CENTRAL AND SOUTHERN VIETNAM — THE NORTH-SOUTH SPLIT HOLDS, LOCALLY OVER 300 MM

The north stays dry while the centre and south stay wet: 90 to 170 mm and locally more than 300 mm from Hue to Da Nang and along the south-central coast, from the evening of Sep 21 through Sep 23, with the Bo and Huong rivers at alarm levels one to two. There is no East Sea tropical cyclone — the rain is convergence-zone driven, which is why it persists instead of passing. (Handled with care.)
