Wider weather episode

A north to south oriented frontal boundary brought periods of heavy snow, avalanche conditions, lowered visibilities, high winds and strong surf from west to east over the course of several days as the front shifted slowly east and developed into a triple point low over the western Gulf. Strong upper level dynamics and a deep moisture fetch made this an impactful storm for southern Alaska.
