Conditions are about to change with the forecast snow starting Thursday night.
Avalanche danger will increase with snow load and wind.
Careful evaluation of slopes is a must, especially with such a weak base of facets.
Summary
Confidence
Moderate - Uncertainty is due to the timing, track, & intensity of the incoming weather system.
Weather Forecast
Snow on the way. Most weather models are indicating snow starting late Thursday night, anywhere from 25-60cm in the alpine by Saturday night. Temperatures for Friday and Saturday in the alpine will hover around -5c, then dropping on Sunday. Winds for this time period will be moderate from the South.
Avalanche Summary
No new avalanches were observed.
Snowpack Summary
Widespread wind slabs are present in the alpine from the strong westerly winds over the last four days. At tree line and below, the lower half of the snow pack is made up of facets inter mingled with crusts. This facet interface will most likely become reactive if we get the large amount of snow that is forecast. Be on the lookout for newly formed soft slabs at all elevations, either formed from the wind or the warmer temperatures. This week end will be a time to carefully evaluate slopes before adventuring onto them.
