At least 15 people were killed in New York City and the surrounding areas when floodwaters from what was left from Hurricane Ida slammed into the city.
An 86-year-old woman was found dead Thursday morning, WABC reported.
The station reported that on Wednesday night, police also found a man, 50, woman, 48, and a 2-year-old boy dead in their home.
A woman in her 20s and a man in his 60s were killed in their flooded apartments in Cypress Hills, Brooklyn.

In Jamaica, Queens, a wall gave way in a home, sending water rushing in, killing two, a 43-year-old woman and a 22-year-old man, around 11 p.m. Wednesday. Officials believe they are mother and son, WPIX reported. The man was pronounced dead at the home. The woman was taken to a hospital where she was declared dead.
In that instance, the street that runs past the home floods frequently and construction had started to repair the issues.
“The purpose of the construction was to make sure this doesn’t happen,” a neighbor who was not identified told WABC. “They took the whole block apart, but obviously city planning didn’t make it work.”
