Cariboos Avalanche Forecast
Jan 15th, 2020 5:00PM
Stay warm, navigate around wind slabs, and be cautious of steep open slopes around treeline.
WEDNESDAY NIGHT: 5-10 cm of low density snow, strong wind from the south, alpine temperatures around -25 C.
THURSDAY: Cloudy with light flurries, moderate to strong wind from the southwest, alpine high temperatures around -18 C.
FRIDAY: Light flurries with mix of sun and cloud, light wind from the southwest, alpine high temperatures around -15 C.
SATURDAY: Light flurries with up to 5 cm of snow, moderate wind from the south, alpine high temperatures around -12 C.
Avalanche activity has quieted down over past few days, but incoming weather on Thursday will refresh the wind slab problem. Last weekend there were notable signs of a reactive persistent slab problem including large whumpfs and a large snowmobile triggered avalanche in the neighbouring Clemina area (see the MIN report). The surface hoar layer responsible for this problem has been harder to find since then, but could still potentially produce large avalanches in certain sheltered slopes around treeline and could perhaps re-activate with a sudden change in weather.
Surface conditions are variable due to cold temperatures and shifting wind directions over the past few days. The main concern over the past week has been a layer of surface hoar buried 60-120 cm beneath the surface, but recent observations suggest this layer has trended towards being less reactive under the current conditions.
Terrain and Travel
- Be carefull around freshly wind loaded features.
- Approach steep open slopes at and below treeline cautiously, buried surface hoar may exist.
Moderate flurries and strong southwest wind will form fresh wind slabs in open terrain on Thursday, especially near ridgetops.
Aspects:North, North East, East, South East, South, North West.
A layer of surface hoar buried 60-120 cm below the surface could still be reactive to human triggering in clearings around treeline.
Elevations:Treeline, Below Treeline.
