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 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 WILL
ENCOUNTER ENVIRONMENTAL CONDITIONS CONDUCIVE FOR GRADUAL TROPICAL
DEVELOPMENT, AND A TROPICAL DEPRESSION COULD FORM BY THIS
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.
