Regions

Little Yoho.

A return to spring conditions on Sunday. Expect good conditions in the AM with rising danger on solar aspects starting in the early afternoon. SH.

Weather Forecast

A clearing trend overnight into Sunday should provide a decent freeze. We will return to a more regular spring freeze/thaw pattern for the next couple of days, with strong diurnal swings. Alpine temperatures should stay below zero on Sunday with light Northerly winds.

Snowpack Summary

A very weak freeze overnight was barely holding the snow together today at treeline and below treeline Saturday, with isothermal snow one forecaster likened to clam chowder underneath. Solar aspects in the alpine were becoming moist today, with mainly dry powder on northerly aspects.

Avalanche Summary

Numerous loose wet slides on steep solar aspects in the alpine to sz. 1.5 today in the Sunshine Village area.

Confidence

Freezing levels are uncertain on Wednesday

Problems

Loose Wet

Loose Wet avalanches are the release of wet unconsolidated snow or slush. These avalanches typically occur within layers of wet snow near the surface of the snowpack, but they may quickly gouge into lower snowpack layers. Like Loose Dry Avalanches, they start at a point and entrain snow as they move downhill, forming a fan-shaped avalanche. Other names for loose-wet avalanches include point-release avalanches or sluffs. Loose Wet avalanches can trigger slab avalanches that break into deeper snow layers.
