A broad swath of the Japanese archipelago, including eastern Japan, can expect torrential downpours as approaching powerful Typhoon No. 14 stimulates a seasonal rain front stretching in the south of the country, the Japan Meteorological Agency warned Oct. 7.

The typhoon is currently moving west-northwest and is forecast to brush close to the Daitojima islands, which lie to the east of the main island of Okinawa Prefecture, on Oct. 8.

It is then projected to change its course to northward, bringing storm conditions to Amami-Oshima island in Kagoshima Prefecture as well as inland areas of western Japan.

The typhoon’s journey northward is expected to trigger heavy downpours across extensive areas as the autumnal rain front remaining in the south of Japan becomes more active with increased vapor, the agency said.

As of 3 p.m. on Oct. 7, Typhoon No. 14 had an atmospheric pressure of 970 hectopascals at its center. It was generating maximum sustained winds of 126 kph near its center and peak instantaneous winds of 180 kph.

Although the typhoon is forecast to head eastward after going northward, the agency said its course may change due to a high pressure system spanning mainland China and the Pacific.
