Weather Forecast

Cloudy with sunny periods and some convective flurries are in the forecast for Wednesday. A cooling trend is forecasted and the freezing levels should be near valley bottom through the end of the week,.

Snowpack Summary

Cooler temperatures forecasted for Wednesday should tighten up the lower elevation rain saturated snowpack. At upper elevations some windslabs exist on lee aspects. The midpack is generally well settled and strong.

Avalanche Summary

There is lots of evidence of loose wet avalanches from warm weather and rain over the past weekend. No avalanches have been observed or reported in past 24 hours.

Confidence

Forecast snowfall amounts are uncertain

Problems

Wind Slabs

Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
