000 AXPZ20 KNHC 120853 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 1005 UTC Mon Jun 12 2023 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 0840 UTC. ...TROPICAL WAVES... A tropical wave is along 95W north of 01N, moving west at 10 kt. No significant convection is evident near the wave axis. A tropical wave is analyzed along 111W from 02N to 12N, moving west at 10 to 15 kt. No significant convection is evident near the wave axis. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from 11N86W to 11N100W to 08N115W. The ITCZ continues from 08N115W to 06N130W to beyond 07N140W. Scattered moderate convection is evident from 08N to 10N between 96W and 99W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Fresh to locally strong SW gap winds over the northern Gulf of California are diminishing as deep low pressure over the lower Colorado River valley weakens. A surface ridge nosing into Baja California Sur is allowing moderate to fresh NW winds to funnel along the coast between Cabo San Lazaro and Cabo San Lucas with 4 to 6 ft seas in mixed S and NW swell. Moderate winds are elsewhere in the Gulf of California and in the S and SW Mexican offshore waters. Seas are 4 to 5 ft, except 1 to 3 ft in the Gulf of California. For the forecast, fresh to strong SW gap winds pulsing over the northern portion of the Gulf of California will diminish through early this morning. Farther south, a ridge will persist between Baja California Sur and the Revillagigedo Islands through mid- week, supporting fresh winds along the coast of Baja California Sur mainly at night, and fresh to occasionally strong winds off Cabo San Lucas. Gentle winds will persist elsewhere. ...OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Light and variable winds are noted over the offshore forecast waters of Central America and Colombia while gentle to moderate southerly winds are seen mainly south of 04N, including the waters between Ecuador and the Galapagos Islands. Seas are 4-5 ft in SW swell across the region, except for 4-7 ft between the coast of Ecuador and the Galapagos Islands. For the forecast, the weak pressure gradient will remain in place across the region supporting mainly light to gentle variable winds across the Central America offshore waters, except for developing moderate to fresh NE gap winds in the region of Papagayo Tue night through Wed night. Moderate, long- period SW swell will persist mainly south of 10N building seas to 7 or 8 ft between Ecuador and the Galapagos Islands through mid week. ...REMAINDER OF THE AREA... A trough extends from 28N120W to 25N130W, breaking up the subtropical ridge normally in place over this area. This pattern is supporting light breezes with 3 to 5 ft combined seas north of 20N between 120W and 130W. Moderate to locally fresh trade winds are in place elsewhere north of 08N west of 120W, with 6 to 8 ft combined seas. Gentle to moderate southerly flow is evident elsewhere with 5 to 7 ft combined seas in southerly swell, except to 8 ft south of the equator. For the forecast, little change in the pattern or impacts on winds and seas through mid week, except for slightly higher trade wind flow north of 08N and west of 130W as high pressure gradually builds north of the area. $$ Christensen
