Regions

South Coast Inland, Birkenhead, Duffey, South Chilcotin, Stein, Taseko.

There's no better time to chase your big spring objectives. Bring sharp tools, keep track of cornices in overhead terrain, and start and finish early to avoid isothermal conditions.

Confidence

High

We have a good understanding of the snowpack structure and confidence in the weather forecast.

Avalanche Summary

No new avalanches were reported Tuesday and the trend of diminishing activity continues.

Explosives control in the Duffey corridor on Monday produced mainly small wet loose avalanches but also a few slabs up to size 1.5. One of these failed on the 30 - 40 cm-deep late-March crust.

Wet loose activity to size 2 and several wind slabs were reported on Sunday. Check out the report for one of the wind slabs HERE.

If you get out, post a MIN!

Snowpack Summary

Spring-like melt-freeze cycles now characterize a daily evolution of surface conditions on all but north-facing slopes above 2000 m, where about 10 cm of dry snow may still be found. It overlies old wind-affected snow above this elevation and a firm crust below.

Two older crusts exist 1-1.5 m deep at treeline and above. Concern for these layers is limited to high north aspects where large cornice fall may have enough force to trigger a slab. The mid and lower snowpack are otherwise well settled.

Weather Summary

Wednesday Night
Clear skies. 10 km/h north ridgetop wind. Treeline temperature -1 °C. Freezing level 1900 m.

Thursday
Sunny. 5 to 10 km/h northeast ridgetop wind, easing. Treeline high temperature 4 °C. Freezing level to 2400 m.

Friday
Sunny before clouding over near end-of-day. 20 to 30 km/h south ridgetop wind. Treeline high temperature 6 °C. Freezing level to 2600 m.

Saturday
A mix of sun and cloud with scattered light rain, less than 1 mm. 15 km/h variable ridgetop wind. Treeline high temperature 7 °C. Freezing level 2700 m.

Terrain and Travel Advice

Limit exposure to steep, sun exposed slopes, especially when the solar radiation is strong.
Rocks will heat up with daytime warming and may become trigger points for loose wet avalanches.
Pay attention to cornices and give them a wide berth when traveling on or below ridges.
Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.

Problems

Cornices

Cornice Fall is the release of an overhanging mass of snow that forms as the wind moves snow over a sharp terrain feature, such as a ridge, and deposits snow on the downwind (leeward) side. Cornices range in size from small wind drifts of soft snow to large overhangs of hard snow that are 30 feet (10 meters) or taller. They can break off the terrain suddenly and pull back onto the ridge top and catch people by surprise even on the flat ground above the slope. Even small cornices can have enough mass to be destructive and deadly. Cornice Fall can entrain loose surface snow or trigger slab avalanches.

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.
