SYNOPSIS  
HURRICANE ERIN IS WELL NORTHWEST OF THE REGION,   
HOWEVER, LONG-PERIOD N SWELL WILL BEGIN TO IMPACT THE ATLANTIC   
WATERS ON FRI. IN THE WAKE OF ERIN, CENTRAL ATLANTIC HIGH   
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 SEVERAL HUNDRED MILES EAST OF THE LEEWARD ISLANDS IS   
PRODUCING A BROAD AREA OF DISORGANIZED SHOWERS AND THUNDERSTORMS.  
ENVIRONMENTAL CONDITIONS APPEAR CONDUCIVE FOR GRADUAL DEVELOPMENT  
OF THIS SYSTEM, AND A TROPICAL DEPRESSION IS LIKELY TO FORM BY   
THIS WEEKEND WHILE IT MOVES NEAR OR TO THE NORTH OF THE NORTHERN   
LEEWARD ISLANDS.
