Regions

Little Yoho.

Our danger ratings reflect the highest level we expect to see over the course of the day. Rising temperatures and solar heating can be expected to increase avalanche danger. Start early and finish early to take advantage of the overnight recovery.

Weather Forecast

A solid freeze Monday morning can be expected after passage of a cold front overnight. Winds will diminish to light and shift west and partly cloudy skies in the morning should give way to clearing. While a strong solar effect can be expected on steep solar slopes, temperatures should remain cooler than they have been through the weekend.

Snowpack Summary

10-20cm of recent snow remains preserved on Northerly aspects with a skiable temperature crust below 1700m. On solar aspects substantial surface crusts have formed. Extensive wind effect in the alpine with isolated sheltered areas. Recent profiles show the Feb. 19 and Jan. 27 facets in the upper meter with hard to no results. Cornices are huge!

Avalanche Summary

A natural avalanche cycle up to size 2 occurred Saturday typically originating as point releases from steep, rocky solar terrain with isolated examples of slabs originating from very thin features. The solar crusts that were created Saturday generally held Sunday especially at higher elevations where winds were moderate gusting strong.

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.
