General Advisory

GENERAL AVALANCHE ADVISORY The snowpack is mostly stable and avalanches are unlikely. If skies remain clear and snow surfaces soften significantly human triggered wet slides could become a possibility on very steep sunlit slopes.

Situation

SITUATION A fast moving upper trough and associated cold front is moving into northwestern Wyoming. Skies were mostly sunny before noon and cloudy with mountain snow showers in the afternoon. Strong southwest winds were increasing ahead of this approaching front. Temperatures dropped into the 20s overnight. Daytime highs rose in the 20s and low 30s at the upper elevations, into the 30s at the mid elevations and into the 40s at the lower elevations. Snow surfaces softened at the mid and lower elevations and remained mostly hard and frozen at the upper elevations. Data from Snotel stations in the Upper Snake River Basin indicate the moisture content of our snowpack is 144% of normal. Snow depths above an elevation of 9,000 feet range from seven to eleven feet. Snow depths up to five feet and areas of bare ground exist at the lower elevations.

FORECAST FOR Wednesday, April 16, 2014 A passing cold front will bring snow showers to the region overnight with accumulations of an inch or two possible at the higher elevations. It will remain unsettled on Wednesday with decreasing chances of snow showers. Temperatures will drop into the teens and 20s overnight and rise into the 20s and 30s during the day. Winds will be northwesterly overnight at 25 miles per hour and back to the west and decrease to 10 miles per hour on Wednesday. The general avalanche hazard is expected to be LOW at all elevations. The snowpack is mostly stable and avalanches are unlikely. At the upper elevations isolated pockets of very shallow wind slab could be triggered in cliff areas by climbers and extreme skiers.

TREND FOR Thursday, April 17, 2014 AND Friday, April 18, 2014 Conditions will be dryer with partly cloudy skies and cool temperatures. The general avalanche hazard will increase when sunshine and warmer temperatures return.
