Summary
Weather Forecast
Today will be mostly cloudy with flurries. Moderate to strong S'ly winds will transport snow, loading lees. Temps should range from -6 to -12 Overnight the next system will arrive, with 4cm overnight and up to 20cm by Saturday morning. Freezing levels are expected to remain below 1500m. Strong SW winds are expected to increase through the storm.
Snowpack Summary
In most areas, ~30cm of light snow overlies settled snow from last weeks storm. Tests indicate that as the new snow settles into a slab it may be triggerable. In some alpine areas wind slabs have developed on lee features after mod-strong S-SW winds. Jan 4th interface down 60-100cm and remains a concern in less traveled areas.
Avalanche Summary
No new natural avalanches were observed yesterday. On Tuesday, size 2.5 avalanches occurred from south aspects at ~2300m below Avalanche Peak as well as off of Mt Smart. Crisp crowns up ~1m deep with wide propagations indicate that they likely failed on the Jan 4th and were likely triggered by cornice fall or solar release from the cliffs above.
