As heavy rain hit parts of New York City, people had to deal with strong downpours and rising water levels.
In Connecticut and Long Island, more rain was expected. While no one lost their lives, there were chaotic scenes as people waded through knee-deep water and left their cars on flooded roads.
New York City firefighters rescued at least 15 people from cars stuck in the flooding, and they helped six people from flooded basement apartments.
The heavy rain also disrupted transportation, flooding subway stations and train tracks.
JFK airport saw more than 8 inches of rain, making it the wettest day since 1948, and La Guardia airport had almost 5 inches of rain, causing flight cancellations.
The Central Park Zoo was so flooded that a sea lion briefly escaped from its enclosure.
This storm has made it clear that New York City needs to be better prepared for extreme weather caused by climate change.
