000 AGXX40 KNHC 260729 MIMATS Marine Weather Discussion NWS National Hurricane Center Miami FL 229 AM EST Sun Jan 26 2020 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 ridging over the Gulf will shift eastward through Mon as low pressure develops near the Texas coast by this afternoon. The low pressure, along with a trailing cold front, will track eastward to the NE Gulf through Mon afternoon while weakening, then across Florida on Tue. Another weak low pressure area will move into the NW Gulf Tue night, slowly move east- southeastward through Wed night, then retreat to the northwest thereafter. ...CARIBBEAN SEA AND TROPICAL N ATLANTIC FROM 07N TO 19N BETWEEN 55W AND 64W... A weakening stationary front analyzed to the south of Puerto Rico and the Virgin Islands as of 06Z will dissipate this morning. A weak trough along 68W and south of 15N is producing isolated showers near it. The trough will gradually move westward in the SW Caribbean through early Tue while dissipating. Otherwise, relatively weak high pressure across the region will maintain rather quiet conditions over the forecast waters allowing for generally gentle to moderate winds, except for fresh winds ear the coast of Colombia during the afternoons and night time hours through Wed. These winds increase to fresh to strong speeds Thu night and to mainly fresh speeds over the remainder of the area as stronger Atlantic high pressure builds southeastward while it shifts eastward. Expect for waveheights to build to maximum of about 8 ft near the coast of Colombia on Thu night. ...SW N ATLANTIC INCLUDING THE BAHAMAS... A weak cold front extending from near 31N73W to the central Bahamas and to western Cuba will reach from near 31N72W to west- central Cuba early this afternoon, then from near 31N69W to 26N73W where it begin to dissipate to central Cuba by early tonight. The remaining cold front portion north of 26N will move east of the forecast waters late tonight into early Mon. A series of cold fronts will move across the area during the upcoming week, with the main impacts related to winds and building waveheights expected north and northeast of the Bahamas. However, since a couple of these fronts will be associated to weak low pressure energy that will translate eastward from the Gulf of Mexico to across Florida and the western part of the area, expect for related atmospheric instability to result in increasing chances for scattered showers and a few thunderstorms across the waters mainly around and near the Bahamas Mon through Tue night. Similar activity may possibly occur again on Thu or before. With regards to waveheights, three sets of north to northeast swell will propagate through the NE portion of the basin during this upcoming week. The most significant one of these is expected Tue into early Wed with waveheights in the range of 8-10 ft. $$ .WARNINGS...Any changes impacting coastal NWS offices will be coordinated through AWIPS II Collaboration Chat, or by telephone: .GULF OF MEXICO...
