Fear of linear precipitation zone in Kyushu, Japan Meteorological Agency predicts the first occurrence


 The Japan Meteorological Agency announced on the 15th that a "linear precipitation zone" that causes heavy rainfall in a short time from the night of the same day to the morning of the 16th may occur in the southern part of Kyushu (excluding the Amami region) and the northern part. On the 16th, there is a risk of heavy rain nationwide due to the effects of low pressure and fronts, and the Japan Meteorological Agency is calling for strict caution against sediment-related disasters and river flooding.

The forecast for the occurrence of the linear precipitation zone began operation in June this year, and this is the first time that it has been announced. According to the Japan Meteorological Agency, there is a limit to the accuracy of prediction, and the current hit rate is about 50%, but "even if it does not occur as a result, it may be a very dangerous situation."

Heavy rainfall occurred mainly in Kyushu on the 15th, and the 24-hour precipitation until 6 pm was 231.5 mm in Ebino City, Miyazaki Prefecture, 214 mm in Hitoyoshi City, Kumamoto Prefecture, and 131.5 mm in Kirishima City, Kagoshima Prefecture. Ebino City and Kobayashi City, Miyazaki Prefecture, recorded the highest hourly precipitation of 94 mm and 80.5 mm, respectively, in the history of observation.

 The expected 24-hour precipitation by 6 pm on the 16th is 250 mm in Kyushu, Shikoku, Kinki, 150 mm in Tohoku, 120 mm in Tokai, Amami, China, Hokuriku, 100 mm in Kanto Koshin, and 80 mm in Hokkaido.

 It is expected that there will be heavy rains in eastern and northern Japan on the 17th.
