Regions: Little Yoho.

A little more storm snow and a little more hazard in Yoho today. Windslabs and windloaded open areas will have to be managed carefully. Pay attention to rotten tree-wells.

Weather Forecast

A little bit of everything except spring. Some upper winds, more snow, clouds and clear breaks. Models vary, but it is reasonable to expect 10cm more snow on Friday, Next week we dip into some cooler temps and more snow, Hopefully we get some sun and warmer temps by the end of the week.

Snowpack Summary

Recent winds have created windslabs and buried windslabs. Over 40 cm of storm snow in some areas of Yoho on suncrusts or facets remains a tricky problem.

Avalanche Summary

Poor visibility limited observations today. No natural avalanches were reported.

Confidence

Avalanche Problems

Wind Slabs

Be careful with wind loaded pockets, especially near ridge crests and roll-overs.Pay attention to overhead hazards like cornices which could trigger slabs.

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

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 2.5

Persistent Slabs

Recent snow may be more sensitive to human triggering on solar aspects where it sits on sun crustWatch for signs of instability such as whumpfing, or cracking.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 2.5
