GNFAC Avalanche Advisory for Thu Mar 30, 2017
The current weather pattern will create a variety of avalanche problems today. On mid to low elevation slopes, above freezing temps and rain will increase the wet snow avalanche hazard.
Skiers outside of Cooke City triggered this small loose snow avalanche. With more snow on the way, similar slides are possible in steep terrain. Photo J. Holzer
