Typhoon Nuri Poised to Become an Alaskan Super Storm; TD Vance Hits Mexico
By: Dr. Jeff Masters , 4:22 PM GMT on November 05, 2014
Typhoon Nuri is down to Category 1 strength as it steams to the northeast at 11 mph towards Alaska.Satellite loops show that Nuri has maintained a large area of heavy thunderstorms, but the eye is no longer visible, and high wind shear of 20 – 30 knots is significantly disrupting the storm. Nuri will lose its tropical characteristics on Thursday as it becomes embedded in a cold front. As the extratropical version of Nuri moves into the Bering Sea to the west of Alaska on Friday, a very powerful jet stream will interact with the storm and cause it to rapidly intensify into one of the strongest low pressure systems ever observed in the Pacific Ocean. Ex-Nuri’s central pressure is forecast to drop from around 970 mb late Thursday night to about 918 mb late Friday night. The 00Z Wednesday run of the European model predicted that ex-Nuri would bottom out near 918 mb at 03Z Saturday, about 300 miles west-northwest of the westernmost Aleutian Island, Attu. The 00Z Wednesday GFS model had the storm reaching 918 mb 300 miles north of Attu. The NWS in Anchorage is predicting that a large swath of hurricane force winds will be possible from Shemya eastward to Adak and Atka in the Aleutian Islands late Friday into Saturday, with seas building to 45 feet or higher. A storm surge of 2′ is predicted at St. Lawrence Island on Saturday morning, and over 1′ at Nome.
