Coastal Flood Advisory: Prepare for Rising Waters

Issued by the National Weather Service

What is a Coastal Flood Advisory?

A Coastal Flood Advisory is issued when flooding is expected to occur within the next 24 hours along coastal areas due to high tide, storm surge, or other factors. Flooding may occur in low-lying areas, such as beaches, boardwalks, and coastal roads.

When to Prepare

• Monitor weather reports: Pay attention to forecasts for high tides, storm surges, and other coastal hazards.
• Check local emergency alerts: Listen to local news and radio stations for updates on any potential flooding events.
• Be ready to evacuate: If flooding is imminent, be prepared to move to higher ground.

Impacts of Coastal Flooding

• Structural damage: Flooding can damage homes, businesses, and other structures, causing significant financial loss.
• Infrastructure disruptions: Roads and bridges can be closed due to flooding, hindering transportation and emergency response efforts.
• Health risks: Standing water can harbor bacteria and other contaminants, posing a health risk to residents.
• Economic losses: Flooding can disrupt businesses, tourism, and other economic activities, leading to lost revenue and job losses.

What to Do During a Coastal Flood Advisory

Before the Flood:

• Secure loose objects: Bring in outdoor furniture, grills, and other items that could be swept away by flooding.
• Elevate valuables: Move important belongings to higher floors or shelves.
• Stock up on supplies: Gather essential items such as food, water, first aid kits, and batteries.
• Prepare an evacuation plan: Identify safe routes and meeting places in case of evacuation.
• Stay informed: Monitor weather reports and emergency alerts for updates on the flood advisory.

During the Flood:

• Avoid driving: Do not attempt to drive through flooded areas. Even a few inches of water can disable your vehicle.
• Stay away from downed power lines: Report any downed power lines to the appropriate authorities.
• If evacuation is ordered, leave immediately: Follow the instructions of local officials and evacuate to higher ground.
• Stay calm and follow emergency instructions: Listen to local authorities for guidance and do not hesitate to seek help if needed.

Why Coastal Flood Advisories Matter

Coastal flooding is a serious threat to coastal communities. According to the National Oceanic and Atmospheric Administration (NOAA), the United States has experienced an average of 10 coastal flood events per year since 2000, causing billions of dollars in damage.

These events are expected to become more frequent and severe due to climate change, as sea levels rise and storm intensity increases. By preparing for and responding appropriately to coastal flood advisories, communities can minimize the impacts of flooding and protect their residents and infrastructure.

Benefits of Preparing for Coastal Flooding

• Reduced property damage: Proper preparation can help reduce the risk of damage to homes, businesses, and other structures.
• Improved public safety: By evacuating early and staying informed, residents can minimize their risk of injury or death during a flood event.
• Reduced economic losses: By protecting businesses and infrastructure, communities can avoid the economic setbacks that often follow flooding.
• Enhanced community resilience: By working together to prepare for and respond to coastal flooding, communities can build resilience and better withstand the impacts of these events.

Tips and Tricks for Staying Safe During a Coastal Flood Advisory

• Know your flood risk: Determine if your home or business is located in a flood-prone area and identify potential evacuation routes.
• Install flood barriers: Consider installing flood barriers such as sandbags or flood gates to protect your property from rising waters.
• Use flood insurance: Flood insurance can help cover the costs of flood damage to your property and belongings.
• Create a flood preparedness kit: Pack a kit containing essential items such as water, food, first aid supplies, and a weather radio.
• Educate your family and neighbors: Share information about coastal flooding preparedness and evacuation procedures with your family and neighbors.
• Practice your evacuation plan: Conduct drills to ensure everyone in your household knows where to go and how to evacuate safely.
• Stay connected: During a flood event, stay informed about the latest weather conditions and evacuation orders through local news, radio, or social media.
