000 AGXX40 KNHC 220627 MIMATS Marine Weather Discussion NWS National Hurricane Center Miami FL 227 AM EDT Mon Oct 22 2018 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 0000 UTC, a cold front extends from South Florida to 27N91W where it becomes a warm front to a weak 1015 mb low over the NW Gulf near 26N95W. A stationary front then trails from the low to 20N97W. The low pressure will lift N toward the coast of Texas through Wed night, then east-northeastward across the N central waters through Thu night and the NE Gulf by Fri, dragging a new cold front across the SW Gulf. A tight pressure gradient between the low and strong high pressure building over the SE CONUS is now supporting fresh to strong winds N of the low and warm front, and also W of the stationary front over the western Gulf as a ridge has built across the eastern slopes of the Sierra Madre Mountains in Mexico. A recent scatterometer pass confirms the presence of these wind speeds. Winds are expected to slightly diminish late today through early Tue. Then, these winds are forecasted to increase again late Tue or Wed as the low pressure tracks northeastward toward the NE Gulf and northern Florida by Fri. ...CARIBBEAN SEA AND TROPICAL N ATLANTIC FROM 07N TO 19N BETWEEN 55W AND 64W... Fresh to strong NE winds are forecast to pulse in the Windward Passage and south of Hispaniola during the evening and night hours through tonight. Elsewhere, moderate to fresh trades will continue through early Wed, then diminish to the gentle intensity through Thu night. A tropical wave over the far eastern Caribbean will slowly move across the eastern Caribbean through Wed as it weakens. East to southeast gentle to moderate winds will follow the wave. ...SW N ATLANTIC INCLUDING THE BAHAMAS... As of 0000 UTC, a strong cold front extending from near Bermuda to south Florida will reach from near 28N65W to the Florida Keys this morning, then become stationary through the middle of the week. Fresh to strong winds and seas to near 10 ft are noted behind the front. These marine conditions will persist through night as strong high pressure slides eastward off the U.S. east coast. The high pressure and front will weaken Tue through early Thu allowing for winds to diminish and seas to subside. The pressure gradient is forecast to tighten beginning on Thu east of NE Florida between high pressure to the N across the eastern seaboard and low pressure that tracks northeastward from the Gulf of the Mexico to across northern Florida. $$ .WARNINGS...Any changes impacting coastal NWS offices will be coordinated through AWIPS II Collaboration Chat, or by telephone: .GULF OF MEXICO...
