Avalanche Forecast
Regions: Little Yoho.
Beautiful weather for the weekend with an inversion setting up for Sunday-Monday, bringing warmer temperatures aloft. Watch for solar heating at upper elevations; there's some uncertainty about whether this will have a significant impact on the snowpack.
Confidence
Moderate
Avalanche Summary
No new avalanches observed or reported in the forecast region today. On Friday a few natural wind slabs were observed in the Ogden region to size 1.
Snowpack Summary
The wind effect exists in the high alpine, but many sheltered areas have soft snow. The mid-pack is generally strong; however, a facet layer can be found near the ground in shallow snowpack areas. At treeline, average snowpack depth ranges from 110 to 160 cm.
Weather Summary
High pressure will dominate the forecast region for the next few days. Valley bottoms will see temps ranging from 0°C to -15°C. A temperature inversion will form at 3000m on Sunday, with temperatures staying around 0°C through Tuesday. Moderate north winds at ridge crest. Clear skies and warm alpine temps may lead to significant heating on south aspects.
Avalanche Problems
Wind Slabs
We have seen a few small windslabs triggered in steep alpine terrain, but many areas exist where this is not a problem. If you are venturing into steep alpine terrain and the surface is wind affected, be careful as this might be enough of a problem to ruin your day.
Aspects: North, North East, East, South East, South.
Elevations: Alpine.
