Month’s worth of rain in 3 hours: Numbers define ferocity of Friday rainfall in New York

Friday's sudden flash floods in New York City took many by surprise. It was the one for the record books, when it rained, it just rained and rained.

The flash floods triggered by unprecedented rainfall shut down entire subway lines, turned major roadways into lakes and forced Gov. Kathy Hochul to declare a state of emergency. Ms. Hochul called it a “life-threatening rainfall event,” and Mayor Eric Adams called the storm “something that we cannot take lightly and we are not taking lightly.”

Here are some of the records that Friday rain broke and some astounding amount of rain that shut the entire New York City.

Average rainfall in new York in the month of September is 4.3inches. But yesterday's numbers were far beyond-

However, Friday recorded wettest day in the history of New York City since 1948, with John F. Kennedy International Airport recording 8.5 inches of rain.

Hence, Friday's rain was double of average September rainfall in the area.

Central Park recorded its 6th wettest day on record since 1869 and wettest day since remnants of Hurricane Ida that flooded the city two years ago. Nearly 2 inches of rain fell in one hour in Central Park making it second-wettest hour there in 80 years. More than 5 inches of rain have fell there till evening.

A month’s worth of rain, up to 4.5 inches, fell in only 3 hours on Friday morning in Brooklyn, with total number going up to 7.32 inches.
