000 AGXX40 KNHC 280759 MIMATS Marine Weather Discussion NWS National Hurricane Center Miami FL 359 AM EDT Fri Apr 28 2017 Marine Weather Discussion for the Gulf of Mexico, Caribbean Sea, and Tropical North Atlantic from 07N to 19N between 55W and 64W and the Southwest North Atlantic including the Bahamas ...GULF OF MEXICO... An earlier frontal boundary over the Gulf has dissipated, leaving weak ridging in place along roughly 28N. Moderate to fresh southeast winds are noted north of 26N west of 90W, with gentle to moderate breezes elsewhere and slightly seas. Southerly flow will increase over much of the central and western Gulf through late today, between the stronger ridging over the western Atlantic, and developing low pressure over the Southern Plains. The low pressure will move into the the Central Plains by Saturday, supporting strong southeast winds across the Gulf. Seas will build to 7 to 12 ft with highest seas over the northwest Gulf. A trailing cold front will move off the Texas coast early Sunday, bringing the possibility of winds to minimal gale force to the Mexican coast of Tampico and Veracruz Sunday. The front will move east, with winds and seas diminishing through Monday as the front eventually stalls and dissipates from the Big Bend area of Florida to east central Mexico Tuesday. ...CARIBBEAN SEA AND TROPICAL N ATLANTIC FROM 07N TO 19N BETWEEN 55W AND 64W... A 03 UTC scatterometer pass indicated fresh to strong southeast winds off the north coast of Honduras. Ship observations indicate strong winds are also pulsing off the coast of Colombia. Moderate to fresh trade winds persist elsewhere. These pulses will grow in strength and areal extent through tonight as the gradient tightens between stronger ridging over the western Atlantic and troughing over the Gulf of Mexico. By late Saturday, the building ridge to the north will support strong winds in the Windward Passage and south of Hispaniola near Cabo Beata. Fresh trade winds and building seas will generally prevail across the remainder of the region. Low pressure moving eastward into the Western Atlantic will weaken the ridge to the north and allow winds and seas to subside on through early next week. ...SW N ATLANTIC INCLUDING THE BAHAMAS... Ridging will persist along roughly 28N through Sunday. This will support gentle to moderate breezes north of 24N, with moderate to fresh trade winds farther south, pulsing to fresh to strong at night near the approaches to the Windward Passage through Monday night. Southeast to south return flow will increase east of Florida north of 27N and west of 75W by late Sunday as a cold front approaches the area from the eastern Gulf of Mexico. Looking ahead, the gradient will relax again early next week as the high to the north weakens and the front dissipates. $$ .WARNINGS...Any changes impacting coastal NWS offices will be coordinated through AWIPS II Collaboration Chat, or by telephone: .GULF OF MEXICO... .GMZ017...W CENTRAL GULF FROM 22N TO 26N W OF 94W...
