(SOURCE)   The Bering Sea Superstorm has developed and is now weakening, but not after breaking a minimum pressure record held in the 1970s.

Partially derived from former Super Typhoon Nuri, the typhoon’s remnants joined up with the polar jet stream and a very strong disturbance in the mid-latitude belt of westerly winds, leading to explosive development of low pressure.

As a result, the Bering Sea storm whipped up hurricane-force winds in parts of Alaska’s Aleutian Islands as well as giant waves in the Bering Sea over the weekend.

On Saturday morning, U.S. time, the low was analyzed to have a pressure of 924 millibars, which makes it the strongest low-pressure system ever observed in or near Alaska since October 25, 1977, when a 925 millibar pressure reading was recorded on a ship docked at Dutch Harbor, Alaska. This system may also potentially be one of the lowest sea-level barometric pressures ever observed on Earth outside of tropical cyclones and tornadoes.
