216 AGXX40 KNHC 200755 MIMATS Marine Weather Discussion NWS National Hurricane Center Miami FL 355 AM EDT Wed Mar 20 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 cold front extends through the Straits of Florida to a 1014 mb low pressure located near 23N83W to the NE Yucatan Peninsula. A tight pressure gradient along Florida and the NE gulf support NE strong to near gale force winds in the SE basin S of 25N. The front will shift SE and exit the region by this afternoon. High pressure will then dominate the entire Gulf through Sun. ...CARIBBEAN SEA AND TROPICAL N ATLANTIC FROM 07N TO 19N BETWEEN 55W AND 64W... Low pressure associated with a frontal system in the SW N Atlc is allowing for a relaxed pressure gradient in the south-central Caribbean. However, fresh to strong winds are expected to pulse at night within 90 nm off the coast of Colombia mainly due to the nocturnal drainage flow. Fresh to strong winds are also possible in the Gulf of Venezuela. Otherwise, the tail of a cold front extends from western Cuba SW to just N of Belize. The front will move SE and stall from central Cuba to NE Honduras adjacent waters by Thu morning and dissipate at night. Gentle to moderate winds will dominate across the remainder basin through Sun. ...SW N ATLANTIC INCLUDING THE BAHAMAS... A stationary front extends from 30N62W to 27N68W to a low pressure center near 26N74W then transitions to a cold front that continues to 23N80W into the NW Caribbean. The low will gradually shift NE dragging the cold front SE to the southern Bahamas by this evening. The front will then stall and weaken before dissipating by Thu night. Strong to minimal gale force winds are expected across the NW semicircle of the low center this morning through early Thu. NE swell associated with the front will propagate across the northern waters through Thu. However, swell associated with a reinforcing cold front will prevail through Sun. This second front will extend from near 25N65W to north-central Dominican Republic by Fri evening. $$ .WARNINGS...Any changes impacting coastal NWS offices will be coordinated through AWIPS II Collaboration Chat, or by telephone: .GULF OF MEXICO...
