The Bering Sea west of Alaska hosted a whopping storm system over the weekend, with sustained winds equivalent to a Category 1 hurricane and gusts up to 115 mph. Having dropped 49 millibars between Saturday and Sunday, the incredible Aleutian cyclone constitutes a meteorological “bomb” — a storm that drops at least 24 millibars in 24 hours — more than twice over. Early Sunday morning, the storm’s central pressure finally bottomed out at 924 millibars, tying the record for lowest wintertime pressure in the North Pacific Ocean since records began in the winter of 1969-1970. The previous strongest storm in this region occurred just one year ago.
