Expect NE to E gale-force winds in 24 hours, on Monday night, and sea heights ranging from 10 feet to 13 feet, from 11N to 13N between 73W and 76W. The gale- force winds are forecast to last for 12 hours or so until Tuesday morning, to be at less than gale-force for the next 12 hours, and then return to gale-force again at 48 hours on Tuesday night. Please, read the HIGH SEAS FORECAST, MIAHSFAT2/ FZNT02 KNHC, for more details. ...TROPICAL WAVES... An Atlantic Ocean tropical wave is along 25W/26W from 13N southward. Scattered moderate to isolated strong rainshowers are from 04N to 07N between 27W and 32W. An Atlantic Ocean tropical wave is along 43W/44W from 14N southward. Scattered moderate to strong rainshowers are within 60 nm to 75 nm on either side of 05N41W 08N42W 09N45W 10N51W. An Atlantic Ocean tropical wave is along 58W, from 14N southward. Scattered moderate to strong rainshowers are from 09N to 11N between 57W and 62W. A Caribbean Sea tropical wave is along 69W from 18N southward. The wave is moving through the area of an upper level trough. Isolated moderate rainshowers cover the area that is between 60W and 72W. A Caribbean Sea tropical wave is along 81W/82W, from 19N southward. No significant deep convective precipitation is apparent with this wave at this moment. ...MONSOON TROUGH/ITCZ... The monsoon trough passes through the coastal plains of Guinea, just to the east of the border area with Guinea-Bissau, near 11N15W, to 08N18W and 07N22W. The ITCZ continues from 07N22W to 06N28W 06N42W 07N53W and to 07N56W. Scattered moderate to strong rainshowers are from 04N to 07N between 35W and 38W. Isolated moderate to locally strong rainshowers are elsewhere, away from the tropical waves, from 10N southward from 60W eastward. GULF OF MEXICO... Broad upper level cyclonic wind flow spans the Gulf of Mexico. Isolated moderate to locally strong rainshowers are spread through the open waters of the Gulf of Mexico. A surface ridge extends from the NE corner of the Gulf of Mexico, into the west central sections, into the SW corner of the Gulf of Mexico. High pressure will prevail across the forecast waters through Friday. CARIBBEAN SEA... An upper level trough passes through the Atlantic Ocean near 24N56W, beyond the NE part of the Caribbean Sea near 18N64W, continuing toward La Peninsula de la Guajira of northern Colombia. Rainshowers are possible within 120 nm on either side of the trough. The tightening surface pressure gradient, between the Atlantic Ocean ridge and the Colombia low pressure, will allow the wind speeds to pulse to minimal gale force off the coast of Colombia and Venezuela each night starting on Monday night. Fresh to strong winds are expected to pulse in the Gulf of Honduras at night. ATLANTIC OCEAN... An upper level trough is moving through the easternmost sections of the Gulf of Mexico to Florida. Remaining isolated moderate to locally strong rainshowers cover the areas from the Windward Passage, northwestward across Cuba, to parts of the Bahamas and Florida, including the surrounding waters, from 32N southward from 74W westward. A stationary front is along 33N50W 31N58W 32N67W. Isolated moderate rainshowers are from 26N to 34N between 60W and 70W. An upper level trough is along 30N48W 24N56W, beyond the NE part of the Caribbean Sea near 18N64W. A surface trough is along 28N50W 26N56W. Isolated moderate rainshowers are within 300 nm on either side of the trough. An upper level cyclonic circulation center just started to move to the east, away from the Azores. Upper level cyclonic wind flow covers the Atlantic Ocean, from 22N northward from 40W eastward. A cold front passes through 32N24W to 29N30W, to 28N34W and 29N40W. Rainshowers are possible from 26N northward between Africa and 40W. A surface trough will move slowly eastward off NE Florida from Tuesday through Thursday.
