Winds out of the South/Southwest upwards of 40 MPH have pounded the PAC Advisory area along with measurable snowfall almost daily over the last week. With all of this wind and snow, we have grown some deep wind slabs on NW, N, NE, and East aspects above 7,000 feet---travel in wind loaded Avalanche terrain is not recommended today. Below 7,000 feet, and on other aspects that were not loaded by the wind have Considerable hazard, and deserve careful evaluation and respect today...take the time to look for clues as to which way the wind has been loading the snow, and stay out from under, and off of terrain steeper than 30 degrees. Gullies and other terrain features may receive cross loading and abnormal loading patterns due to local terrain features.
Our local Ski Resort, Brundage is reporting 46 inches of new snow in the last 7 days at the base area at approximately 6,000 feet. All of this snow coming into our Advisory area so quickly has a hard time becoming cohesive with the existing snowpack which makes for tender soft slabs on all aspects. While not as deadly as hard slabs, these soft slabs definitely deserve respect. Stay away from slopes over 30 degrees where these soft slabs will be likely. Time will heal/bond the new snow to the old snow. Conservative decision making and travel are essential today!
