Did you hear of evacuations down stream?
Not that I am aware of but you can watch the video linked below and judge for yourself. Today is the first time I came across this guy.
The guy says whatever forecast models he is referencing are calling for +1 meter of rain falling on and around Chengdu between this Wednesday and Friday.
Local water officials open floodgates on dams in the middle of the night. People go to bed everything is just raining, they wake up extra early to find their furniture floating around. If they have a second floor they go there. The evacuations happen after the water is flooding. They are not warned in advance. This is both upstream and downstream of the 3 gorges dam.
