What This Means For You

Flooding in New York City happens incredibly quickly. Heavy rain can overwhelm storm drains in minutes, especially in low-elevation neighborhoods and older parts of the city. Streets that look passable can turn into moving water, and your basement can fill before you even realize what’s happening.

Across the city, flooding is worsened by clogged storm drains, old sewer systems, and impervious surfaces that prevent water from soaking into the ground. These conditions make flash flooding faster and more dangerous than people expect.

That’s why preparation matters. Knowing what to do before, during, and after a storm can prevent injuries, reduce damage, and save lives.
