The low pressure will shift eastward tonight along a stationary boundary extending along far northern Gulf, with a trailing cold front sweeping the southeast Gulf by late Monday night into early Tuesday. Fresh northerly winds will continue behind the front through Tuesday. Winds over the western Gulf will become moderate and easterly Tuesday night through Wednesday while high pressure to the north shifts east. Meanwhile, fresh winds over the eastern Gulf will remain northerly through Thursday. ...CARIBBEAN SEA AND TROPICAL N ATLANTIC FROM 07N TO 19N BETWEEN 55W AND 64W... Relatively weak high pressure north of the region will support moderate to fresh trade winds over most of the Caribbean through mid week, except for pulses of 20 to 25 kt off Colombia. Seas will peak near 8 ft during these strong pulses. Easterly swell in excess of 8 ft will subside over the tropical north Atlantic waters west of 55W tonight, returning by late Tuesday. A cold front will enter the far northwest Caribbean Tuesday night, with fresh to strong northerly winds expected over much of the northwest Caribbean Wednesday through Thursday as strong high pressure builds north of the region. ...SW N ATLANTIC INCLUDING THE BAHAMAS... A stationary front will linger over the northern waters today as low pressure begins to develop along the tail end of the front near the Florida east coast. Strong winds will develop north of the developing low late today with seas building to 8 to 9 ft. Showers and thunderstorms will also persist along and east of the northern Florida coast today. The stationary front will transition to a warm front tonight as the low slowly lifts northeastward and intensifies. Winds north of the low and associated warm front will increase through Monday, reaching near gale to gale by late Monday afternoon north of the warm front, mainly north of 29N between 68W and 73W until Tuesday morning. Seas during this gale will peak around 12 ft. The low will lift north of the region and a cold front will sweep across the Atlantic waters extending from around 31N73W to the central Bahamas Tuesday, then from Bermuda to near the Windward Passage on Wednesday night.
