SYNOPSIS FOR THE THE SW N ATLANTIC INCLUDING THE BAHAMAS
SYNOPSIS
SCATTERED SHOWERS AND THUNDERSTORMS EXTENDING FROM
THE BAHAMAS TO BERMUDA ASSOCIATED WITH A MID AND UPPER LEVEL
TROUGH WILL PREVAIL THROUGH MID-WEEK. OTHERWISE, ATLANTIC HIGH
PRESSURE WILL GENERALLY MAINTAIN MODERATE WINDS AND SEAS ACROSS
THE REGION THROUGH THE WEEK. LOOKING AHEAD, A TROPICAL WAVE OVER
THE CENTRAL TROPICAL ATLANTIC IS PRODUCING A LARGE AREA OF
DISORGANIZED SHOWERS AND THUNDERSTORMS. THE DISTURBANCE WILL
BEGIN TO MOVE INTO A MORE FAVORABLE ENVIRONMENT FOR TROPICAL
DEVELOPMENT IN THE NEXT COUPLE OF DAYS, AND A TROPICAL
DEPRESSION
IS LIKELY TO FORM BY THE MIDDLE TO LATTER PART OF THIS WEEK AS
THE SYSTEM MOVES WEST- NORTHWESTWARD AT AROUND 10 KT OVER THE
CENTRAL TROPICAL ATLANTIC. REGARDLESS OF DEVELOPMENT, EXPECT
INCREASING WINDS AND BUILDING SEAS OVER THE SOUTHEASTERN WATERS
BY THU OR FRI.
