‘Once-in-50-years’ rainfall event hits Nagasaki, Japan


Torrential rain struck the southwestern prefecture of Nagasaki in Japan, on Thursday morning, June 25, 2020– an event described by the national meteorological agency as 'once-in-50-years.' Rainfall in Sasebo also hit a record high for the month of June, with 281.5 mm (11 inches) recorded in a 24-hour period.

The Japan Meteorological Agency (JMA) said damp air was moving towards the rain front, producing unstable atmospheric conditions and brining rain clouds over the northern Kyushu area.

Sasebo City initially registered 181 mm (7.1 inches) in a three-hour period to 09:50 UTC (06:50 LT) on Thursday morning, which was already a record for the city. 

By 12:00 UTC (09:00 LT), the 24-hour rainfall in the city reached 281.5 mm (11 inches) –another record high for the month of June.

Nagasaki, in particular, was receiving levels of rain "seen only in about once in 50 years," said JMA.

Officials have issued evacuation orders to citizens in the central and northern parts of Sasebo due to a high risk of flooding.

JMA warned that extremely heavy rain with localized thunderstorms may hit northern Kyushu through Friday, June 26, with up to 180 mm (7 inches) expected in northern Kyushu and 100 mm (3.9 inches) in Chugoku.

More than 30 mm (1.2 inches) of rain is forecast in wide areas from the Hokuriku region to eastern Japan.
