What is a Coastal Flood Advisory?
A Coastal Flood Advisory is issued by the National Weather Service (NWS) when flooding is expected to occur within the next 24 hours along the coast. This advisory is typically issued when water levels are expected to reach 1 to 2 feet above normal high tide, but below the level of serious flooding.
Reasons for Issuing a Coastal Flood Advisory
- High tide coinciding with strong onshore winds
- Heavy rainfall or snowmelt
- Storm surge from a tropical cyclone or extratropical storm
- Dam or levee failure

- Erosion of beaches and dunes
- Damage to roads, bridges, and buildings
- Flooding of low-lying areas, such as homes, businesses, and parks
- Contamination of drinking water sources
- Disruption of transportation and utilities
What to Do When a Coastal Flood Advisory is Issued
- Monitor weather updates and follow instructions from local officials.
- Be prepared to evacuate if necessary.
- Move valuables to higher ground.
- Avoid driving through flooded areas.
- Stay informed about road closures and detours.
