Choppy seas will continue especially over the offshore Atlantic and

However, marine conditions are forecast to gradually improve 

overnight through the rest of the weekend. Another tropical wave is 

forecast to approach the northeastern Caribbean or move just 

northeast of the area late Sunday night or early Monday morning. This

will enhance shower and thunderstorm activity over portions of the
