SYNOPSIS FOR THE THE SW N ATLANTIC INCLUDING THE BAHAMAS
SYNOPSIS
THE PRESSURE GRADIENT BETWEEN A TROUGH THAT EXTENDS
ALONG 59W AND HIGH PRESSURE CENTERED OVER THE CENTRAL ATLANTIC IS
SUPPORTING FRESH TO LOCALLY STRONG NORTHEAST WINDS AND MODERATE
TO ROUGH SEAS NORTHEAST OF THE TROUGH AXIS. THESE CONDITIONS WILL
GRADUALLY SHIFT WESTWARD THROUGH THE EARLY PART OF THE WEEK AS
THE TROUGH DRIFTS WESTWARD. A STATIONARY FRONT ALONG THE
SOUTHEASTERN U.S. COAST WILL GRADUALLY LIFT BACK NORTHWEST AS
WARM FRONT THROUGH THE MIDDLE OF THE WEEK, THEN MAY SLOWLY PUSH
OFFSHORE AGAIN AT THE END OF THE WEEK. EXPECT SCATTERED TO
NUMEROUS SHOWERS AND THUNDERSTORMS OVER THE WESTERN WATERS IN THE
EARLY PART OF THE WEEK.
