The following information is based on satellite imagery, weather observations, radar, and meteorological analysis. Based on 1200 UTC surface analysis and satellite imagery through 1500 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from a 1011 mb low pressure located over northern Colombia near 10N74W to 06N80W to 07N87W to 07N99W. The ITCZ continues from 07N99W to 08N108W to 08N127W to 06N140W. Scattered moderate convection is noted from 04N to 07N between 78W and 84W, from 03N to 10N between 132W ans 136W, and from 10N to 19N W of 130W. A cluster of moderate to isolated strong convection is seen from 06N to 09N between 125W and 129W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Moderate to fresh NW to N winds are expected across the offshore waters of Baja California and N of Cabo San Lazaro over the next several days under the influence of a ridge. NW swell, with sea heights in the 8 to 11 ft are noted beyond the Revillagigedo Islands. Long period NW swell will continue to propagate across the area building seas up to 12-14 ft N of Punta Eugenia later today, and N of Cabo San Lazaro by Tue morning. Farther south in the Tehuantepec region, fresh to strong northerly winds and seas of 8-9 ft will prevail across the area through Tue night. These marine conditions will return again late on Thu as the next cold front moves across the Gulf of Mexico. Winds may briefly reach minimal gale force THu night into Fri, with seas building up to 10 ft. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, and WITHIN 750 NM OF ECUADOR... Fresh to strong NE-E winds will pulse in the Gulf of Papagayo region the next several nights, with seas building to 8 ft. Elsewhere, gentle to moderate winds and slight to moderate seas prevail across the region. Long period NW swell will continue to spread across the offshore waters of Central America, Colombia, and Ecuador over the next several days, but seas will remain below 8 ft. REMAINDER OF THE AREA... High pressure of 1025 mb located near 28N127W dominates the forecast waters N of 15N W of 110W. The pressure gradient between this area of high pressure and lower pressure in the vicinity of the ITCZ is supporting moderate to fresh trades particularly from 10N-20N W of 125W. Long period NW swells are propagating across most of the waters N of the equator and W of 110W, with seas of 8 to 12 ft, except 12 to 15 ft NW of a line from 30N122W to 21N140W. Additional pulses of NW swell will reach the NW corner of the forecast region on Wed. On this day, seas of 8 ft or greater will affect most of the waters N of 03.4S and W of 95W. $$ GR
