Living near the coast can be a dream come true for many, with the allure of stunning views and a refreshing sea breeze. However, coastal areas are also vulnerable to natural hazards like coastal flooding, which can pose significant risks to communities and properties. In 2023, it is more critical than ever to understand the difference between a Coastal Flood Advisory and a Coastal Flood Warning, as climate change intensifies the impact of coastal storms. In this blog, we will explore these two alerts, their significance, and how you can stay safe when faced with potential coastal flooding.
Coastal Flood Advisory
A Coastal Flood Advisory is a weather notification issued by the National Weather Service (NWS) to inform the public about the possibility of coastal flooding conditions. It is typically issued when the combination of onshore winds, tides, and other atmospheric factors may cause minor coastal flooding in specific areas. While not as severe as a warning, a Coastal Flood Advisory should still be taken seriously, as it indicates that localized flooding may occur and create hazardous conditions for pedestrians and drivers.
During a Coastal Flood Advisory, it is essential to stay vigilant and monitor updates from local authorities and weather agencies. Residents in the affected areas should take necessary precautions, such as elevating belongings, moving vehicles to higher ground, and avoiding flooded roads or walkways. While it may not warrant immediate evacuation, being prepared and alert can prevent accidents and minimize property damage.
Coastal Flood Warning
On the other hand, a Coastal Flood Warning is a more severe alert issued by the NWS when coastal flooding is imminent or ongoing. It signifies that significant coastal flooding is expected to cause dangerous and potentially life-threatening conditions for communities in the warned area. During a Coastal Flood Warning, immediate action is required to ensure the safety of residents and property.
If a Coastal Flood Warning is in effect, evacuation may be necessary for residents in low-lying coastal regions. Local emergency management authorities will provide guidance on evacuation routes and shelters. It is crucial to heed their advice and evacuate promptly to avoid being caught in dangerous floodwaters. Never attempt to drive or walk through floodwaters, as it only takes a small amount of flowing water to sweep you off your feet or carry away your vehicle.

Staying Safe During Coastal Flooding
Whether you are facing a Coastal Flood Advisory or a Coastal Flood Warning, taking the following safety precautions can help protect yourself and your loved ones:
- Stay Informed: Keep a weather radio or mobile app handy to receive updates from the NWS and local authorities. Follow official social media accounts for real-time information.
- Prepare an Emergency Kit: Have an emergency kit ready with essential supplies like food, water, flashlights, batteries, and first-aid items.
- Secure Outdoor Belongings: Move outdoor furniture, trash cans, and other loose objects indoors to prevent them from becoming hazards in strong winds and floodwaters.
- Elevate Electrical Appliances: Raise electrical appliances and utilities above the expected flood level to avoid damage.
- Evacuate if Necessary: If a Coastal Flood Warning is issued, follow evacuation orders promptly. Do not delay, as floodwaters can rise rapidly.
- Avoid Flooded Areas: Never walk or drive through floodwaters. Even shallow water can hide dangerous debris or have strong currents.
Conclusion
In 2023, as coastal areas face an increasing risk of flooding due to climate change, understanding the difference between a Coastal Flood Advisory and a Coastal Flood Warning is vital for coastal residents and visitors. Both alerts require attention and preparation, but a Coastal Flood Warning demands immediate action to ensure safety. Always stay informed through reliable sources, take necessary precautions during advisories, and follow evacuation orders during warnings. By staying vigilant and prepared, we can protect ourselves and our communities from the impacts of coastal flooding and safeguard the beauty and resilience of coastal living.
