The National Weather Service forecasts the storm to produce wind gusts to 75 to 85 mph and waves up to 15 feet in height parts of the Bering Sea, and a storm surge (rise in coastal waters) of one to three feet in southwest coastal Alaska Wednesday into early Thursday.
On Tuesday, the storm underwent “bombogenesis”, meaning its central pressure – an indicator of intensity (lower=stronger) – plummeted at least 24 millibars (mb) in 24 hours. On Monday night, its central pressure was estimated to be 983 mb. By Tuesday night, the central pressure was analyzed at 954 mb. As of this morning, the National Weather Service estimated its central pressure at below 948 mb (for comparison, Superstorm Sandy’s lowest pressure was around 940 mb). As the storm rapidly deepened Tuesday, it produced an 86 mph wind gust near Adak Station in the Central Aleutians according to reports from the National Weather Service office in Anchorage.
Current satellite imagery shows the storm’s comma head spanning much of the northern Pacific, with its tail or cold front extending from the eastern Aleutians into the central Pacific.
The storm is forecast to gradually weaken in the next 24-48 hours as it moves north and inland over eastern Russia.
This north Pacific “monster”, as the National Weather Service calls it, is not the only disaster going on. At the bottom of the satellite image, you can view category 5 Super Typhoon Haiyan in the bottom left portion of the screen, tracking towards central Philippines.
Interestingly, both storms “bombed” or rapidly intensified at roughly the same time.
