Forecast for Bridger-Teton National Forest Avalanche Center
National Weather Service Riverton WY
249 PM MST Tue Feb 21 2017


.DISCUSSION...The final round of snowfall is currently pushing
through far Western Wyoming at the moment as the associated
Pacific cold front slides southeast across the area. Expect a two
hour window of relatively heavy snowfall as the front pushes
through. The heaviest of the snowfall should be finishing up
around 5 pm late this afternoon north of Salt River Pass. The rain
has turned to snow at Alpine and will be changing over in Afton
shortly, so for the rest of this precipitation event, mainly
snowfall can be expected, even at the lower elevations to the
south. The heaviest of the snow should be dissipating in intensity
south of Salt River pass by around 7 pm this evening. The winter
storm warning for the Western Wyoming Mountains will continue
through 5 am Wednesday. Expect another 4 to 6 inches of snow to
fall in the mountains by Thursday morning and 1 to 3 inches in the
valleys. West winds will continue to gust between 40 and 50 mph on
the higher ridges and will only gradually decrease in speed
through tonight. On Wednesday, the gusts will diminish to 20 to 30
mph. Light snow is expected Wednesday through Friday as another
weather system delivers heavier snow to areas east of the
Continental Divide. Expect an increase in snowfall next weekend.
