What are Flash Floods?
Before we dive into NYC-specific scenarios, let's quickly understand what flash floods are. Flash floods are rapid floods of high water flowing over land, usually of short duration and relatively small areal extent. They can occur within minutes or hours of excessive rainfall, snowmelt, or dam/levee failures. Now, you might be wondering, "How do flash floods happen in NYC?" Let's find out!
NYC's Unique Terrain: A Flash Flood Hotspot?
NYC's urban landscape, with its concrete jungles and dense population, might not seem like the perfect breeding ground for flash floods. However, several factors make our city surprisingly susceptible:
- Intense Rainfall: NYC experiences intense, localized rainfall events, often exacerbated by urban heat islands and changes in weather patterns due to climate change. - Impermeable Surfaces: The city's vast concrete and asphalt surfaces don't absorb water well. Instead, they direct rainfall into low-lying areas and underground infrastructure, leading to rapid water buildup. - Underground Infrastructure: NYC's extensive subway and sewer systems can become overwhelmed during heavy rainfall, leading to flooding and even service disruptions.
Historical Flash Flood Events in NYC
NYC has a history of flash flood events, some more severe than others. Here are a couple of examples:
The 2007 Flash Flood
In August 2007, a sudden, intense thunderstorm dropped over 2 inches of rain in just a few hours, causing widespread flooding in Manhattan and Brooklyn. The storm overwhelmed the city's sewer system, leading to subway station closures and stranding commuters.
The 2018 Flash Flood
In July 2018, a quick-moving thunderstorm dumped over 1.5 inches of rain in just 30 minutes, causing flash flooding in Queens and Brooklyn. The storm led to power outages, road closures, and even a few water rescues.
How to Prepare for Flash Floods in NYC
Now that we've explored what flash floods are and how they can happen in NYC, let's talk about how you can prepare and stay safe.
Stay Informed
Sign up for local weather alerts and follow NYC's official emergency management Twitter account (@nycoem). During heavy rainfall, stay tuned to local news and weather updates.
Know Your Risk
Identify low-lying areas in your neighborhood that might be prone to flooding. If you live or work in a flood-prone area, consider investing in flood insurance.
Prepare an Emergency Kit
Assemble an emergency kit with essentials like water, non-perishable food, a flashlight, extra batteries, a first aid kit, and important documents. Keep it in a safe, easily accessible place.
Stay Safe During a Flash Flood
If you're caught in a flash flood:
- Move to Higher Ground Immediately: Flash floods can turn streets into raging rivers in minutes. Get to higher ground as quickly as possible. - Avoid Driving: Never attempt to drive through flooded roads. It only takes a few inches of water to sweep a car away. - Stay Away from Creeks and Streams: Even small bodies of water can turn into raging torrents during a flash flood.
What to Do After a Flash Flood
After the floodwaters recede:
- Check for Injuries: Be cautious when re-entering your home or neighborhood. Watch for structural damage and gas leaks. - Contact Your Insurance Company: If your property has been damaged, file a claim with your insurance company as soon as possible. - Help Your Neighbors: Check on your neighbors, especially the elderly and those with disabilities. Offer help where you can.
