Snowpack Summary
Friday's warm temperatures and sunshine moistened surface snow on most aspects and elevations. Warm overnight temperatures will prevent it from refreezing into a solid crust. Below the surface, stormy weather over the beginning of this week brought about 50mm of precipitation to the North Shore Mountains, most of which fell as rain to the summits. In the Sky Pilot area, 30-40cm of snow likely fell above 1600m and was redistributed into wind slabs in lee terrain by recent southeast winds. Cornices also gained fragile new growth over the same time period. Below the wind effect, the new snow is now forming a good bond to the underlying crust. The mid and lower snowpack are well settled and strong.
