The following information is based on satellite imagery, weather observations, radar, and meteorological analysis. Based on 0600 UTC surface analysis and satellite imagery through 0900 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from 10N85W to 09N92W to low pressure near 10N98W to 09N109W where it transitions to ITCZ. The ITCZ continues to 10N123W to 10N140W. Scattered moderate to isolated strong convection is noted within 120 nm north and 90 nm south of the ITCZ between 129W and 134W. ...DISCUSSION... OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Northwest swell prevails over the offshore waters off the western coast of the Baja California norte where seas are in the 8-11 ft range. Seas have subsided below 8 ft off the coast of Baja California Sur with seas in the 6-7 ft range. Elsewhere over the remainder of the offshore waters off the coast Mexico seas are in the 4 to 6 ft range, while seas of 1 to 3 ft are noted over the Gulf of California. Continued pulses of northwesterly swell will continue to push across the area through the remainder of the week and into the upcoming weekend. High pressure will build over the Great Basin of the United States through weeks end. This will bring fresh to near gale force northerly winds over the Gulf of California Friday night through Saturday night as a very tight pressure gradient sets up across the region. A cold front moving across the Gulf of Mexico will bring the next Gulf of Tehuantepec gap wind event early Thursday morning. A progressive pattern will help winds to veer rapidly over the southwest Gulf of Mexico and keep this gap wind event brief. Winds will reach advisory criteria Thursday morning, and will persist through the day Thursday before falling below advisory criteria Thursday evening. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Light to gentle winds and seas in the 3 to 5 ft range are noted north of 10N, with moderate to locally fresh southwest flow and combined seas of 3 to 5 ft south of 10N. Winds will occasionally pulse to moderate to fresh offshore of the Gulf of Papagayo during the overnight hours. REMAINDER OF THE AREA... High pressure of 1033 mb is centered northwest of the area near 37N146W. The pressure gradient between this area of high pressure and lower pressure in the vicinity of the ITCZ is supporting fresh to strong trades north of the ITCZ to near 28N and west of 125W. Combined seas of 8 to 11 ft prevails over this area. Continued pulses of northwesterly swell will maintain seas of 8 ft or greater over much of the area north of the ITCZ through the remainder of the week and into the weekend. $$ AL
