Arthur Hits Nova Scotia, Becomes Post-Tropical; Cat 4 Typhoon Neoguri Forms

By: Dr. Jeff Masters, 3:23 PM GMT on July 05, 2014

Hurricane Arthur is no more. Its circulation has been absorbed by a trough of low pressure over the Canadian Maritime provinces after Arthur made landfall in Nova Scotia on Saturday morning near 10 am EDT as a tropical storm with 65 mph winds. On Friday night, Arthur skirted Nantucket and Cape Cod, Massachusetts, bringing a swath of 3 - 5" of rain across Southeast Massachusetts and Eastern Maine. Top winds at Nantucket were 50 mph, gusting to 59 mph, at 9:53 pm EDT.

Category 4 Typhoon Neoguri a threat to Japan
In the Western Pacific, Typhoon Neoguri has strengthened into a Category 4 storm with 135 mph winds this Saturday morning, and is headed northwest towards a Tuesday rendezvous with Okinawa in Japan's Ryukyu island chain. Satellite images show a huge and well-organized system, with a prominent eye, and very intense eyewall thunderstorms with cold cloud tops. WInd shear is light, 5 - 10 knots, and Neoguri is expected to be a Category 5 storm by Sunday. Neoguri will get caught by a trough of low pressure on Monday and begin curving to the northwest. The 00Z Saturday runs of our two top track models, the GFS and European models, showed Neoguri passing about 50 - 100 miles south of Okinawa near 00 UTC Tuesday, then curving to the north and hitting the Japanese island of Kyushu, where the city of Nagasaki lies, between 10 - 22 UTC on Wednesday. Neoguri is the 7th named storm and 3rd typhoon of the 2014 Western Pacific typhoon season. The other two typhoons of 2014--Typhoon Faxai and Typhoon Tapah--were both Category 1 storms. Neoguri is named after the Korean word for raccoon dog, and was also used for a 2002 typhoon that passed near Japan, and a 2008 typhoon that hit China.
