The first half of the day stayed quiet for some and jolted others, with a quick line of powerful storms dumping an inch of water in parts of New Jersey by 8 a.m. As the day wore on, widespread showers fell elsewhere, with flash floods leaving more than 5 inches of rain, according to radar estimates, in parts of New Jersey's Bergen and New York's Westchester counties by the early afternoon. In the area around Purchase and Mount Pleasant, in Westchester County, up to nine inches of rain may have fallen, radar showed.
Several roads had to be closed and high water rescues were said to be underway. New Jersey's Bergen County had a slew of road closures due to streets being inundated by the rain, some where vehicles were almost entirely submerged and people had to ditch their cars, climbing out of the windows to escape. In the city, the rain led to a massive sinkhole opening up on Radcliffe Avenue in the Morris Park neighborhood, making the road impassable. Some time later, a white work van was swallowed by the expanding hole.
Mass transit options were also impacted by the rain, including in the city, where A trains were were not running between 168th Street and Inwood-207th Street in the Bronx for some time, while crews worked to remove water from the tracks near Dyckman Street. C trains were also impacted by the flooding. Video from inside an MTA bus in the Bronx showed water pouring in from the rear door with riders on board, as the street had flooded.
The Pascack Valley Line, as well as the Morris and Essex Line, for NJ Transit reported delays of at least 30 minutes. On Metro-North, delays of up to 70 minutes were reported on the New Haven and Harlem lines at Grand Central after a flooding condition in the Bronx.
A record amount of rain fell at Central Park throughout the day on Monday, with 1.85 inches recorded — breaking the daily rainfall record of 1.76 inches previously set in 2012.
