An anomalous low pressure system over southeast New York produced numerous thunderstorms with torrential rainfall which led to flash flooding in portions of New York City, Long Island and the Lower Hudson Valley. The torrential rainfall caused a sewer to collapse producing a 6 ft. deep sinkhole outside of FDNY ladder company 24 on W. 31st Street in Manhattan.
