Typhoon No. 27 moved northeast away from Japan on October 7 and is expected to become an extratropical cyclone, according to the Japan Meteorological Agency as reported by Nishi-Nippon Shimbun. At 6 PM on October 7 the storm was far east of Japan, moving northeast at 85 kilometres per hour, with a central pressure of 965 hectopascals, maximum winds of 30 metres per second and gusts of 45 metres per second, the agency said.

The agency said the sea off the Pacific coast of Tohoku would be rough, with swells, through before noon on October 8, and put expected wave heights there at 4 metres, urging caution over high waves. TBS NEWS DIG had reported on October 6 that high waves with swells required caution around the Ogasawara and Izu islands and on the Pacific side from western to northern Japan. [ 1 , 6 ]
According to the agency, the typhoon was steered northeast by winds around a high-pressure system extending over the Pacific, and typhoons 28 and 29 could follow a similar course. TBS NEWS DIG reported on the evening of October 6 that typhoon 27 was expected to move away from Japan over the sea to the east, and its later reports framed the outlook around the question of the three typhoons. [ 2 , 3 , 4 , 6 ]
On the weather ahead, TBS NEWS DIG reported that clear autumn conditions are expected from Hokkaido to Okinawa under a migrating autumn high-pressure system, with low precipitation probabilities, and that the fine weather is forecast to continue through the three-day weekend from October 10 to 12, Sports Day. It noted Tokyo had moved into its clear autumn season after prolonged rain, that southern Kyushu could see some rain, and advised checking the Japan Meteorological Agency's latest information on typhoon tracks and high tides.

Why it matters
Typhoon No. 27 no longer poses a direct threat to Japan, leaving rough seas off the Tohoku coast as the main remaining risk for shipping and coastal areas. A forecast of clear autumn weather over a three-day weekend affects travel and leisure plans nationwide, while the paths of typhoons 28 and 29 remain an open question.
