Please read the High Seas Forecast, listed under the AWIPS/WMO headers HSFAT2/FZNT02 KNHC, or visit our website for more details at https://www.nhc.noaa.gov/text/MIAHSFAT2. ...MONSOON TROUGH/ITCZ... The monsoon trough passes through the coastal sections of Liberia near 06N10W and extends to 02N17W. The ITCZ continues from 02N17W to the coast of Brazil near 02S42W. Scattered moderate isolated strong convection is present from 02S-02N between 10W and 23W and more scattered shower activity elsewhere along the ITCZ near Brazil. GULF OF MEXICO... A 1016 mb low is centered over the NW Gulf of Mexico near 29N96W. A surface trough extends south from the low to near South Texas near 25N97W. Overcast low stratus clouds cover the far western Gulf with areas of fog along the Texas coast and western Louisiana. In some of these areas, where light showers are occurring off the coast of Texas, visibilities of 1 to 2 miles are being reported. Gentle to moderate winds are across the basin. A surface trough is also observed along the Yucatan Peninsula near 22N90W to 18N91W. No significant convection is noted with this trough. High pres will build across the northern Gulf coast Mon, shifting E ahead of a cold front entering the NW Gulf early Tue morning. Strong northerly winds will follow the front, reaching minimal gale force across the W central Gulf Tue afternoon. See Special Features above for more details on the Gale Warning. Winds will diminish Wed afternoon as the front pushes SE of the basin. High pres and return flow will prevail across the basin Thu and Thu night. Another cold front will move into the northern Gulf Fri night. CARIBBEAN SEA... Relatively dry air covers most of the Caribbean basin. However, isolated low-topped showers continue across much of the basin. Scatterometer passes show fresh to strong northeast winds in the Windward Passage and south of Hispaniola. Strong to gale force winds are occurring near northern Colombia coast. Moderate to fresh trade winds are elsewhere over the Caribbean basin. High pres NE of the area will maintain fresh to strong trades across the central Caribbean, pulsing to gale force at night NW of the coast of Colombia through Tue night. Trades will weaken slightly on WEd as an approaching cold front weakens the ridge. The front will stall near the Yucatan Channel early Wed, then siddipate. Fresh to strong trades will be confined to the S central Caribbean for the end of the week. ATLANTIC OCEAN... A cold front extends from 31N39W to 26N70W, continuing as a dissipating stationary front to near Melbourne Florida. Isolated showers with overcast low stratus clouds are in the proximity of both boundaries. Farther E, a stationary front is 31N27W to 22N39W. Scattered showers are in the vicinity of the front. A stalling front along 26N-27N will gradually dissipate through tonight. High pres building N of the area will support moderate to fresh E to SE winds through Wed, with locally strong winds pulsing each night off the coast of Hispaniola through Tue night. NE swell in excess of 8 ft E of the Bahamas will subside by early Tue. Southerly winds will increase off NE Florida by late Tue ahead of a cold front moving off the Florida coast Tue night. The front will reach from Bermuda to N central Cuba Wed night, dissipating over the SE waters Thu and Thu night. Return flow under high pres will prevail for the end of the week ahead of the next possibly strong cold front. For additional information please visit http://www.hurricanes.gov/marine $$ MTorres
