SYNOPSIS FOR THE THE SW N ATLANTIC INCLUDING THE BAHAMAS
SYNOPSIS
THE PRESSURE GRADIENT BETWEEN A 1015 MB LOW CENTERED
NEAR 26N64W WITH ASSOCIATED TROUGH AND HIGH PRESSURE CENTERED
OVER THE CENTRAL ATLANTIC IS SUPPORTING FRESH TO LOCALLY STRONG
NORTHEAST WINDS AND MODERATE TO ROUGH SEAS NORTH AND NORTHEAST OF
THE LOW. THESE CONDITIONS WILL GRADUALLY SHIFT WESTWARD THROUGH
MID- WEEK AS THE LOW AND TROUGH DRIFT WESTWARD. WINDS AND SEAS
WILL START TO DECREASE MID- WEEK AS THE LOW AND TROUGH START TO
WEAKEN. A STATIONARY FRONT ALONG AND JUST OFFSHORE THE
SOUTHEASTERN U.S. COAST WILL GRADUALLY LIFT BACK NORTHWEST AS
WARM FRONT THROUGH MID-WEEK, THEN MAY SLOWLY PUSH OFFSHORE AGAIN
AT THE END OF THE WEEK.
