Less snow than expected fell during the day yesterday, with drizzle up beyond 9000’. After midnight, temperatures began dropping dramatically as snowfall intensity increased. While many snow sensors are reporting light amounts of new snow, several reported up to 1.5” of water (especially around Mammoth and June), which could mean quite a lot more snow at higher elevations where snow was less dense. Yesterday, rain on snow was a concern for lower elevation slopes, but now that temperatures have dropped, these slopes which became quite moist yesterday will begin refreezing and stabilizing quickly. This will shrink the band of concern slightly for persistent weak loose buried layers, by bringing the lower elevation up a bit higher. Field tests yesterday at 8800’ showed that the upper snowpack was moist, but the lower buried facets were still loose and dry. As this upper snowpack refreezes, it will make it even harder to trigger the deeper facets, but they will still be there. At higher elevations, tests are still showing fractures to propagate in these deep weak layers, but consistently they are taking more and more force. With new snow-load, these layers will become a concern again until some time passes and the conditions settle, and they will become even less of a concern than before.
