General Advisory

NA

Situation

SITUATION For most of the day, Western Wyoming was under overcast skies as southwesterly flow aloft brought Pacific moisture and a weak disturbance through the region. By early evening, cloud cover began to decrease. Mountain temperatures rose into the mid to upper 20s as the valleys climbed to near 40. Southwesterly ridgetop winds veered to the northwest at 10 to 20 miles per hour. The weak disturbance brought two to four inches of new snow to the mountains of Western Wyoming before noon. Precipitation was in the form or rain or a rain/snow mix below 6,500 feet. Snowfall accumulated on supportable crusts that transitioned from over six inches thick at the higher elevations to a couple inches thick at 8,500 feet. During the day, the new snow remained dry above 9,500 feet. Below 7,000 to 7,500 feet, crusts were or became unsupportable to foot penetration by late afternoon.

FORECAST FOR Sunday, March 26, 2017 As a transitory ridge of high pressure moves into the region, flow aloft will veer to the northwest overnight, and skies will continue to clear with partly cloudy to mostly sunny skies present by Sunday morning. Overnight lows in the mountains will be in the teens before rising back into the upper 20s during the day. Valley temperatures will dip into the low 20s before sunrise and then rebound into the mid 40s in the afternoon. Westerly ridgetop winds will range from 10 to 20 miles per hour. The general avalanche hazard is expected to be LOW Sunday morning. With colder temperatures and partially to mostly clear skies overnight, snow surfaces should experience a hard freeze at all elevations, which will result in a mostly stable snowpack starting off on Sunday. As the day progresses, warming temperatures and sunshine will impact the new snow in the mountains, and very shallow wet loosing sluffing will be likely. Softening of frozen crusts will beginning in the valleys before climbing in elevation as the day warms, particularly on sunlit aspects. Seek out colder terrain when supportable crusts begin to break down to avoid wet loose slides involving the older snow.

TREND FOR Monday, March 27, 2017 AND Tuesday, March 28, 2017 The chance for new snow will return Sunday night, and periods of light mountain snow and valley rain will continue into Tuesday. Similar springtime avalanche conditions will remain.
