The following information is based on satellite imagery, weather observations, radar, and meteorological analysis. Based on 1200 UTC surface analysis and satellite imagery through 1550 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from the coast of Nicaragua near 12N87W to 10N100W to 08N120W. The ITCZ stretches from 08N120W to 08N130W and then from 08N136W to beyond 08N140W. A surface trough breaks the ITCZ along 132W. Scattered moderate convection is occurring from 04N to 09N E of 86W, and from 06N to 12N W of 124W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... A weakening cold front extending from the central Gulf of California SW to Punta Abreojos in the Baja California peninsula continue to support moderate to locally fresh NW winds along the Baja California offshore waters where recent altimeter data show seas in the 7 to 9 ft range in NW swell. Moderate to fresh NW winds are also in the Gulf of California with seas to 3 ft, highest winds and seas N of 29N. A plume of fresh to strong winds in the Tehuantepec region is decreasing to fresh winds this morning with seas remaining in the 5-7 ft range. Gentle to moderate NW winds are elsewhere in the SW Mexican offshore waters with seas of 5-6 ft in mixed SW and NW swell. For the forecast, the cold front moving across Baja California will continue to weaken as it slides SE and dissipate by Fri. The NW swell following the front will gradually subside, diminishing below 8 ft by Fri night. A new gap wind event with fresh to strong northerly is expected in the Gulf of Tehuantepec early Sun into Mon. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Scattered showers continue to affect the waters off NW Colombia, Costa Rica and Panama where moderate to occasionally fresh SW winds prevail with seas to 5 ft in SW swell. Elsewhere, light to gentle winds and seas of 3-5 ft prevail. For the forecast, moderate to locally fresh SW winds will prevail south of the monsoon trough through early Sat, before diminishing late Sat. Light to gentle variable winds will persist elsewhere. Slight to moderate seas can also be expected. REMAINDER OF THE AREA... Gentle to moderate NE to E winds and seas of 8 to 9 ft are across most of the open waters N of the monsoon trough/ITCZ and west of 116W. Elsewhere, moderate to locally fresh southerly winds are evident south of the monsoon trough and E of 105W. Seas are 4-6 ft in the waters described. In the remainder of the basin, moderate or weaker winds and moderate seas prevail. For the forecast, the aforementioned frontal boundary will devolve into a trough and dissipate by Fri. Moderate to locally fresh easterly winds will continue into early next week. Decaying swell will lead to subsiding seas of 8-9 ft today, with further diminishing seas into Fri. Looking ahead, the next set of long-period NW swell is expected to move into the far northwest part of the discussion area Sun. $$ Ramos
