Coastal Flood Advisory: Stay Informed and Prepared

What is a Coastal Flood Advisory?

A coastal flood advisory is issued by the National Weather Service (NWS) when flooding is possible within the next 24 to 48 hours. This warning is typically issued several hours before flooding is expected to occur. The NWS issues this advisory to provide ample time for residents and businesses to take precautions and prepare for potential flooding.

Coastal Flood Risks

Coastal flooding is a major concern for communities along the coastline. Several factors can contribute to coastal flooding, including storm surges, heavy rainfall, snowmelt, and high tides. These factors can cause water levels to rise rapidly, leading to flooding that can damage property, infrastructure, and businesses.

According to the Federal Emergency Management Agency (FEMA), coastal flooding is among the costliest and deadliest natural disasters in the United States. In 2017, Hurricane Harvey caused an estimated \$125 billion in flood damage.

Impacts of Coastal Flooding

Coastal flooding can have several impacts on communities, including:

• Property damage: Flooding can damage homes, businesses, and other structures. Water can cause structural problems, damage electrical systems, and destroy personal belongings.
• Infrastructure damage: Flooding can damage roads, bridges, and other infrastructure. This damage can disrupt transportation and access to essential services.
• Business disruptions: Flooding can force businesses to close temporarily, which can lead to lost revenue and productivity.
• Health hazards: Flooding can pose a health hazard by creating a breeding ground for mosquitoes and other disease-carrying pests. Floodwater can also contain contaminants and pose a risk to human health.

Preparing for Coastal Flooding

There are several things you can do to prepare for coastal flooding, including:

1. Stay informed: Monitor weather forecasts and pay attention to coastal flood advisories from the NWS.
2. Develop an evacuation plan: In the event of a coastal flood advisory, you may need to evacuate your home. Have a plan in place for where you will go and how you will get there.
3. Protect your property: Elevate valuables and important documents to higher floors. Place sandbags around doors and windows to prevent flooding.
4. Gather supplies: Stock up on food, water, and other emergency supplies in case you need to evacuate.
5. Have an emergency kit: Keep an emergency kit in your car and home with essential items such as a first-aid kit, flashlight, and radio.

Responding to Coastal Flooding

If you are in an area that is experiencing coastal flooding, there are several things you should do, including:

1. Stay away from floodwaters: Floodwaters can be dangerous and contain contaminants. Avoid walking or driving through floodwaters.
2. Do not use electrical equipment near water: This can pose a serious electrical hazard.
3. If you must evacuate, do so immediately: Do not wait until it is too late. Floodwaters can rise rapidly, making it difficult to evacuate later on.

Conclusion

Coastal flooding is a serious threat to communities along the coastline. By understanding the risks and taking steps to prepare, you can reduce your vulnerability and protect your loved ones and property.
