Red Flags Comments
Rapid warming: Temperatures forecast to hit 49 degrees at 9000 feet today, with SLC hitting 69. Doubtful that lower BCC, LCC and Mill Creek had refreeze, and with many folks hiking from the lower trailheads, caution may be advised when traveling under any potential slide paths, regardless of their overall size. Wet Slab potential is Likely in these lower elevations areas.
