Avalanche Summary

No avalanches were observed or reported in Yoho on Tuesday.

Snowpack Summary

There is up to 15cm of settled storm snow at treeline over top of well developed crusts on solar aspects (to ridgetop), and on crusts at all aspects treeline and below. On north facing alpine slopes there is 20-30 cm of dry snow over firmer surfaces. A settled mid-pack sits over the Jan facets down 90 to 150cm, with a well settled lower snowpack below.

Weather Summary

Clear skies and light winds bring stable conditions. Valley temperatures will reach near 5°C, while ridgetops remain seasonably cold around -8°C. A cool, quiet pattern for early starts and fast travel.

Terrain and Travel Advice

Even brief periods of direct sun could produce natural avalanches.

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.
