186 AXPZ20 KNHC 081459 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 1605 UTC Mon Jul 8 2024 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 1200 UTC surface analysis and satellite imagery through 1500 UTC. ...TROPICAL WAVES... A tropical wave extends north of 02N along 89W moving west at 10 kt. No significant deep convection is present near the tropical wave this morning. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from the coast of the Costa Rica/Nicaragua border near 11N86W to to 10N134W. The ITCZ extends from 10N134W to beyond 08N140W. Scattered moderate to isolated strong convection is active from 08N-16N between 95W-100W and from 07N-12N between 105W-123W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... A trough near of Guadalupe Island is breaking up the subtropical ridge across the region, resulting in light to gentle breezes across the entire Mexican offshore and Gulf of California waters. Seas are 4-6 ft over the Pacific waters and 1-2 ft over the Gulf of California. Clusters of showers and thunderstorms are noted across the Gulf of Tehuantepec. For the forecast, aside from SE winds pulsing to fresh over the N Gulf of California through tomorrow, moderate or weaker winds will persist through Thu across the Mexican offshore waters. Looking ahead, a Gulf of Tehuantepec gap wind event may begin Fri with strengthening winds and building seas. ...OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... South of the monsoon trough, winds are S to SW gentle to moderate. North of the monsoon trough, the winds are light to gentle. Seas across the waters are 4-7 ft in S swell. For the forecast, quiescent marine conditions will prevail over the Central American and Equatorial waters for the next several days. Looking ahead, a gap wind event may begin off N Central America Fri with strengthening winds and building seas. ...REMAINDER OF THE AREA... A 1023 mb high pressure is centered near 32N140W. The gradient between the high and a trough near Guadalupe Island is supporting moderate to fresh NE winds north of 20N west of 127W. Combined seas are 6-7 ft in this area. Moderate NE trade winds and 6-7 ft combined seas are also evident south of the high pressure from 10N-20N west of 130W. Gentle to moderate winds and 5-7 ft seas in mixed N and S swell dominate the remainder of the basin. For the forecast, the trough near Guadalupe Island will persist through late in the week. Expect moderate to fresh N to NE winds and 5-8 ft seas between this trough and higher pressure to the northwest through mid week, mainly north of the 20N and west of 125W. The tradewinds will be weaker than usual with only gentle to moderate NE winds between 10N-22N through mid week. Looking ahead, large N to NE swell should move southward across the 30N border west of 120W beginning on Fri. $$ Landsea
