Central Tokyo recorded its 34th consecutive day of rain on Tuesday, marking the longest such streak since Japan’s weather records began, according to the country’s weather agency.
Rain has fallen in the capital every day since Aug. 27. Approaching typhoons, a stationary autumn rain front and a low-pressure trough have contributed to the prolonged wet conditions, Kyodo News reported, citing the agency.
Rainfall exceeds monthly average
The previous record was 33 consecutive days of precipitation, recorded between June 27 and July 29, 2019.
The heaviest rainfall during the current streak was measured on Sept. 21, when central Tokyo received 156 millimetres of rain.
By Monday, total rainfall in central Tokyo had reached 629 millimetres — about three times the average precipitation for the entire month of September, Kyodo reported.
Wet weather expected to continue
Rain also affected large parts of eastern and western Japan on Tuesday. Echizen, in Fukui Prefecture in central Japan, recorded more than 30 millimetres of rain within an hour early in the morning.
The prolonged wet spell is not expected to end immediately. Rain is forecast to continue mainly across eastern Japan until around Thursday, partly because of the lingering autumn rain front.
Japan’s autumn rain front typically brings extended periods of unsettled weather as seasonal air masses interact over the country.
