A shallow marine layer in place across the coastal waters will result in dense fog across much of the coastal waters this morning. Then, a moist and unstable air mass associated with the remnants of Tropical Storm Mario will bring showers and potential thunderstorms with rapidly changing winds to the coastal waters as early as late tonight and continuing through Friday. The period of most concern will likely be Wednesday and Thursday. Any thunderstorm that forms will be capable of producing locally gale force winds and rough seas, dangerous lightning, heavy rainfall with reduced visibility, and waterspouts. With dense fog, mariners should be prepared for abrupt visibility changes down to one nautical mile or less. Reduce speeds and be on the lookout for exposed rocks and other vessels, including large ships in the shipping lanes. Use radar or GPS navigation if available, and consider remaining in harbor if such equipment is unavailable. With thunderstorms possible, consider adjusting your mid-week plans now, and continue to monitor the forecast for this evolving weather scenario. $$ Hall
