Yukon

Strong south winds and light snowfall may have formed isolated wind slabs on lee slopes.

Back off slopes if you see signs of instability like whumpfing or cracking snow beneath your feet.

Low

• We are uncertain due to a limited number of field observations.
• We are uncertain due to a highly variable snowpack.

No avalanche activity has been reported.

If you’re heading into the backcountry, please consider submitting a MIN report—observations are particularly limited this time of year.

Ongoing moderate to strong south winds continue to redistribute new snow, possibly forming isolated wind slabs in leeward terrain. A layer of surface hoar may persist beneath these slabs in isolated areas, roughly 30 to 60 cm deep. This layer appears most reactive on shaded, north-facing slopes, immediately below ridgetop features.

A variety of firm or crusty surfaces is likely on south-facing and lower-elevation terrain due to warming and solar input, as well as in exposed higher-elevation areas where wind scouring continues.

The lower snowpack remains weak and faceted, particularly in areas with a shallow overall snowpack.

• Avoid steep, rocky, and wind-affected areas where triggering slabs is more likely.
• Pay attention to the wind; once it starts to blow, sensitive wind slabs are likely to form.
• Use extra caution around cornices: they are large, fragile, and can trigger slabs on slopes below.
• Even brief periods of direct sun could produce natural avalanches.
