Salt River and Wyoming Ranges

The storm system that moved through western Wyoming yesterday only brought a couple of inches of new snow to the Southwest Trails/Gryes River forecast area. Snow depths remain quite shallow and avalanches are unlikely.

( Discussion is generated from the previous day's afternoon forecast. )A high pressure ridge will begin to build over the region behind this departing storm system. Lingering snow showers could bring another inch of snow as the atmosphere slowly dries out and cloud cover decreases on Friday. Some fog is possible in the valleys during the morning hours. Temperatures should drop into the single digits overnight and rise into the 20s in the mountains and the 30s in the valleys during the day. Winds will be light at 5 to 15 miles per hour and rotate around to the east or south. At the upper elevations isolated pockets of soft slab less than a foot in depth and loose snow sloughs could be human triggered in steep terrain where the new snow lies upon slick old snow surfaces. Avalanches are not a concern in areas where the new snow accumulated on bare ground. The general avalanche is expected to be LOW at the upper elevations. Small slides in steep terrain can cause serious injury, especially during early season conditions when rocks and other obstacles increase the potential for traumatic injury. No hazard is anticipated at the mid and lower elevations.
