General Advisory

GENERAL AVALANCHE ADVISORY Conditions are slightly cooler this morning with air temperatures reaching the freezing level down to an elevation of 7000-7500 feet. Wet loose avalanches are possible in the isothermal snowpack at low elevations this morning. As the day warms, the chances for such activity will increase as will the potential for slides at the higher elevations. Beware of steep slopes in areas where snow surfaces are wet and unconsolidated.

Situation

SITUATION Skies today were broken. Temperature rose particularly fast in areas hit by periods of direct sun. At 9000 feet, temperatures rose from the low thirties to temperatures ranging from the upper thirties to upper forties. Later this afternoon, some areas received a pulse of moisture that brought one to two inches of snow to the higher elevations. Winds varied from the southeast to southwest with ten to fifteen mile per hour averages. Air temperatures have been above the freezing point for over eight days. Settlement rates of approximately two inches per day continue as the dense snowpack further adjusts to the warm temperatures and melts at low elevations. Wet slides remain the concern in steep terrain at all elevations, although few were reported today.

FORECAST FOR Thursday, March 23, 2017 Moisture associated with a Pacific trough is to bring three to eight inches of snowfall to the upper elevations by Thursday night. Heaviest snowfall is to occur between 4am and noon Thursday. Temperatures are to be slightly cooler with highs at 9000 feet in the mid-thirties and valley temperatures reaching the mid-forties. Snow fall could briefly reach the valley floor during the morning. The general avalanche hazard will be Moderate. Wet slides will be possible in steep terrain at the low elevations in the early morning and will quickly become possible at all elevations as specific areas warm and the snow surface softens.

TREND FOR Friday, March 24, 2017 AND Saturday, March 25, 2017 Friday is to be dry and slightly warmer before another Pacific weather system brings a similar event on Saturday. The avalanche danger will not change significantly during this period.
