New York underwater.
There has never been such a weather in New York City. The New York City National Weather Service announced Wednesday evening – early Friday morning CET – that this was the first time a flood emergency warning should be issued. During the night, Central Park experienced the most rain that fell in an hour.
The so-called flash flood emergency advises people to go to higher ground immediately and thus avoid walking or driving during the flood.
