Introduction

Coastal flood warnings are critical alerts issued by meteorological agencies like the National Weather Service to inform the public about the potential for or the presence of coastal flooding. Coastal flooding can be destructive, causing significant damage to homes, businesses, and infrastructure, as well as posing a direct threat to human life. The increasing frequency and severity of these events, often linked to climate change and rising sea levels, underscore the importance of understanding and heeding these warnings.

What & Why

Coastal flood warnings are issued for a variety of reasons, most of which are weather-related. Here’s a breakdown: — Millville, NJ: Your Guide To 08332 - Real Estate & More

• Storm Surge: Perhaps the most dangerous cause, storm surge is the abnormal rise of water generated by a storm. The intensity of a storm surge is dependent on storm characteristics such as the storm's intensity, size, speed, and angle of approach. Hurricanes and nor'easters are common causes of storm surge.
• High Tides: Regular high tides can exacerbate coastal flooding, especially when combined with other factors.
• Wave Action: Strong winds and storms can generate large waves that overtop coastal defenses, leading to flooding.
• Heavy Rainfall: Intense rainfall, especially when combined with saturated ground or poor drainage, can contribute to flooding.
• Sea Level Rise: Climate change is causing sea levels to rise, which increases the likelihood and severity of coastal flooding.

The Benefits of Coastal Flood Warnings

Coastal flood warnings offer a range of benefits:

• Early Warning: Provide advance notice, enabling individuals and communities to prepare for potential flooding.
• Risk Reduction: Help reduce the risk of injury, loss of life, and property damage.
• Preparedness: Encourage people to take preventative measures, such as moving belongings to higher ground, securing property, and planning evacuation routes.
• Community Awareness: Raise awareness about flood risks and promote community resilience.
