Avalanche Forecast

Poor - Due to the number and quality of field observations

A strong Pacific storm is forecast to move into the region overnight and continue to produce moderate to heavy precipitation during the day on Thursday. Expect 15 30 mm of precipitation combined with strong southerly winds by Thursday evening. Friday should be a bit of a break between storms. Another warm, wet, and windy storm is forecast for Saturday. The models are disagreeing on how warm this storm will be, but they do agree that it will pack a lot of moisture. We should have a better idea of Saturday freezing levels by tomorrow.

No recent avalanches have been reported. I suspect that new storm slabs are bonding poorly in some areas and may be easy to trigger with light additional loads.

Below you can see a description of the "foundation" of the snowpack, everything is about to change with a series of snow and wind events forecast over the next few days. Forecast storm snow is likely to build slabs, which may bond poorly to the current surfaces including hard slabs, crusts, facets and surface hoar. The snowpack is highly variable across different aspects and elevations. There is anywhere from 30-150 cm on the ground. Previous northerly outflow winds scoured upwind slopes back to a firm crust, and created wind slabs on lee aspects, which are gradually gaining strength. Shallow snowpack areas are rotten (facetted).
