Typhoon No. 18 Very heavy rain in western Japan.
Typhoon No. 18 is moving northeast around the Korean peninsula, and there is a very heavy rain in western Japan due to the influence of moist air. The unstable atmosphere is expected to continue for three days, and the Japan Meteorological Agency is calling for caution against storms and heavy rains.
According to the Japan Meteorological Agency, Typhoon No. 18 is moving northeast around the Korean Peninsula and is expected to change to a temperate cyclone in the Sea of Japan on the evening of the 3rd.
Warm and moist air flows from the south toward the typhoon, which makes the atmospheric conditions unstable in a wide range of western Japan. In the 1 hour until 5:00 pm, all are rain gauges installed by the local government. In addition to observing 56 millimeters of heavy rain in Otsuki Town, Kochi Prefecture, we observed 32 millimeters of heavy rain in Shibushi City, Kagoshima Prefecture.
In western Japan, the atmosphere is expected to remain unstable over the 3rd, and there is a risk of very heavy rain with local lightning.
The amount of rain in 24 hours until the evening of the 3rd is expected to be 180 mm in Shikoku, 120 mm in the north of Kyushu, and 100 mm in the Chugoku region.
In northern Kyushu, there is a risk of a very strong wind centering on the sea from late night to early morning on the second day. The height is expected to be 5 meters.
In addition to storms and high waves, the Japan Meteorological Agency calls for caution in areas where heavy rain is expected, such as landslide disasters, low land inundation, and river flooding. Even in areas far from typhoons, caution must be exercised against tornadoes and other strong gusts and lightning.
