Psyringe: From what I heard of others, the people who do have power (either through access to the power net, or through a working generator) are often very generous, and let others charge their mobiles.
That is very comforting to hear since these people don't have phones to call for help and charging their cellphones definitely will go a long way to keeping them safe. The trauma of facing those floods and being cut off from civilization can definitely be made worse if they can't at least communicate with family, so this is good to hear.
With anything in this scale, especially the people who had to stay in their homes uncertain of making it through the night, the children would definitely be profoundly affected. Are there any emergency response systems for preventing/treating PTSD in victims of traumatic events? I assume it would be much cheaper for society to help these kids now rather than 10 or 20 years down the line. :/
