Regions

Little Yoho.

Spring like conditions exist. Pay attention to how quickly the day warms up and how strong the recovery there is at night.

Weather Forecast

Wednesday will be mainly cloudy with some isolated flurries at upper elevations. Freezing levels will rise to 2100 m. Continued warm temperatures with little precipitation through the end of the week.

Snowpack Summary

Generally a well settled snow pack exists with moist snow on solar aspects below 2000 m. Very isolated wind slabs may be found near ridge tops in the alpine.

Avalanche Summary

One skier triggered wind slab (size 1.5) on a south slope at 3000 m reported from the Wapta on Tuesday. Several loose wet avalanches up to Class 1.5 on solar aspects.

Confidence

Freezing levels are uncertain

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.
