A month's worth of rain, more than 4 inches, inundated parts of Brooklyn in just three hours, posing a significant danger to residents.

New York City Mayor Eric Adams addressed the ongoing crisis, emphasizing that the dangerous weather conditions are far from over and Guv Kathy Hochul declared a state of emergency for New York City, Long Island, and the Hudson Valley, urging residents to stay home due to hazardous travel conditions.

Firefighters conducted daring rescue operations in flooded basements, providing assistance to those affected by torrents of water.

The floodwater infiltrated subways and railways, leading to major disruptions, including suspensions of service on 10 train lines in Brooklyn. 

The National Weather Service issued a Level 3 of 4 "moderate" risk for flash flooding, warning of a "dangerous and life-threatening situation" for millions of residents; it was extended to a wide swath of the Northeast, affecting millions of people, with heavy rain expected to continue in various regions.

Flooding also forced the closure of the historic Marine Air Terminal in New York's LaGuardia airport, causing flight delays across all three NYC area airports.
