SYNOPSIS FOR THE THE SW N ATLANTIC INCLUDING THE BAHAMAS
SYNOPSIS
A SURFACE TROUGH EXTENDS FROM NEAR 31N55W TO NEAR
19N60W. THE PRESSURE GRADIENT BETWEEN THIS TROUGH AND HIGH

TO E WINDS AND ROUGH SEAS THROUGH THE WEEKEND FROM THE BAHAMAS TO
THE GREATER ANTILLES. WINDS AND SEAS WILL SLOWLY DIMINISH WEST
OF 70W EARLY NEXT WEEK. CLOSER TO THE TROUGH, WHERE WEAK LOW

PREVAIL.
