Situation

SITUATION Skies were clear today with temperature inversions under a large high pressure ridge. Temperatures at 10,500 feet warmed into the mid-30s today and dampened snow surfaces on south facing slopes. Winds were northwest at 10 to 15 miles per hour. Sunshine and warm days at the higher elevations continue the development of crust on sunlit aspects. Cool, clear nights continue the growth of surface hoar on shaded aspects.

FORECAST FOR Tuesday, December 12, 2017 Tuesday will be dry with valley inversions. Skies will be mostly clear above areas of morning valley fog. Temperatures will drop into the teens and single digits overnight and rise into the mid-30s during the day. Winds will be from the northwest at 10 to 15 miles per hour. No new avalanche activity has been reported for several days. At the upper elevations skiers or riders could trigger isolated pockets of shallow wind slab up to 18 inches deep and wet loose sloughs on very steep slopes. Avalanches are unlikely at the mid elevations. Very little snow exists at the lower elevations. The general avalanche hazard is expected to be LOW.

TREND FOR Wednesday, December 13, 2017 AND Thursday, December 14, 2017 Dry conditions will continue until the end of the week. Temperatures will be cooler. The general avalanche hazard will continue to slowly decrease.
