crusts, collapse failure above 8500’-9000’ may produce larger, more dangerous

When you’re out today, jump in steep test slopes, drop cornices, and anticipate shooting cracks in the new snow. With unusual winds out of the east to southeast, be more cautious as the drifting patterns will be different than what you may be accustomed to. For those without good snow assessment skills, I’d recommend staying on slopes less than 35 degrees, where the danger is less pronounced.

A cold Pacific storm system will continue to produce snow throughout the day with another 5-8” expected in favored areas. With the upper Low pressure system movingoverhead, it’s difficult to forecast the wind direction and speed (not to mention snow amounts), but I’d guess that winds will rotate south averaging 15-25mph. Temps will remain in the upper single digits to low teens. A ridge builds in for the early part of the week.
