WESTERN WYOMING AVALANCHE ADIVSORY
Issued on Fri April 18, 2014 6:47 PM
The day began with mostly cloudy skies and mild overnight temperatures. Moisture in a southerly flow ahead of an approaching cold front fell in the form of one to five inches of new snow at the higher elevations and rain showers at the mid and lower elevations. The front quickly passed to the east and skies were mostly clear by 6 PM. Temperatures were in the low 30s to upper 20s at the higher elevations, in the 30s to 40s at the mid elevations and in the 40s in the valleys. Winds were south-southwest at 15 to 30 with gusts to 40 miles per hour and veering towards the west-southwest later in the day.
At the highest elevations strong southwest winds formed small, isolated pockets of shallow wind slab on firm old snow surfaces. Rain and above freezing temperatures dampened snow surfaces below an elevation of 9,000 feet.
FORECAST FOR Saturday, April 19, 2014
A mild westerly flow will bring mostly dry conditions to the region. Skies will be clear overnight with temperatures that are expected to drop into the 20s by dawn. Skies will be mostly sunny on Saturday with temperatures rising into the 40s and 50s. Winds will be west-southwest at 5 to 15 miles per hour.
At the highest elevations small pockets of shallow wind slab formed by southwest winds may be found in isolated areas and could pose a hazard to extreme skiers and climbers. Warming temperatures and sunshine could create shallow new snow sluffs and will increase the potential for wet slides to occur in very steep terrain and cliff areas after significant softening of the snow surfaces occurs. The general avalanche hazard will be LOW in the morning and increase to MODERATE during the day.
TREND FOR Sunday, April 20, 2014 AND Monday, April 21, 2014
Mostly dry conditions are expected through Monday. The general avalanche hazard will be low in the morning and increase after snow surfaces soften.
