Avalanche Forecast

Several size 1 natural glide avalanches were observed in the last 24 hours near Yak Peak. Please continue to post your observations and photos to the Mountain Information Network. It helps strengthen our data gathering.

Up to 10 cm of new snow has fallen into the region since Friday. Ongoing southerly winds have scoured south-facing and east-facing slopes. Evidence of cross-loading is also found on any open slopes. Wet and heavy snow is found up to 1500 m. As freezing levels fall, a new crust will form up to 1500 m.

In sheltered terrain, around 30 to 70 cm overlies a rain crust that formed in late December. The mid-snowpack is well-settled. The lower snowpack consists of several crusts with weak faceted crystals above and below that are beginning to heal and bond to each other.

Snowpack depths are roughly 145 to 185 cm at treeline and taper rapidly below 1500 m.

A series of weak frontal bands will generate periods of light snowfalls Sunday night and Monday night. Overcast skies and dry conditions are expected Tuesday and Wednesday.

Sunday night

Cloudy, isolated flurries 2 cm, southwest winds increasing to 50 km/h, freezing levels around 1200 m, low of -4C at treeline.

Monday

Cloudy, lingering flurries 2-5 cm during the day, 5 cm overnight, moderate southerly winds gusting to 50 km/h, freezing level around 1000 m, high of -3C at treeline.

Tuesday

Mainly cloudy, no precipitation, moderate southeasterly winds, freezing levels around 1500 m, high of -2C at treeline.

Wednesday

Mix of sun and clouds, no precipitation, moderate southeasterly winds, freezing levels around 1000 m, high of -4C at treeline.

• Remember that the snowpack will be significantly different at higher elevations than lower down.
• Be especially cautious as you transition into wind affected terrain.
• Watch for areas of hard wind slab on alpine features.
• Closely monitor how the new snow is bonding to the crust.
