You may find fresh wind slabs up high from new snow and strong southwest wind.
TUESDAY NIGHT: Cloudy with snowfall, accumulation 5 to 10 cm, moderate to strong southwest wind, alpine temperature -5 C, freezing level 1400 m.
WEDNESDAY: Cloudy with snowfall, accumulation 5 cm, light to moderate southwest wind, alpine temperature -4 C, freezing level 1500 m.
THURSDAY: Mix of sun and cloud with isolated flurries, light to moderate southwest wind, alpine temperature 1 C, freezing level 2400 m.
FRIDAY: Cloudy with rain switching to snow, accumulation 10 mm rain followed by 5 to 10 cm of snow, light to moderate southwest wind, alpine temperature 0 C, freezing level 2400 m dropping to 1700 m.
Explosives triggered small cornice chunks on northerly ridges on Monday. The chunks did not trigger slabs on the slopes below.
If you have any recent observations during your travels, we would greatly appreciate it if you posted a photo or any other information to the Mountain Information Network (MIN). Thanks!
New wind slabs may from with around 10 cm of new snow and strong southwest wind. A melt-freeze crust or moist surface snow is expect below around 1500 m. The remainder of the snowpack is consolidated and strong. The snowpack is rapidly melting below treeline.
Some more snow and strong southwest wind may form new wind slabs in lee terrain features. Use added caution when entering slopes adjacent to ridges.
- Be careful with wind-loaded pockets, especially near ridge crests.
- Expect conditions to change rapidly with aspect and elevation.
- Use small slopes without consequence to test the bond of the new snow.
Aspects: North, North East, East, North West.
Elevations: Alpine, Treeline.
