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.

Problems

Wind Slabs

Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
