What is Flash Flooding?

Flash flooding is defined as a rapid flooding of low-lying areas, typically within six hours of heavy rainfall. Unlike regular flooding, which may develop over days, flash floods can occur within minutes, catching people off-guard.

Key characteristics of flash flooding include:

• Rapid onset and short duration
• High intensity of rainfall
• Localized impact, often affecting small areas

Causes of Flash Flooding in NYC

Several factors contribute to the occurrence of flash flooding in New York City:

1. Heavy Rainfall

Intense storms can bring a significant amount of rain in a short period, overwhelming the city's drainage systems.

2. Urbanization

The extensive development and paving of land reduce natural absorption, leading to increased runoff.

3. Climate Change

Rising temperatures and changing precipitation patterns are intensifying storm events, resulting in more frequent flash floods.

Historical Flash Flood Events in NYC

New York City has a history of notable flash flooding events. Some of the most significant incidents include:

• Hurricane Harvey (2017): While primarily affecting Texas, the remnants of this storm brought heavy rainfall to NYC, causing flash floods.
• Hurricane Ida (2021): This event was particularly devastating, resulting in record rainfall and widespread flash flooding across the city.
• July 2021 Storm: An intense storm led to significant flooding in parts of Queens and Brooklyn, highlighting the city's vulnerability.
