Northwest Inland

Wind slabs may have formed at higher elevations, approach ridgelines and mid slopes rollovers with caution.

There is no new avalanche activity to report.

If you do go into the backcountry, consider submitting a Mountain Information Network report.

10-25 cm of new snow has fallen over previously wind-affected surfaces at higher elevations.

Two different surface hoar layers have been reported in the upper snowpack and appear to be most prominent at treeline and below. Snowpack depth at treeline is 50 to 100 cm.

Thursday Night

Cloudy with 5-10 cm of snow, southerly winds 70-100 km/h. Freezing levels remain above 1000 m until morning.

Friday

Mostly cloudy with 2-5 cm of snow, southwest winds 30-50 km/h, treeline high temperature -1 °C, freezing levels fall from 700 m to valley bottom by afternoon.

Saturday

Increasing cloud with a chance of flurries, and southerly winds 50-60 km/h. Treeline temperatures -4 °C, freezing level at valley bottom.

Sunday

Cloudy with light snowfall. Freezing levels rise to 1500 m, treeline temperatures around -1 °C. Strong southerly winds, 60-100 km/h.

• Pay attention to the wind, once it starts to blow fresh sensitive wind slabs are likely to form.
• Carefully assess open slopes and convex rolls where buried surface hoar may be preserved.
• If triggered, wind slabs avalanches may step down to deeper layers resulting in larger avalanches.
