The culprit for this was a vigorous closed low in the Beaufort Sea northeast of Alaska's north coast, driving a powerful Arctic cold front southward through the state.

Strong winds around this Beaufort Sea storm prompted high surf advisories for the north coast of Alaska, where sea levels up to a feet above normal and minor local beach erosion was possible, according to the National Weather Service.
