Rainfall rates exceeding 25 mm/hr will occur with the heaviest cells this afternoon and evening. Totals upwards of 75 mm will occur on south-facing slopes of the central mountains with 50-75 mm in cities like Kyoto and Nagoya. The Tokyo metro will see moderate to heavy rainfall with amounts 25-50 mm leading to localized flooding. The heaviest rainfall should gradually taper off overnight tonight into early Monday.
