Regions

Northwest Inland.

Field observations from the Northwest Inland are scarce. Use this forecast as a starting point for assessing the distribution and reactivity of recent wind slabs.

Confidence

Low - Due to the number of field observations

Weather Forecast

Tuesday night: Cloudy with clear periods. Possible isolated flurries and trace of new snow. Moderate to strong west winds.

Wednesday: A mix of sun and cloud with a chance of isolated flurries and a trace of new snow. Moderate to strong west winds. Alpine high temperatures around -8 with freezing levels to 1000 metres.

Thursday: A mix of sun and cloud. Light variable winds. Alpine high temperatures around -6 with freezing levels to 1300 metres.

Friday: Increasingly cloudy with flurries developing over the day and continuing overnight. Up to 3 cm of new snow accumulating over the day. Light southeast winds. Alpine high temperatures around -6 with freezing levels to 1300 metres.

Avalanche Summary

There have been no recent reports of avalanche activity. If you're out we'd love it if you would submit what you're seeing to the Mountain Information Network.

Snowpack Summary

15-30 cm of new snow accumulated over the past week at upper elevations. This storm snow sits over a widespread, supportive melt-freeze crust from early April. Surface hoar and facets were previously observed on this crust on high north aspects. At lower elevations, ongoing warm weather has been promoting isothermal snowpack conditions and melting the snowpack away.

Problems

Wind Slabs

Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
