In sintesi

Today the avalanche danger is CONSIDERABLE on steep, upper elevation slopes that have recent deposits of wind drifted snow. Avoid slopes with a smooth rounded appearance or that show signs of instability such as cracking in the snow surface. There also remains an isolated, or MODERATE danger for avalanches stepping down 2'-4' deep into buried, persistent weak layers of loose, sugary, faceted snow. Northerly facing slopes with steep, rocky, and more radical terrain are the most suspect for this type of avalanche.

    With winds on the increase and plenty of loose snow available for transport, avalanches involving wind drifted snow will be your primary concern today. Be on the lookout for fresh deposits and newly formed stiff slabs, on the lee sides of ridge crests and terrain features in upper elevation, wind exposed terrain. Avoid slopes with a smooth rounded appearance or that show signs of instability such as cracking in the snow surface.

    With our poor snowpack structure, the possibility remains for triggering an avalanche on a buried persistent weak layer of loose, sugary, faceted snow. This is primarily a low probability, but high consequence situation where a triggered avalanches could release between 2'-4' deep. The danger is most acute in areas of steep, rocky, north facing terrain that has a weak, sugary, underlying snowpack, and I'm going to continue to avoid those areas.

Snow and Weather

Happy New Year! We are off to a great start with our season, let's keep it coming!The mountains picked up about 6" of low density snow yesterday but the story this morning is the wind. Increasing overnight from the ESE, winds have now switched to the dreaded NE, and are blowing in the 20's with gusts into the 30's. And it's cold. Temperatures are in the single digits at 10,000', and right at zero on Pre Laurel Peak. Moderate easterly winds will continue today with wind chill values as low as -20. A couple more inches of snow are possible before the system exits the area. The rest of the week brings drying conditions and warmer temperatures with another system out there for the weekend.

Reports of good powder skiing came in from yesterday. Today you will need to stick to more sheltered terrain. Dave Garcia was out and about and sent in this observation.
