Tomorrow May be severely rainy locally West Japan and East Japan May 18, 12:02
Rain is intensifying mainly in Kyushu due to the influence of front lines and low pressure. Atmospheric conditions may become unstable in western Japan on the 19th and in eastern Japan on the night of the 18th to the 19th, causing extremely heavy local rain. The Japan Meteorological Agency is calling for caution in sediment-related disasters, inundation of low-lying land, and flooding of rivers.
According to the Japan Meteorological Agency, atmospheric conditions have become unstable due to the effects of warm and moist air flowing toward a tropical cyclone near Okinawa and a stagnation front near Kyushu.
A heavy rain cloud developed mainly in Kyushu, and we observed a heavy rain of 45 mm at Kagoshima Airport one hour before 11:00 am on the 18th.
In Kagoshima prefecture, the danger of sediment-related disasters has increased due to the rain so far, and there are areas where "sediment-related disaster warning information" has been announced.
Due to the stagnation of the front, 70 mm of rain per hour may be locally accompanied by lightning in the south of Kyushu over the night of the 18th, and in the western Japan over the 19th and in the eastern Japan between the 18th and 19th, it will be extremely rainy. Heavy rain is expected.
It is expected that the amount of rainfall in the 24 hours until the morning of 19th will
be 180 mm in
▽ Southern Kyushu, 150 mm in ▽ Shikoku and northern Kyushu
, and 120 mm in ▽ Tokai and Okinawa.
Furthermore, in the Tokai area, heavy rains may occur in various places, such as 50 to 100 millimeters of rain falling 24 hours after the morning of the 19th.
The Japan Meteorological Agency cautions against sediment-related disasters, inundation of low-lying land, and flooding of rivers, and calls for sufficient caution against gusts such as lightning strikes and tornadoes.
