Rain fell in parts of a US city and overwhelmed the sewer system, with officials reporting water entering at a rate of up to 6 inches per hour, far above the system’s design capacity of 1.75 inches per hour, according to the Guardian. Residents and commuters encountered knee-deep floodwaters, and flowing water moved at high speed in some locations. One video showed a woman alighting from a bus losing her footing and being pulled by the water. Major roads, including the Long Island Expressway, were blocked, and subway services were disrupted as water entered stations. Large amounts of mud and debris remained after the event, and videos captured bags of rubbish and loose litter being carried by the flowing water.
