NEW YORK – The largest mass transit system in the country was swamped by flash flooding as water poured into New York City's subway system and Grand Central Terminal, causing a travel nightmare for commuters Thursday.
The messy commute across the Big Apple and much of the Northeast and mid-Atlantic was brought on by heavy rain from severe thunderstorms, which prompted New York Governor Kathy Hochul to declare a State of Emergency.

New York City subway riders climb fence to avoid floodwaters
New York City subway riders climbed a fence to avoid floodwaters that had poured into the 7th Avenue station in Brooklyn after torrential rain Thursday.
Brooklyn's Prospect Park recorded 2.49 inches of rain Thursday. Bayside, Queens recorded 6.35 inches.
The Long Island Railroad, which stops at Grand Central, was partially suspended due to flooding. Video out of Queens showed firefighters assisting some passengers out of a train that was halted due to the severe weather.
The Metropolitan Transportation Authority (MTA) said it suspended traffic in both directions on the Port Washington Branch due to flooding east of Flushing Main Street.
Delays spilled into Friday morning as crews worked to repair damage caused by Thursday's storm, the MTA said.
The MTA says it served roughly 3.4 million riders daily in 2024.
