SYNOPSIS  
HURRICANE ERIN IS WELL NORTHWEST OF THE REGION,   
HOWEVER, LONG-PERIOD N SWELL WILL BEGIN TO IMPACT THE ATLANTIC   
WATERS THIS WEEKEND. IN THE WAKE OF ERIN, CENTRAL ATLANTIC   
PRESSURE WILL BUILD WEST-SOUTHWESTWARD TOWARD THE BAHAMAS. THIS   
WILL ALLOW FOR THE NORMAL TRADE WIND FLOW TO RETURN TO THE   
REGIONAL WATERS THROUGH THE PERIOD. MEANWHILE, A TROPICAL WAVE   
LOCATED OVER THE CENTRAL TROPICAL ATLANTIC CONTINUES TO PRODUCE A  
BROAD AREA OF DISORGANIZED SHOWERS AND THUNDERSTORMS.   
ENVIRONMENTAL CONDITIONS APPEAR CONDUCIVE FOR GRADUAL DEVELOPMENT  
OF THIS SYSTEM, AND A TROPICAL DEPRESSION COULD FORM LATE THIS   
WEEK OR OVER THE WEEKEND WHILE IT MOVES NEAR OR TO THE NORTH OF   
THE NORTHERN LEEWARD ISLANDS. THERE IS A LOW CHANCE OF   
DEVELOPMENT WITHIN THE NEXT 48 HOURS, AND A MEDIUM CHANCE WITHIN   
THE NEXT 7 DAYS.
