WESTERN WYOMING AVALANCHE ADVISORY
Issued on Fri November 16, 2018 6:14 PM
Skies were mostly cloudy to overcast above Western Wyoming on Friday. Mountain temperatures remained in the low 20s as the valleys climbed into the low 40s. Southwesterly to westerly ridgetop winds ranged from 10 to 20 miles per hour in most areas. Mount Coffin, in the Southwest trails forecast zone, was the exception with wind speeds climbing into the 30s out of the northwest.
There is a mixed bag of snow surfaces in the mountains. Firm wind pack can be found at the highest elevations on wind exposed slopes, and sun crusts reside on sunlit aspects. Surface hoar and dry snow in the early stages of faceting are common in terrain that is sheltered from both the sun and the wind.
FORECAST FOR Saturday, November 17, 2018
A cold front dropping down from the north will bring light snow to the region overnight before tapering off in the morning. Overnight lows in the mountains will be in the mid-teens before rising to near 20 during the day. Westerly ridgetop winds will veer to the north at 5 to 15 miles per hour.
The general avalanche hazard is expected to be Low on Saturday above 8,500 feet. With light winds overnight and modest snowfall, avalanche activity will remain unlikely. Below 8,500 feet, snow depths are insufficient for avalanche activity.
TREND FOR Sunday, November 18, 2018 AND Monday, November 19, 2018
High pressure will develop on Sunday and remain over the region through the beginning of the week. The general avalanche hazard is not expected to significantly change.
