000 AGXX40 KNHC 041950 MIMATS Marine Weather Discussion NWS National Hurricane Center Miami FL 250 PM EST Wed Dec 4 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... Weak high pressure over the western and central Gulf will begin to shift east of the area late Thu in response to a cold front that will enter the NW Gulf on Fri. Weak low pressure is expected to form along the frontal boundary late Fri through Sat night over the north-central Gulf, then lift north of the area on Sun. Fresh to strong east to southeast winds are expected to the northeast of the low. Atlantic high pressure will then build westward across the Gulf through Mon, and help set up fresh to strong southerly flow over much of the western Gulf ahead of an approaching strong cold front. This front is expected to move into the NW Gulf Mon night into Tue followed by strong to possible near gale force northerly winds. ...CARIBBEAN SEA AND TROPICAL N ATLANTIC FROM 07N TO 19N BETWEEN 55W AND 64W... The previous cold front has become stationary from Haiti to just southeast of eastern Cuba and to inland central Belize. The front is expected to gradually dissipate through Thu. High pressure currently across the Gulf of Mexico will slide east- northeastward and build north of the area Thu night and Fri, with the associated pressure gradient increasing the trades. Northwest to north swell will continue to impact the Atlantic waters and Atlantic passages through the next few days. ...SW N ATLANTIC INCLUDING THE BAHAMAS... ...A Very Progressive Winter Type Pattern has taken shape across the Region... The previous cold front has become stationary from near 23N65W to the northwest coast of Haiti. The front will gradually dissipate through Thu afternoon. A cold front moved into the NW part of the area this morning and extends from near 31N73W to just northwest of the NW Bahamas as of 18Z this afternoon. This front is preceded and followed by mainly strong winds. The front will quickly move eastward across the waters north of 27N through early Thu and become stationary over the southeast waters by early Thu evening. It will be followed by weak high pressure that will move off the Carolinas. Yet another cold front will move into the region from the north, reaching as far south as 27N by Sat night and become stationary through Sun night. It will then dissipate Mon. Strong high pressure will build southward Sun, resulting in strong northeast to east winds and building seas north of this front. These conditions will diminish some Mon night. $$ .WARNINGS...Any changes impacting coastal NWS offices will be coordinated through AWIPS II Collaboration Chat, or by telephone: .GULF OF MEXICO...
