New York City saw flash flooding on Wednesday, as large parts of Brooklyn and Queens received about 2in (50mm) of rainfall in as little as 20 minutes. Officials said the deluge caused water to flow into the sewer system at a rate of up to 6in an hour, quickly overwhelming an aged network that was designed to accommodate just 1.75in an hour.
Residents and commuters found themselves wading knee-deep through flood water that flowed with dangerous speed in places. One video showed a woman alighting from a bus losing her footing and being dragged along by the torrent of water. Several major roads were blocked, including the Long Island Expressway, and subway services were disrupted as water spilled into stations. Large amounts of mud and other debris was left behind; videos showed bags of rubbish being swept down streets along with loose litter.
