Weather Forecast
Wednesday morning will start out cold at -18c and expected to warm up to -4c. Skies will be a mix of sun and cloud, along with light westerly winds. The forecast snow by Wednesday afternoon is a whopping 2cm.
Avalanche Summary
One size 3 natural on a NE aspects near Galatea creek that started around 2700m. This occurred sometime Tuesday morning.
Snowpack Summary
We still have a winter snow pack with widespread wind slabs dominating the alpine and open areas at treeline. Soft slabs can be found when you transition into tree line. The midpack remains strong while the basal facets are weak. Isolated sun crust can be found on solar aspects. If the sun comes out, solar aspect slopes can become a concern.
Terrain and Travel
- Avoid shallow snowpack areas, rock outcroppings and steep convex terrain where triggering is most likely.
- Caution around slopes that are exposed to cornices overhead.
- Minimize exposure to sun-exposed slopes when the solar radiation is strong.
Problems
