What & Why

Coastal flood warnings are put into effect to warn the public of the dangers of imminent or ongoing coastal flooding. This flooding can be caused by several factors, primarily severe weather events such as hurricanes, nor'easters, and tsunamis. The most common cause is storm surge, an abnormal rise of water generated by a storm's winds pushing water toward the shore. Other factors include high tides and heavy rainfall, which can exacerbate flooding.

Flooding is considered one of the most costly natural disasters, threatening lives and properties. Coastal areas are particularly vulnerable because of their proximity to the water, making them prone to damage. Warnings are vital because they enable people to prepare, such as by evacuating vulnerable areas, moving valuables to higher ground, and securing their homes and businesses. They also allow emergency services to be better prepared to respond to the disaster.

Benefits of Coastal Flood Warnings

• Protection of life: Early warnings provide time for evacuations and other safety measures, reducing the risk of fatalities.
• Property damage mitigation: Residents can protect their property by moving valuables, sandbagging, and securing their homes.
• Emergency preparedness: Emergency services can mobilize resources and prepare for rescue operations.
• Public awareness: Raise awareness about the dangers of coastal flooding and the importance of preparedness.

Risks of Coastal Flood Warnings

• False alarms: Though rare, false alarms can lead to complacency and a reduced sense of urgency during actual events.
• Overreaction: Sometimes, warnings can cause people to make decisions that could endanger them, such as attempting to drive through flooded areas.
• Economic impact: Coastal businesses may suffer disruptions and financial losses if they are required to close for evacuations.

Examples & Use Cases

Coastal flood warnings have significant impacts across the United States, and here are some examples:

• Hurricane Katrina (2005): Caused catastrophic flooding along the Gulf Coast, with storm surge exceeding 20 feet in some areas. This highlighted the devastating impact of coastal flooding and the importance of effective warning systems and preparedness.
• Hurricane Sandy (2012): Brought massive flooding to the New Jersey and New York coasts. The storm surge flooded subways, and tunnels, and damaged infrastructure, underscoring the need for robust flood defenses.
• Hurricane Harvey (2017): Extensive flooding in Houston, Texas, was caused by unprecedented rainfall, which compounded the effects of coastal flooding. This emphasized the need for comprehensive flood management strategies.
• Nor'easters on the East Coast: These storms can bring significant coastal flooding, especially during high tides. These events stress the importance of regular updates and local awareness.

Best Practices & Common Mistakes

To maximize your safety and preparedness during a coastal flood warning, consider these best practices and common mistakes to avoid:

Best Practices

• Develop a Family Emergency Plan: This should include evacuation routes, meeting points, and communication strategies.
• Assemble an Emergency Kit: Include essential supplies like food, water, first aid, medications, and a flashlight.
• Stay Informed: Monitor weather updates from reliable sources and heed the instructions of local authorities.
• Understand Flood Zones: Know your area’s flood risk and the elevation of your property.
• Maintain Flood Insurance: Protect your property with flood insurance, as standard homeowners' policies typically don’t cover flood damage.

Common Mistakes to Avoid

• Ignoring Warnings: Failing to take warnings seriously is a major risk factor.
• Driving Through Flooded Roads: Water can be deeper than it appears, and even a few inches can sweep a car away.
• Underestimating the Risk: Coastal flooding can occur even in non-hurricane weather conditions.
• Lack of Preparation: Not having an emergency plan, kit, or insurance can put you at risk.
• Delaying Evacuation: Hesitating to evacuate when ordered or advised increases your risk of getting trapped.
