Widespread flash flooding pummeled the New York City metro area Friday as remnants of Tropical Storm Ophelia lashed the already heavily saturated region with several inches of rain in mere hours, grinding the nation's largest city to a halt and setting JFK Airport's all-time rain record in the process. 

All of New York City's five boroughs suffered flooded streets and subway stations, causing massive system-side disruptions to rail and bus services. Impacts were especially felt in Brooklyn, where nearly 7 inches of rain had fallen by midday. 

"I want to say to all New Yorkers, this is time for heightened alertness and extreme caution," New York City Mayor Eric Adams warned Friday morning. "If you are home, stay home. If you are at work or school, shelter in place. For now, some of our subways are flooded, and it's extremely difficult to move around the city."
