Regions

Little Yoho.

Friday should start with a good freeze but hazard will increase as the day warms up. Our danger ratings are for the highest level we expect to see over the course of the day, but these van vary wildly this time of year.

Weather Forecast

Continued nice weather on Friday. We should see a decent overnight freeze with 3000m temperatures reaching -5 and valley bottoms up to +5. Winds will be moderate to strong at 3000m and light at treeline. A significant warmup with high solar input is expected Saturday and Sunday.

Snowpack Summary

10-20cm recent snow, lies over firm surface crust on south aspects up to at least 2600 m with softer snow found on north aspects. Minimal recent wind effect at higher elevations except in exposed ridge crests Profile at 2400m on Mt. Ogden found facets down 65cm with no results on column test. Cornices are huge!

Avalanche Summary

No new avalanches reported today. Large sluffing in the alpine was occurring from a brief intense squall Wednesday, and a cornice fall resulted in a size 2.5 avalanche on the cliffs above the approach to Mt. Ogden., occurring in the past couple of days.

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.
