This loose, wet avalanche was observed in Beehive Basin on a west facing slope. As warm temperatures and strong solar input soften the snow surface, both natural and human triggered avalanches will become more likely. Photo GNFAC

At 1030 the snowpack was tenuously holding onto last nights cold. It was -2C, 10 cm under the surface. This will quickly turn to zeroC which means water can begin to percolate down and weaken the snow further. Tomorrow (Tue, March 31) will likely see wet loose avalanches as a result. Photo: GNFAC
