The National Weather Service has issued a Special Marine Warning for the Atlantic coastal waters from the Volusia-Brevard County Line to Sebastian Inlet, including both the 0-20 nautical mile and 20-60 nautical mile marine zones. Strong thunderstorms moving across the coastal waters are capable of producing wind gusts up to 49 knots (56 mph) and hail smaller than 0.75 inches, creating hazardous conditions for anyone on the water.
Areas Under the Special Marine Warning
- Volusia-Brevard County Line to Sebastian Inlet (0-20 NM)
- Volusia-Brevard County Line to Sebastian Inlet (20-60 NM)
Boaters, anglers, paddlecraft users, and anyone navigating offshore waters should monitor weather conditions closely as thunderstorms can intensify rapidly over the Atlantic.
Marine Hazards
The strongest thunderstorms may produce:
- Wind gusts up to 49 knots (56 mph)
- Hail smaller than 0.75 inches
- Frequent cloud-to-water lightning

- Sudden wind shifts capable of overturning small vessels
Special Marine Warnings are issued when thunderstorms produce winds of 34 knots or greater, posing an immediate threat to marine interests.
Safety Tips for Boaters
If you are on the water:
- Head to the nearest safe harbor immediately.

- Avoid open water until storms have passed.
- Secure loose equipment and prepare for rapidly changing wave conditions.
- Stay tuned to NOAA Weather Radio or trusted weather sources for updated warnings.
Florida’s Summer Storm Pattern
During Florida’s summer, sea breeze boundaries frequently trigger strong afternoon thunderstorms that quickly move over the Atlantic coastal waters. Even when general marine conditions appear calm, localized thunderstorms can produce dangerous winds, lightning, and rough seas with little warning.
