Winuba (Mount Tom) - Wet Snow in the Alpine
Went up and over Winuba (Mount Tom) today from Pine Creek to the east headwall. We wanted look at transitioning snow above 12,000′ and assess wet loose conditions.
- In the afternoon surface snow was wet on steep south through northeast faces up to 13500′.
- Northeast facing snow in the alpine has yet to consolidate and it is prone to wet loose avalanching.
- By 12:30 PM it was easy to trigger wet loose avalanches up to size 1 on NE aspects steeper than 45 degrees.
- West and northwest facing aspects have been wind-hardened and present strong surface snow. Below 11,0000′ west aspects are transitioning to melt-forms.
- Steep north facing snow above 11500′ is still soft. It saw some warming by air temperature in the early afternoon, but moist daytime snow is “drying out” (recrytsallizing) overnight.
