The following information is based on satellite imagery, weather observations, radar, and meteorological analysis. Based on 0000 UTC surface analysis and satellite imagery through 0300 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... A surface trough extends from 09N78W to 05N99W. The ITCZ continues from 05N99W to 04N140W. No significant convection is associated with the ITCZ. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... A broad ridge associated with strong high pressure near 41N143W dominates the offshore waters west of Baja California to Cabo Corrientes, producing gentle to moderate NW winds, except fresh winds near the coast of Cabo San Lucas. 7 to 9 ft seas prevail across the waters west of Baja California, which will gradually subside to 6-7 ft by Thu night. A weakening cold front will approach the northern Gulf of California Thu afternoon, with strong SW winds developing ahead of the boundary Thu through Fri morning. Winds near 30 kt with gusts to gale force are expected across north portions of the Gulf Thu afternoon and evening. Farther south, no gap wind events are expected in the Gulf of Tehuantepec through Sun. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, and WITHIN 750 NM OF ECUADOR... Scatterometer data earlier today showed mostly gentle to moderate winds across the forecast waters. Seas across the regional waters are estimated to be in the 3 to 5 ft range. Fresh to strong winds are expected in the Gulf of Papagayo region Fri night through Mon night. Mainly light to gentle winds are expected elsewhere. Moderate long-period SW swell will prevail across the region the next several days. REMAINDER OF THE AREA... High pressure centered north of the forecast area near 41N143W is supporting fresh trade winds north of the ITCZ and west of around 120W. The areal extent of these winds will retract tonight through Thu as the high pressure shifts northward. Seas are generally 7-10 ft in a broad mix of swell across this area. Long period northerly swell dominates most of the forecast waters west of 110W, while long period cross-equatorial SW swell continues to propagate into the area east of 110W, reaching the coastal waters of Mexico, Central America, Colombia and Ecuador. Additional pulses of SW swell will continue across the region through the weekend. $$ Mundell
