000 AXPZ20 KNHC 112153 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 2205 UTC Sat May 11 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 1800 UTC surface analysis and satellite imagery through 2135 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from 11N86W to a 1011 low pres near 10N98W and to 08N111W. The ITCZ continues from 08N111W to beyond 05N140W. Scattered moderate to isolated strong convection is present north of 02N and east of 92W. Similar convection is also noted from 05N to 14N and between 95W and 110W, and from 02N to 08N and between 111W to 133W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... The region remains under the influence of a broad subtropical ridge located well NW of the Mexican offshore waters. A recent scatterometer satellite pass indicate that moderate to fresh NW winds are occurring in the offshore waters of Baja California. Seas in these waters are 5-7 ft. Elsewhere, including the Gulfs of California and Tehuantepec, satellite-derived wind data show light to gentle winds. Slight to moderate seas are prevalent in the area described. For the forecast, moderate to locally fresh NW winds will prevail off the Baja California waters through the middle of next week. Northwest swell will maintain seas to near 7 ft tonight into early Sun before gradually subsiding to 6 ft or less through early next week. Seas will build again to near 7 ft in the far NW waters by midweek. Gentle to locally moderate winds and moderate seas are expected elsewhere across the open offshore waters of Mexico through the middle of next week. ...OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Latest satellite imagery show scattered showers and isolated thunderstorms affecting the nearshore and offshore waters of Central America and NW Colombia, especially north of 02N and east of 92W. Scatterometer data indicate that fresh to strong winds are found with the strongest storms. Elsewhere, gentle to moderate winds are found south of the monsoon trough and light to gentle winds north of the monsoon trough. Southerly swell is producing seas in the 5-7 ft range between Colombia and the Galapagos Islands, with seas of 3-5 ft elsewhere. For the forecast, gentle to moderate S-SW winds are expected south of the monsoon trough through the middle of next week. Southerly swell moving through the regional waters will support seas of 6-7 ft S of the Galapagos Islands through early Mon. Elsewhere, light to gentle winds will prevail with moderate seas of 6 ft or less. ...REMAINDER OF THE AREA... A broad subtropical ridge centered well north of the area forces moderate to locally fresh easterly winds from 06N to 22N and west of 115W. Seas in these waters are 6-8 ft. Moderate to occasionally fresh southerly winds and seas of 6-8 ft are found south of the monsoon trough / ITCZ and between 96W and 125W. The satellite- derived wind data also depict strong winds associated with the strongest convection. Elsewhere, light to gentle winds and moderate seas prevail. For the forecast, moderate trade winds and moderate seas are expected in the trade wind zone N of the ITCZ to near 20N and W of 120W through Sun, before seas subside slightly through early next week. $$ Delgado
