Light to moderate are now also affecting most of Shikoku and Honshu with rain bands extending as far east as the Tokyo area. Rainfall amounts will range from 100-200mm with isolated amounts of possibly up to 400mm. Beware of flash floods and landslides as Ma-On moves across Japan tonight into tomorrow.

Forecasts are showing Ma-On making landfall in the Southeastern section of Kochi moving northeastward across Tokushima later tonight (Japan Time). It will then move across Wakayama prefecture, about 80km south of Osaka by Wednesday morning. It will also weaken to a tropical storm by that time. It will continue moving southeastward remaining south of Nagoya and by Thursday morning it is forecast to be around 250km south of Tokyo. Still moderate rains will linger in the country along with breezy conditions until Thursday. Ma-On will then move northeastward by Friday well away from Honshu as it begins its extra tropical transition.
