Sunday rain in New York City breaks records


Doppler-estimated rainfall over northern New Jersey, southeast New York, Long Island and southern Connecticut Sunday.
New York’s Kennedy airport received 7.8” of rain Sunday, its soggiest day since records began in 1948. Its single-day rainfall output was about twice its average monthly total.

Extreme southeast New York and a large section of central and northern New Jersey experienced the deluge with rainfall totals of 2 to 8 inches common. Central Park received 5.81”, its fifth wettest day on record. In Newark, 6.4” fell, its second greatest single-day rainfall total.

As much as 10 inches of rain was recorded on Long Island according to the National Weather Service.

The New York Daily News reported widespread flooding from the deluge:

The heavy rain caused scattered power outages and transit disruptions. Cars got caught in flash floods, and the Long Island Rail Road reported localized flooding and trees on the tracks, delaying several dozen trains and closing the Far Rockaway and Long Beach branches.

In the subways, water flooded into tunnels, knocking out parts of seven lines in the morning.

The extreme rainfall arose from a slow moving area of upper level low pressure, which allowed thunderstorms to develop and redevelop over the same areas. AccuWeather said: “The excessive rainfall amounts in the Northeast with this storm are more on par with the rain from a tropical storm or a hurricane.”

Philadelphia also received heavy rain, tallying 4.84” - a daily record. And flooding was reported there, according to the Philadelphina Inquirer.
