With the continuing spring snowstorm, the avalanche danger in the region has elevated to considerable, due to what forecasters term “upside-down conditions.” With temperatures expected to warm, the new snow will be higher in density, heavier than the light snow below it.
This creates an “upside down” snowpack, making avalanches more likely to trigger as the new snow falls. New snow amounts over the last 48 hours range from 12-24”. Winds have come from a wide variety of directions during this storm.
As a result it will be possible to encounter loading in unusual spots. Slab depths will range from 1 to 3 feet. Involvement in an avalanche today would have serious consequences due to the potential high volume of snow.
Use a conservative approach to terrain by avoiding steep wind loaded slopes. In steep wind loaded terrain it will be important to be on the lookout for obvious signs of unstable snow such as avalanches, shooting cracks and whoompfing.
In the low elevations the danger will be Moderate, where it will be possible to trigger shallow avalanches in very steep terrain in areas that had snow on the ground prior to this recent storm.
