Powerful Typhoon Prapiroon was moving northeast above the Sea of Japan on July 4 before it is expected to be downgraded to an extra-tropical cyclone by the evening, the Japan Meteorological Agency (JMA) said.

The JMA is once again warning of landslides, floods and swollen rivers through July 5.

As of 3 a.m. on July 4, the typhoon, this year's seventh, was located about 140 kilometers north-northwest of Hagi, Yamaguchi Prefecture, and was moving northeast at a speed of around 25 kilometers per hour. The atmospheric pressure at its center was 980 hectopascals and the typhoon was packing winds of 25 meters per second at its center. The maximum instantaneous wind speed was 35 meters per second.

There are high risks of landslides in some areas in Kyushu, Shikoku and Hokkaido because of heavy rains brought by the typhoon.

Warm and wet air is expected to blow toward the typhoon and the downgraded extra-tropical cyclone, bringing heavy rain and thunderstorms to areas in western and eastern Japan along the Pacific coast as well as northern Japan through July 5.

Moreover, warm and wet air will blow toward a low pressure system and a rain front on July 6, bringing heavy rain to wide areas in western to northern Japan.

The amount of rain over a 24-hour period up to 6 a.m. on July 5 is estimated to be up to 300 millimeters in Shikoku, 250 millimeters in the Kinki and Tokai regions, 180 millimeters in the Kanto-Koshin region, 150 millimeters in the Hokuriku district and 100 millimeters in the Tohoku and Hokkaido areas.

The level of rain over a 24-hour period up to 6 a.m. on July 6 is forecasted to be up to 300 to 400 millimeters in the Tokai region, 200 to 300 millimeters in the Shikoku, Kinki, Hokuriku and Kanto-Koshin regions and 100 to 150 millimeters in the Tohoku and Hokkaido districts.
