Any potentially reactive wind slabs are likely confined to more extreme terrain features. Stay warm and enjoy the great travel conditions.
Recent northerly wind has created thin wind slabs in exposed lee terrain. Lingering widespread wind slabs from last week are still present but likely unreactive.
Brrrr! Arctic air ushers in bitterly cold temperatures with no new snow in sight.
SATURDAY NIGHT: Overnight low temperature around -25 C, moderate to strong wind mainly out of the north, no snow expected.
SUNDAY: A few clouds, daytime high temperature around -20 C, moderate to strong north/northwest wind, no snow expected.
MONDAY: Scattered cloud cover, daytime high temperature around -25 C, light variable wind, no snow expected.
TUESDAY: A few clouds, daytime high temperature around -30 C, light variable wind, no snow expected.
This MIN does a great job of highlighting the lingering wind slab problem that exists in more extreme terrain. There are a few more great MINS that shed light on recent riding conditions too.
In wind sheltered locations you can find up to 10 cm of light snow that rests on top of unreactive slabs which are faceting away in the cold temperatures. In wind exposed terrain wind effect is extensive and vast fields of sastrugi can be found.
A buried weak layer of surface hoar may still be found around 90 cm deep. It was found around Log Cabin and also in Powder Valley (see here). Avalanche activity on this layer hasn't been reported since the first week of January and isn't expected to spike without a substantial snowfall or warming trend.
The lower snowpack is strong around White Pass but a thinner and weaker snowpack structure is expected inland, such as in the Wheaton Valley and the south Klondike.
