000 AGXX40 KNHC 300800 MIMATS Marine Weather Discussion NWS National Hurricane Center Miami FL 400 AM EDT Sun Jun 30 2019 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 weak trough over the north central Gulf will dissipate today as it drifts into the NW Gulf. Weak high pressure will build over the NE Gulf through early next week. Farther south, a trough will develop each afternoon over the Yucatan Peninsula and move offshore to across the Bay of Campeche each evening, bringing fresh to locally strong northeast winds to the eastern Bay of Campeche during the evening hours. Ample deep atmospheric moisture will continue to spread from the northwestward Caribbean toward the southern and SW Gulf through at least Tue, leading to an increase of showers and thunderstorms, some of which may contain strong gusty winds, frequent lightning and rough seas. ...CARIBBEAN SEA AND TROPICAL N ATLANTIC FROM 07N TO 19N BETWEEN 55W AND 64W... A strong pressure gradient between the Bermuda high and low pressure over northern Colombia will support minimal gale force winds again tonight just offshore Colombia, with resultant high seas continuing through Sun night before slowly subsiding beginning on Mon. This gradient will also support strong to near gale force winds over much of the central and SW Caribbean through the period, with moderate to fresh trades elsewhere. Scattered showers and thunderstorms over the NW Caribbean will continue to spread northwestern toward the southern Gulf of Mexico through late tonight. ...SW N ATLANTIC INCLUDING THE BAHAMAS... A relatively weak high pressure ridge will remain along 23N through before shifting northward to 26N Wed night through Thu night. A weak cold front will move across the northern and central waters Mon and Mon night, then stall from near 29N65W to near 26N75 Tue afternoon. Fresh to strong southwest winds will precede the front across the north-central northeast forecast waters. East winds will pulse to strong speeds this afternoon and tonight between the Bahamas and Hispaniola. Gentle to generally moderate winds will continue elsewhere through the period. Ample atmospheric moisture over the western waters including waters around the Bahamas will continue to produce scattered to numerous showers and thunderstorms through this evening. Some of this activity may be accompanied by locally strong gusty winds and rough seas. $$ .WARNINGS...Any changes impacting coastal NWS offices will be coordinated through AWIPS II Collaboration Chat, or by telephone: .GULF OF MEXICO...
