Over the weekend North aspects saw some natural activity in the form of wet loose snow avalanches. Surface snow that had become weak during the long dry spell of mid to late March heated up for the first time from a combination of mild temps and cloud cover. While this activity is on the decline there is still a slight chance for this to occur. This is a potential issue that exists in isolated pockets, primarily on higher elevation North facing slopes. The surface snow on all other aspects is currently either damp or refrozen. A cooling trend in temps overnight have helped to solidify the surface snow. Today the mercury will climb back into the low 40s F at 1,000’. While this will weaken the snow on the surface, the effects will be minimal. Be on the lookout for very low volume wet loose avalanches on very steep lower elevation slopes in addition to steep North facing higher elevation terrain.
Cornices have grown mature throughout the season. Many higher elevation slopes have these giants looming above them. Warming temps combined with direct sunlight will help to destabilize these features. Keep your distance from cornices today. They are unpredictable and deserve your respect.
In the past 24 hours a trace of new snow has fallen above 2,000′. Ridge top temperatures averaged in the low to mid 20s F. The Center Ridge SNOTEL station at 1,880′ averaged in the low 30s F with a max reading of 41 degrees. Winds have been light with the Sunburst station averaging 5 mph out of the East, with a max gust of 18 mph.
Today expect cloudy skies with occasional clearing. Very light intermittent snow and rain showers can be expected with rain/snow line hovering around 1,000′. Winds will pick up into the 15-20 mph range out of the Northwest. Temperatures at 1,000′ will climb back up into the low 40s F.
A chance for continued light snow and rain will continue through Tuesday. By midweek a ridge of High pressure will develop over the area bringing with it sunshine and mild temperatures.
