  ...SPECIAL FEATURES...
  
  Caribbean Gale Warning: The gradient between an Atlantic high
  pressure ridge and lower pressure over Colombia will continue to
  induce strong winds over the south-central Caribbean Sea, pulsing
  to gale-force winds at night near the coast of Colombia through
  Tue night. Seas are forecast to peak around 10-12 ft each morning
  in the vicinity of 12N76W.
  
  Atlantic large swell event: A storm force low over the N Atlantic
  has generated a large long-period NW swell. The associated cold
  front is expected to propagate into the waters E of 55W tonight.
  Seas of 12 to 14 ft will propagate into the northern waters in
  the wake of the front, N of 30N between 40W and 50W tonight. Seas
  will peak near 16 ft over the waters N of 30N between 35W and 50W
  Sun night. The swell will propagate southeastward, reaching as
  far south as 25N early Mon before subsiding. Seas over the
  discussion waters associated to this swell will subside below 12
  ft Tue.

  ...MONSOON TROUGH/ITCZ...
  
  The monsoon trough passes through the coastal plains of Sierra
  Leone near 07N12W to 00N29W. The ITCZ continues from 00N29W to
  02S43W. Scattered moderate convection is noted from 00N to 05N
  and E of 28W. Scattered showers are noted within 100 nm N of the
  ITCZ mainly W of 35W.
  
  GULF OF MEXICO...
  
  Surface ridging prevails across the Gulf waters. A cold front has
  entered the NW Gulf area, extending along the Texas coastline. A
  pre frontal trough is analyzed from 28N94W to 27N96W. Fresh to
  strong winds are noted N of the Yucatan peninsula as well as off
  Veracruz, Mexico. Gentle to moderate winds are noted elsewhere.
  Seas are in the 5-7 ft range N of the Yucatan peninsula, 4-6 ft W
  of 90W, and 2-4 ft elsewhere.
  
  For the forecast, the surface ridge extending will slowly shift
  southward through late Mon. Fresh to strong winds will pulse off
  the Yucatan peninsula during the evening hours through the period.
  The cold front along the NW corner of the basin will move farther
  southeastward before dissipating tonight. Another cold front will
  enter the NW Gulf late Mon night and move slowly southeastward.
  This front will reach from central Florida to NE Mexico by late
  Tue, and from the southeastern Gulf to the Bay of Campeche by late
  Wed. Moderate to fresh northeast to east winds will follow behind
  the front. Fresh east to southeast winds develop in the NW Gulf
  on Wed.
  
  CARIBBEAN SEA...
  
  Please read the Special Features section for details on a Gale
  Warning in the south-central Caribbean Sea.
  
  Strong to near-gale NE winds are noted within 90 nm of the coast
  of Colombia. Fresh to strong winds are noted elsewhere over the
  central Caribbean and Gulf of Honduras. Moderate to fresh winds
  prevail over the eastern Caribbean. Gentle to moderate winds are
  elsewhere. Seas are in the 7-10 ft range over the south central
  Caribbean. Elsewhere, seas of 4-6 ft prevail, except in the lee of
  Cuba where seas are in the 3-4 ft range, and 6-7 ft over the Gulf
  of Honduras.
  
  For the forecast, the pressure gradient between the Atlantic ridge
  and lower pressure over Colombia will support strong winds over the
  south-central Caribbean Sea, pulsing to gale-force winds at night
  near the coast of Colombia through Tue night. Winds will pulse to
  strong in the Windward Passage and south of Hispaniola through
  the weekend. Strong trade winds will prevail over the Gulf of
  Honduras into early next week. Fresh trade winds will prevail
  elsewhere across the eastern and central Caribbean through the
  period.
  
  ATLANTIC OCEAN...
  
  Refer to the section above for details on the significant swell
  event expected to begin tonight.
  
  High pressure of 1023 mb is centered near 30N62W. Light to gentle
  winds are in the vicinity of the high center. Moderate to fresh
  winds are found off the coast of northern Florida. Gentle to
  moderate winds prevail elsewhere. Seas in the 8-10 ft range are
  noted N of 25N between 30W and 45W. Elsewhere, seas of 5-7 ft
  prevail, except 4-5 ft in the vicinity of the high center.
  
  For the forecast W of 55W, high pressure will prevail over the
  area through the weekend, then shift slightly southward next week
  as a cold front moves across the waters north of the Bahamas.
  Fresh to strong winds will be in the vicinity of the cold front
  along with building seas. Winds are expected to reach near gale-
  force on either side of the front north of 29N the middle of next
  week as the front reaches from near 31N60W across central Bahamas
  to east-central Cuba.
