000 AGXX40 KNHC 271816 MIMATS Marine Weather Discussion NWS National Hurricane Center Miami FL 216 PM EDT Thu Apr 27 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... A cold front reaches SW from near Mobile, AL to just S of Brownsville, TX at 25N97W. The front is stalling and beginning to weaken and will lift north again as a weak warm front tonight and Friday morning. Ridging extends W from the western Atlantic into the eastern Gulf ahead of the front along 28N. After the front dissipates and lifts N, SE to S winds will increase to fresh to strong across the central and western Gulf Friday and Saturday, between the Atlantic ridge to the east and deepening low pressure moving from W Texas to the Central Plains. Seas will build to 12 ft in response over the NW Gulf late Saturday and early on Sunday. A cold front trailing the low will head SE into the NW Gulf early Sunday. Model solutions and ensemble guidance have come into a little better agreement on a minimal gale event Sunday night in the favored areas along the coast near Veracruz and Tampico. Have accordingly brought 35 kt winds into the forecast during this time frame. At any rate, the duration of the strong winds will be brief, as the front stalls and dissipates from central Florida to the eastern Bay of Campeche by late Monday. ...CARIBBEAN SEA AND TROPICAL N ATLANTIC FROM 07N TO 19N BETWEEN 55W AND 64W... Moderate to fresh trade winds are generally noted over the Caribbean and the tropical north Atlantic waters. Ridging to the north of this region is rebuilding. Localized fresh to strong winds will pulse near the Gulf of Honduras and along the coast of northern Colombia during the overnight hours tonight. These pulses will grow in strength and areal extent by Friday night 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 N and allow winds and seas to subside on Sunday and Monday. ...SW N ATLANTIC INCLUDING THE BAHAMAS... Ridging currently extending WSW from 31N62W to the Florida coast near Cape Canaveral will remain in place and maintain moderate SE to S breezes and 4 to 6 ft seas in the open Atlantic east of the Bahamas through Friday night. Moderate to fresh trade winds will prevail south of 22N Saturday through Sunday as high pressure to the N strengthens. Fresh to strong trades will affect the approaches to the Windward Passage Friday through Monday night. SE to S return flow will increase east of Florida N of 27N and W 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 N 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...
