The advisory will primarily affect small craft operators in the Florida Keys, including Hawk Channel, the Straits of Florida, and the Gulf of America. Fresh to strong northeasterly winds and rough seas, with wave heights reaching up to 9 feet, pose significant risks to navigation. Squally conditions and thunderstorms may further reduce visibility and increase the likelihood of hazardous situations. Mariners are advised to exercise caution and prepare for challenging conditions, especially during nighttime hours when winds are expected to peak.
