000 AGXX40 KNHC 160805 MIMATS Marine Weather Discussion NWS National Hurricane Center Miami FL 405 AM EDT Sat Mar 16 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... As of 06Z, the cold front is along a position from near Cross City, Florida to 26N90W and to 23N94W where it becomes stationary to 21N94W and to inland Mexico at 18N94W. Strong high pressure is building eastward in its wake. A recent Ascat pass along with current buoy observations reveal a large swath of strong to near gale force winds covering the waters west and northwest of the front. Seas are in the 8 to 12 ft behind the front, except for much higher seas of 10 to 16 ft in the far SW Gulf behind the front where minimal northwest gale force winds are occurring. By early this afternoon, the front will reach from near Tampa Bay, Florida to near 25N90W and to 23N94W, continuing from there as a stationary front to just inland Mexico at 18.5N93W. The gradient behind it will weaken just enough to allow for the ongoing gale force winds in the far SW Gulf to diminish to near strong northwest to north winds. Winds elsewhere northwest of the front will be in the strong range with seas of 8 to 11 ft. The seas in the far SW Gulf will only subside slightly during this afternoon and evening. The cold front will reach from reach from SW Florida by late tonight and to 23N89W and to 22N93W, where it will continue as stationary to 18.5N93W. Winds in the far SW Gulf west of the front will be northwest at 20 to 25 kt, with seas of 8 to 11 ft. The strong northeast winds elsewhere northwest of the front will diminish in coverage to cover the area from 24N to 26N between 92W and 97W, with seas of 8 to 10 ft. The cold front will push southward some more reaching the Straits of Florida late Sun into Mon, while the stationary part weakens. The cold front will again become stationary on Tue along the northwest coast of Cuba and lower Straits of Florida, southwestward to along or just offshore the northern and northwest coast of the Yucatan Peninsula through early on Wed. The stationary front is expected to gain another southward push as a cold front on Wed across northwest Cuba, but as a rather weak frontal boundary. A trough will linger in the SW Gulf from Sun through Wed. A tight pressure gradient between it and high pressure over the northern and central Gulf will allow for strong northwest winds to exist generally to the south of 21N and west of 95W Sun through early on Wed. The high pressure currently building behind the cold front as stated earlier will shift eastward through Wed, but only weaken slightly. ...CARIBBEAN SEA AND TROPICAL N ATLANTIC FROM 07N TO 19N BETWEEN 55W AND 64W... High pressure north of the area will support fresh to strong trade winds over much of the central Caribbean Sea through Wed. These winds will decrease in coverage Tue through Wed night. Northeast winds will pulse to minimal gale force at night tonight and Sun night, with some possibility that they may return on Mon night. Otherwise, moderate to fresh trade winds will continue across the remainder of the area through the middle part of next week. ...SW N ATLANTIC INCLUDING THE BAHAMAS... High pressure across the western Atlantic will shift southeastward and weaken through Sun night. A cold front has recently moved to just offshore the Georgia and northeast Florida coasts. This front will reach from near 31N77W to Stuart, Florida by early Saturday afternoon, from near Bermuda to near 29N74W and stationary to southern Florida by early on Sun. The front will eventually become stationary from near 29N65W across the central Bahamas to northwest Cuba by late Sun. Low pressure may develop along the front Tue through Wed and track northeastward, with increasing winds and seas expected across much of the central and western waters, with increasing winds and building seas expected in much of the central and western waters. Stay tuned to future forecasts that will provide more details on this upcoming weather event. $$ .WARNINGS...Any changes impacting coastal NWS offices will be coordinated through AWIPS II Collaboration Chat, or by telephone: .GULF OF MEXICO... .GMZ023...SW GULF S OF 22N W OF 94W...
