Weather Forecast
More cloud development as a cold front pushes down from the NW should start to cool things by midday Tuesday and NW winds will continue. As the front passes midday Wednesday expect up to 5cm of snow followed by the winds shifting to the West and abating. Cooling temperatures, lingering clouds and trace amounts of snow through Thursday and Friday.
Snowpack Summary
15cm fell on the weekend and NE and NW winds have redistributed this into windslabs on treeline ridgecrests and more widespread locations in the alpine. Surface crusts can be expected on steep SE through SW slopes. The Mid-December layer that is down over 1m in most deep areas remains a concern in high shaded terrain presenting a shallow snowpack.
Avalanche Summary
A few minor windslabs have been observed in the alpine that were likely triggered by continued wind loading. Pin-wheeling and minor loose wet avalanches occurred with heating yesterday and today on steep S and very steep E slopes and this activity may continue Tuesday morning with strong solar and an alpine temperature inversion possible.
