Highlights

Wet slides will be the primary concern today. Overnight, cloud cover inhibited radiation cooling, mountain temperatures barely dipped below freezing and valley lows were above freezing. Skiers and riders might also be able to trigger a shallow pocket of dry soft slab in steep avalanche terrain at the higher elevations. This threat will be more pronounced above 10,500 feet, and daytime warming, along with any extended periods of sunshine, will make these slabs more susceptible to failure. Get an early start, monitor the breakdown of melt-freeze crusts, and transition to colder terrain or head back to the parking lot if conditions warrant. Roof slides are still happening. Grand Teton National Park has extended its bighorn sheep winter habitat closure on Mount Hunt and in the Prospector Mountain/Static Peak area from April 1 until April 30. Please respect these closures.

    Yesterday in Hoback Canyon, Cow of the Woods released naturally and put six feet of debris across the road. As the day warms, the likelihood for wet slides will be on the rise. Shallow wet loose sluffs involving the recent snowfall will be possible at the higher elevations. Lower down, in terrain where the snowpack is close to being isothermal, wet slides could gouge down to the ground, and possibly release as a wet slab. Any breaks in cloud cover will exacerbate this problem.

Avalanche Discussion

Skies will remain mostly cloudy to overcast tonight and through the day on Saturday, and the chance for light mountain snow/valley rain will continue. Overnight lows in the mountains will be in the mid-20s before climbing to near 30 in the afternoon. Valley temperatures will drop to near freezing tonight before climbing into the mid-40s during the day. Ridgetop winds will veer to the west at 10 to 20 miles per hour.On Saturday, avalanche conditions will be similar to those on Friday. In the mountains, stout crusts are not expected to form, and the threat of shallow wet slides could increase the hazard to Moderate in the afternoon if extended periods of sunshine occur. Skiers and riders might also be able to trigger an isolated pocket of shallow soft slab in high elevation, northerly starting zones. Snow surfaces are not expected to freeze overnight at the lower elevations, and the hazard will remain Moderate. Down there, wet slides could gouge down to the ground and possibly release as a wet slab. Get an early start, monitor the warmup and be willing to alter your travel plans if conditions warrant.
