Don’t let the low or even no amount of new snow in town this morning fool you! This is a warm Atmospheric River storm, with snow lines wavering between 8000 and 8500’. Above this elevation it has been DUMPING all night, and it will continue to dump through most of today. The snow is being deposited much faster than it can adjust to hold its own weight, especially where it is being deposited even faster by the wind. The buried weak layers could very well come back alive. AVOID avalanche terrain today!
Snow sensors north of Mammoth on the eastern side of the mountains are indicating that lesser amounts of new snow have fallen than around Mammoth, but sensors deeper in the mountains are still showing high amounts. In areas where significantly less snow has fallen, avalanche danger may only be HIGH.
As snowfall tapers off this afternoon and evening, snowline will drop, but the timing isn’t certain. Could this mean 3” of snow down to 7000’, or a foot? We will see.
