000 AGXX40 KNHC 061714 MIMATS Marine Weather Discussion NWS National Hurricane Center Miami FL 114 PM EDT Thu Jul 6 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 ridge of high pressure prevails over the northern waters. Latest satellite derived winds and seas along with ship, buoy, and CMAN data depict light to gentle winds prevailing the Gulf waters. Seas are in the 1-2 ft range over the northeastern Gulf, 3-4 ft over the southwestern Gulf, and 2-3 ft over the remainder of the Gulf waters. The ridge will prevail over the northern waters through early next week. A thermal trough will develop during the evening hours over the Yucatan Peninsula before pushing offshore into the SW Gulf each night. A surge of moderate to fresh N-NE winds will accompany this trough, with seas briefly building to 5 ft in association with these winds. Otherwise, gentle to moderate E to SE winds and seas of 4 ft or less will prevail across much of the Gulf through Sun. ...CARIBBEAN SEA AND TROPICAL N ATLANTIC FROM 07N TO 19N BETWEEN 55W AND 64W... A ridge of high pressure prevails north of area. Latest satellite derived winds and seas along with ship, buoy, and CMAN data depict fresh to strong winds over the central Caribbean, moderate to locally fresh winds over the eastern and western Caribbean, and gentle to moderate winds over the tropical north Atlantic forecast zones. Seas are in the 8-11 ft range over the central Caribbean, 4-6 ft over the eastern Caribbean, 3-5 ft over the western Caribbean, and 5-7 ft over the tropical north Atlantic forecast zones. These general conditions will prevail over the Caribbean waters through the end of the week. Tropical Depression Four, or its remnants, will move northeast of the Lesser Antilles this weekend, and north of Puerto Rico early next week. This will help to loosen the pressure gradient over the Caribbean waters bringing a decrease in winds and seas this weekend. ..SW N ATLANTIC INCLUDING THE BAHAMAS... A ridge of high pressure prevails over the northern waters. Latest satellite derived winds and seas along with ship, buoy, and CMAN data depict light to gentle winds over the northern waters with gentle to moderate winds prevailing over the southern waters. Seas are in the 2-3 ft range over the northern waters, 4-5 ft over the southern waters outside the Bahamas, and 1-3 ft west of the Bahamas. The ridge will prevail over the northern waters through the forecast period. Tropical Depression Four, or its remnants, will move northeast of the Lesser Antilles this weekend, and north of Puerto Rico early next week. This will act to slightly weaken the ridge. $$ .WARNINGS...Any changes impacting coastal NWS offices will be coordinated through AWIPS II Collaboration Chat, or by telephone: .GULF OF MEXICO...
