Special Marine Warning Issued for Coastal Waters Along North Carolina and South Carolina
A Special Marine Warning has been issued for portions of the western North Atlantic coastal waters, including areas from Cape Fear, North Carolina to Little River Inlet, South Carolina, and from Little River Inlet to Murrells Inlet, South Carolina out 20 nautical miles.
Strong thunderstorms moving across the coastal waters are capable of producing dangerous marine conditions, including wind gusts up to 40 knots and small hail up to three-quarters of an inch.
Mariners operating in or near these waters should prepare for rapidly changing conditions as storms move through the area.
Areas Impacted by the Marine Warning
The warning includes:
- Coastal waters from Cape Fear, NC to Little River Inlet, SC out 20 NM
- Coastal waters from Little River Inlet to Murrells Inlet, SC out 20 NM
Boaters, fishermen, and coastal operators should monitor updated weather information and be prepared to seek safe harbor if thunderstorms approach.
Storm Hazards Expected
🌊 Strong Wind Gusts
Thunderstorms may produce 40-knot wind gusts, creating hazardous conditions for smaller vessels. Strong winds can lead to:
- Sudden increases in wave heights
- Difficult navigation
- Reduced visibility
- Dangerous conditions near inlets and coastal passages
🧊 Small Hail Possible
Storm cells may also produce hail less than 0.75 inches in diameter. While small hail is not typically a major marine threat, it can reduce visibility and create additional hazards during thunderstorms.
⛈️ Strong Thunderstorms
Thunderstorms over coastal waters can intensify quickly, bringing:
- Frequent lightning
- Heavy rainfall
- Sudden wind shifts
- Rough seas
Marine Safety Tips During Thunderstorms
Boaters in the warning area should:
- Monitor NOAA Weather Radio and marine forecasts
- Move to safe harbor when thunderstorms approach
- Wear life jackets while underway
- Avoid open water during severe storms
- Secure loose equipment on deck
- Stay away from exposed areas during lightning
Never attempt to outrun a rapidly approaching thunderstorm if safe shelter is nearby.
