This comes in the wake of a surge of rainfall from the same system that struck Eastern China on Sunday and Monday. In many areas to the West of Taiwan over 50-60mm of rainfall was reported in a 24hr period leading to some localized flooding in the region. Good news is Tuesday there will be a break in this activity as the low races across the Japanese Isles.
