WESTERN WYOMING AVALANCHE ADVISORY
Issued on Fri February 12, 2016 6:18 PM
Spring-like conditions remained over Western Wyoming on Friday. Skies were clear, and mountain temperatures warmed into the mid to upper 30s. Valley highs were near 40. Southwesterly to westerly ridgetop winds ranged from 10 to 20 miles per hour.
On sunlit aspects, sun crusts broke down and snow surfaces became wet in the afternoon. Dry, settled powder can still be found in north facing terrain. Repeated warming and cooling cycles have strengthened and consolidated the snowpack. In the shallow snowpack of the Togwotee Pass region, persistent weak layers continue to be a concern.
FORECAST FOR Saturday, February 13, 2016
Pacific moisture will bring some cloud cover overnight and during the day on Saturday. A few flurries may be possible in the afternoon. Overnight lows in the mountains will be in the low 20s before rising to near freezing during the day. Westerly ridgetop winds will range from 15 to 25 miles per hour.
On Saturday in the Tetons and Greys River area, the general avalanche hazard is expected to be Low in the morning and could rise to Moderate in the afternoon. In very steep, wind-loaded terrain that has not gone through melt-freeze cycles, skiers and riders might be able to trigger an isolated pocket of wind slab. If periods of sunshine occur during the day, the threat of wet slides could return as the day warms. Persistent weak layers will keep the hazard at Moderate in Togwotee Pass forecast zone. There, backcountry travelers could trigger slabs one to three feet deep.
TREND FOR Sunday, February 14, 2016 AND Monday, February 15, 2016
The chance for new snow will increase on Sunday, and periods of light snowfall could continue into the week. The general avalanche hazard is not expected to increase until the next significant loading or warming event occurs.
