Coastal Flood Advisory: What You Need to Know
Coastal flooding remains one of the most pressing natural hazards affecting coastal communities across the United States. Today, several coastal regions are under a Coastal Flood Advisory, warning residents and visitors to be alert and prepared for rising water levels and the risks they bring. This article breaks down what the advisory means, where it’s currently in effect, and how you can stay safe during such events.
Understanding Coastal Flood Advisory: Definition and Causes
A Coastal Flood Advisory is issued by the National Weather Service (NWS) when minor flooding along the coast is expected. Unlike more severe warnings such as a Coastal Flood Warning or a Hurricane Warning, an advisory indicates flooding that may cause inconvenience but typically does not pose a serious threat to life or property if precautions are followed.
What Causes Coastal Flooding?
Coastal flooding can result from several natural factors, often working in combination:
-
High tides (especially during spring or king tides)
-
Storm surges from hurricanes or tropical storms
-
Strong onshore winds pushing seawater inland
-
Heavy rainfall contributing to rising water levels
-
Sea level rise due to climate change, making flooding more frequent and severe
Today’s advisory is primarily due to an unusual combination of strong tidal forces and persistent winds pushing seawater into vulnerable coastal areas.
Coastal Flood Advisory Areas Today: Detailed Overview
According to the latest updates from the National Weather Service, the following states and counties are currently under a Coastal Flood Advisory:
| State | Counties/Cities Affected | Advisory Duration | Expected Flooding Type |
|---|---|---|---|
| Florida | Miami-Dade, Broward, Palm Beach | 6 AM - 8 PM | Minor coastal flooding |
| New Jersey | Ocean, Monmouth, Atlantic | 7 AM - 9 PM | Tidal flooding in low-lying areas |
| Massachusetts | Barnstable, Dukes, Nantucket | 8 AM - 10 PM | Flooding near waterfront |

This advisory is particularly critical for low-lying communities, coastal roads, and recreational waterfront areas where water levels are expected to rise above normal high tide lines.
How to Prepare for a Coastal Flood Advisory: Essential Tips
Being proactive is key when a Coastal Flood Advisory is issued. Here are practical steps to keep you and your family safe:
1. Monitor Local Updates
Stay tuned to your local National Weather Service office, local news channels, or official social media accounts for continuous updates and changes in the advisory.
2. Avoid Flooded Roads
Never attempt to drive through flooded streets. Water depth can be deceptive, and vehicles can easily be swept away.
3. Protect Your Property
If possible, elevate valuables and electrical equipment off the floor. Consider sandbagging vulnerable entrances if flooding is expected near your home.
4. Prepare an Emergency Kit
Include essentials such as bottled water, non-perishable food, medications, flashlights, batteries, and a portable phone charger.
5. Plan Your Evacuation Route
Know the safest way to higher ground or designated shelters if the situation worsens.
