  Tropical Weather Discussion for the eastern Pacific Ocean from
  03.4S to 30N, east of 120W including the Gulf of California, and
  from the Equator to 30N, between 120W and 140W. The following
  information is based on satellite imagery, weather observations,
  radar, and meteorological analysis.
  
  Based on 0600 UTC surface analysis and satellite imagery through
  0915 UTC.
  
  ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH...
  
  A trough extends from 08N87W to 03N96W to 01N108W. The ITCZ
  extends from 02N121W to 04N133W and to beyond 04N140W. To the S,
  a second tough is noted from 03.4S92.5W to 01S101W to 04N110W to
  03N115W to 02S120W. Scattered moderate convection is seen from
  04.5N to 10N between 127W-140W, and within 30 nm of the second
  trough between 93W-95W.
  
  ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO...
  
  Strong high pressure of 1038 mb is centered well to the NW of
  the area near 38N138W. A broad ridge extends southeastward from
  the high to near the Revillagigedo Islands. The pressure gradient
  between this ridge and a meandering surface trough over the Gulf
  of California extending to NW Mexico is producing gentle to
  moderate NW to N winds offshore the Baja California waters. Seas
  are 6 to 8 ft with these winds, except for higher seas of 7 to 11
  ft in NW swell over the outer offshore waters N of Cabo San
  Lazaro and lower seas of 5 to 7 ft over the waters from Cabo San
  Lucas. Moderate to fresh NW winds are over the central Gulf of
  California as noted in an overnight scatterometer altimeter pass
  over that part of the Gulf. The same pass indicated gentle to
  moderate winds elsewhere over the Gulf, including the entrance to
  the Gulf. Slight to moderate seas prevail. Elsewhere over the
  Mexican offshore waters, including the Gulf of Tehuantepec,
  generally light winds and moderate seas in S to SW swell are
  present.
  
  For the forecast, the aforementioned ridge will continue to
  dominate the offshore forecast waters of Baja California through
  this morning generally supporting gentle o moderate NW to N
  winds. A broad area of low pressure is expected to form just
  offshore Baja California Norte today, then shift slowly eastward
  into early next week while dissipating. The tightening pressure
  gradient between the low center and the ridge to the W will
  promote fresh to locally strong W to NW winds and building seas
  to around 8 ft across the outer forecast waters N of Punta
  Eugenia on Sun. Gentle winds along with moderate seas in SW swell
  are expected in the Gulf of Tehuantepec through the forecast
  period.
  
  ....OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA,
  AND WITHIN 750 NM OF ECUADOR...
  
  Fresh to strong NE to E winds are in the Gulf of Papagayo region
  while gentle to moderate N winds are in the Gulf of Panama. An
  overnight altimeter satellite pass captured seas in the general
  range of 4 to 6 ft in the Gulf of Papagayo region. Slightly lower
  seas of 3 to 4 ft are in the Gulf of Panama. The latest
  scatterometer satellite data passes reveal mostly light to gentle
  winds elsewhere. Latest altimeter satellite data passes reveal
  seas of 3 to 5 ft in long-period S to SW swell elsewhere.
  
  For the forecast, fresh to strong winds are expected in the
  Papagayo region nightly and into the mornings through Tue as high
  pressure remains N of the region. Gentle to locally moderate N
  winds are forecast in the Gulf of Panama into next week. Mainly
  light to gentle winds will prevail elsewhere through early next
  week. Looking ahead, significant cross-equatorial SW swell is
  expected to reach the offshore waters between Ecuador and the
  Galapagos Islands early next week, building seas to around 8 ft,
  except in the lee of the Galapagos Islands.
  
  ...REMAINDER OF THE AREA...
  
  Strong high pressure of 1038 mb is centered well to the NW of
  the region near 38N138W. Associated broad ridging covers the
  waters N of about 15N and W of 112W. The related gradient is
  sustaining fresh to strong N to NE winds N of 25N between 130W
  and 132W as seen in the latest scatterometer satellite data
  passes over that part of the area. Seas are 8 to 11 ft with these
  winds, with the highest of the seas N of 28N between 121W and
  128W. A couple of overnight altimeter satellite data passes
  indicated such seas. Fresh to strong NE to E trades are confined
  to the western part of the area from 18N to 28N W of 130W. Seas
  with these winds are peaking to near 11 ft. Elsewhere, winds are
  of moderate or weaker speeds. Seas across the remainder of the
  open waters are 4 to 6 ft in mixed swell, except for higher seas
  of 6 to 9 ft in NE swell elsewhere from 07N to 30N W of 130W.
  
  For the forecast, the aforementioned strong high pressure will
  continue to dominate the majority of the western and central
  waters N of 15N and W of 112W through the weekend while it
  weakens some as a cold front approaches from the NW. The cold
  front is expected to stay N of 30N during this time. Trades over
  the western half of the area will weaken to mostly fresh speeds
  also during this time, and the NE swell will slowly decay
  allowing for the seas there to subside to 8 ft by early Sun
  evening.
