Two fronts in one country. The north is still flooding: more than 2,000 homes submerged, some districts having taken more than 50 cm of rain this week, and more than 1,000 households isolated, with Ninh Binh and Thanh Hoa hardest hit south of Hanoi. The south's cold-air-driven spell, which began Sep 17, runs to about Sep 21 to 24, putting 10 to 20 cm on Ho Chi Minh City with flash-flood and landslide risk over Lam Dong and Dong Nai. High exposure, thin coverage. (Handled with care.)
