Heavy Snow — Interior Seward Peninsula, Alaska

2025-11-17 to 2025-11-19 · Interior Seward Peninsula, Alaska

Event narrative

The Pilgrim Hot Springs SNOTEL site (PHSA2) located in the higher terrain of the southwestern Seward Peninsula experienced almost 48 hours of steady heavy snowfall. 8 inches of new snow was reported in the first 24 hours with a 48 hour total of 13 new snowfall.

Wider weather episode

A persistent upper trough lingered over the Bering Sea for several days during the middle part of November. As a result, a series of surface lows tracked north along the west coast of Alaska bringing periods of heavy snowfall and very strong winds, especially along the coast and over the northern Bering Sea and Bering Strait. Blizzard conditions resulted in some spots near the coast while very heavy snowfall occurred across higher terrain just inland.
