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
