000 AGXX40 KNHC 190749 MIMATS Marine Weather Discussion NWS National Hurricane Center Miami FL 349 AM EDT Mon Oct 19 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... A surface ridge will continue building across the Gulf waters. The pressure gradient will tight across the eastern Gulf beginning tonight, resulting in fresh to strong easterly winds and building seas. Gentle to moderate winds will prevail elsewhere. ...CARIBBEAN SEA AND TROPICAL N ATLANTIC FROM 07N TO 19N BETWEEN 55W AND 64W... A tropical wave moving across the W Caribbean will reach the Yucatan Peninsula by Tue morning enhancing winds and convection over the region. A broad area of low pressure is likely to form in a couple of days over the southwestern Caribbean. Some gradual development of this system is possible late this week as it moves slowly northwestward or north- northwestward over the area. ...SW N ATLANTIC INCLUDING THE BAHAMAS... A weakening stationary front extending from 31N73W to the Straits of Florida will dissipate on Mon. A non-tropical low pressure system located about 600 miles southeast of Bermuda is poorly organized. Environmental conditions remain conducive for development, and a subtropical depression or storm is very likely to form during the next day or so while the low meanders well to the southeast of Bermuda. The pressure gradient between high pressure to the north and the low will increase winds and seas across the NE waters beginning tonight. Swell generated by this system will propagate across the waters E of the Bahamas beginning on Mon, and reach the Atlantic/Caribbean passages on Tue. $$ .WARNINGS...Any changes impacting coastal NWS offices will be coordinated through AWIPS II Collaboration Chat, or by telephone: .GULF OF MEXICO...
