Winter Storm in Glacier Bay, Alaska

Winter Storm March 12, 2017 – March 13, 2017 · Glacier Bay, Alaska

What the National Weather Service wrote

Gustavus got 5.6 inches of new snow by 0800 3/13 and by 200 the storm total was 8.6 with more light snow after that.

The wider storm

On 3/12 the arctic front was over the central Panhandle as another in a series of storms moved northward from off the Pacific Northwest. By the afternoon of 3/12 the storm center had deepened to 981 MB off Dixon Entrance forcing warm moist air over the arctic air in place. The result was heavy snow for most of the Panhandle into 3/13 and lingering snow into 3/14. The impact was intense snow removal for storm totals up to 20 inches on top of an already deep snowpack. This was a setup for avalanches later that week.
