SYNOPSIS FOR THE THE SW N ATLANTIC INCLUDING THE BAHAMAS
SYNOPSIS
ATLANTIC HIGH PRESSURE WILL MAINTAIN MODERATE WINDS
AND SEAS ACROSS THE REGION THROUGH THE WEEK. A BROAD AREA OF LOW
PRESSURE IS LOCATED ABOUT MIDWAY BETWEEN THE WINDWARD ISLANDS
AND THE COAST OF WEST AFRICA. THIS SYSTEM IS SHOWING SIGNS OF
ORGANIZATION, AND IS EXPECTED TO MOVE THROUGH A FAVORABLE
ENVIRONMENT FOR FURTHER DEVELOPMENT. A TROPICAL DEPRESSION OR
TROPICAL STORM IS LIKELY TO FORM BY THE MIDDLE TO LATTER PART OF
THIS WEEK WHILE THE SYSTEM MOVES WEST-NORTHWESTWARD AT 10 TO 15
KT OVER THE CENTRAL TROPICAL ATLANTIC. THERE IS A MEDIUM CHANCE
OF TROPICAL FORMATION OVER THE NEXT 48 HOURS AND A HIGH CHANCE
OVER THE NEXT 7 DAYS. REGARDLESS OF DEVELOPMENT, EXPECT
INCREASING WINDS AND BUILDING SEAS OVER THE SOUTHEASTERN WATERS
BY THU INTO FRI.
