Water flowing downhill from a ramp?
I saw one video of water flowing down from a ramp about half a story high, into one of the tunnels. Didn't make much sense at all to me. If it was a flood, wouldn't the water have risen starting at street level and then entered the tunnel at its opening. Or was water being pushed up from the sewers and water mains? I didn't see any video showing 13 foot high currents coming down the streets of Lower Manhattan. I saw only the water barely lapping above the pavement at Battery Park.
I am not questioning the extent of the damage, but the video evidence paints a puzzling story of what actually happened!
