Ian Jackson,
Forecasts are calling for snow and wind with highest amounts expected in the northern and western areas! If this materializes we expect to see an incremental rise in the danger rating over the next few days
Summary
Weather Forecast
The drought is ending with a NW flow bringing increased winds and snow. We can expect alpine winds to increase to strong overnight Wednesday with light precip starting. Expecting 5-10 cm on Thursday, with an additional 5-10 cm Friday and Saturday. Highest amounts will be in northern and western areas. Freezing levels expected to reach ~ 1400m
Snowpack Summary
Up to 5 cm of new snow sits on a variety of surfaces: wind effect in exposed alpine/treeline areas, sun crusts on solar slopes, and a thin temperature crust below 1600m.The Jan 30th surface hoar/ sun crust interface exists 20-30 cm below the surface and hasn't produced avalanches recently. Shallow snowpack areas remain weak and faceted
Avalanche Summary
No new avalanche activity observed or reported.
Confidence
Timing, track, or intensity of incoming weather system is uncertain
Problems
Wind Slabs
Increasing winds and forecasted snow may create new windslabs in lee alpine terrain. These will be small at first, but may not bond well to the hard surfaces underneath.
Aspects: North East, East, South East, South.
Elevations: Alpine.
