature crusts exist to 2000m on all aspects and higher on solar slopes. The March 15 sun crust is down 25-50 cm on solar aspects in the alpine, this, and shallow areas harboring weak facets remain worth watching as temperatures slowly climb.
Weather Forecast
Temperatures will still remain relatively cool for the next few days, with valley temperatures barely reaching above zero. Snowfall starting late today will deposit up to 30cm by midday on Tuesday. Currently the wind is blowing from the East and we expect it to swing back around to the SW late Monday and it will remain in the moderate range.
