The episode as NWS AFC wrote it up.
An active front moved into the Bering Sea coast on the morning of March 9th. This produced blizzard conditions in the northern portions of the Bristol Bay zone beginning Tuesday morning. This front also result in amplifying the pressure gradient over south central Alaska resulting in strong east to southeast wind through Portage pass and along Turnagain Arm and the Anchorage Hillside. This strong east to southeast flow was responsible for pushing moisture into the Alaska Range that resulted in heavy snowfall beginning late Monday night and continuing through Tuesday evening. Two feet of snow fell overnight Tuesday into Wednesday morning. Additional snowfall reports ranged from 6 inches to 10 inches in addition to the two feet reported at Shell Lake.
