The forecasted weather conditions may pose risks to mariners operating in the coastal waters of New Jersey and Delaware. The combination of shifting winds, patchy fog, and potential thunderstorms could reduce visibility and create hazardous conditions, particularly for smaller vessels. Seas are expected to reach up to 4 feet, with localized higher waves near thunderstorms. Mariners should be prepared for sudden changes in weather and sea state, especially during the afternoon and evening when thunderstorms are more likely to develop.
