What happened

The episode as NWS AFG wrote it up.

An area of low pressure dropped out of the high Arctic and deepened to 998 mb just off the coast of Banks Island. The low combined with a strong ridge of high pressure that extended from northern Russia and into the Brooks Range to produce a very strong pressure gradient along the Beaufort Sea Coast. High winds combined with falling snow to produce significant blowing and drifting snow and blizzard conditions.

Zone 203: Blizzard conditions were observed at Deadhorse from approximately 8 am on the morning of the 2nd through 2 am on the morning of the 3rd. A peak wind gust of 56 mph/49 kt was observed at the Deadhorse ASOS.

Zone 204: Blizzard conditions were observed at Barter Island from approximately 5 am on the morning of the 2nd through 5 am on the morning of the 3rd. The blizzard was more severe at Barter Island than it was further to the west along the central Beaufort Sea Coast. A peak wind gust of 71 mph/62kt was observed at the Barter Island AWSS. According to public accounts, there were minor power outages during the storm and the school was closed for two days. The drifting snow was likely significant as the school remained closed the day after the blizzard ended.
