WESTERN WYOMING AVALANCHE ADIVSORY
Issued on Wed April 23, 2014 7:46 PM
Moisture in the form of snow showers began to move into the region around midnight. Skies were cloudy with periods of snowfall in the morning and mostly cloudy with snow showers in the afternoon. In general the upper elevations received one to four inches of new snow, however the Chief Joseph station on the west slope of the Teton Range, at Grand Targhee Resort, received seven inches with 0.65 inches of moisture. Temperatures were in the teens and 20s in the mountains and in the 20s and 30s in the valleys. Winds were west to southwest at 15 to 25 miles per hour with higher gusts.
The new snow is falling on firm old snow surfaces. At the upper elevations westerly winds formed small pockets of soft slab on leeward aspects.
FORECAST FOR Thursday, April 24, 2014
Snow shower activity will decrease but continue overnight. On Thursday skies will be mostly cloudy with a mix or snow and rain showers. Temperatures will drop into the 20s tonight and warm into the 30s and 40s during the day. Winds will be west to southwest at 20 with gusts to 30 miles per hour.
The general avalanche hazard is expected to be LOW. At the upper elevations isolated pockets of wind slab up to 14 inches in depth could be human triggered in some steep wind loaded avalanche starting zones. These surface slabs could knock a person over and/or carry them down a very steep slope. Avalanches are unlikely at the mid and lower elevations.
TREND FOR Friday, April 25, 2014 AND Saturday, April 26, 2014
Conditions will continue to remain unsettled with a warming trend and a mix of rain and snow showers. At the higher elevations pockets of wind slab will continue to be a hazard in very steep terrain and cliff areas.
