000 AXPZ20 KNHC 290721 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 1005 UTC Mon May 29 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 0700 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from the coast of Costa Rica near 09N84W to 09N108W to 07N129W. The ITCZ continues from 07N129W to 06N140W. Scattered moderate to isolated strong convection extends from 02N to 13N E of 121W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Moderate NW winds prevail W of the Baja Peninsula. Seas are 4 to 6 ft in S swell. Gentle winds are noted in the Gulf of California with slight seas. Light to gentle winds prevail across the offshore waters of the southern Mexico coast with moderate seas. Smoke from agricultural fires may be impacting waters offshore Chiapas. For the forecast, the gradient between subtropical high pressure in the Pacific and a surface trough near the Gulf of California will persist through mid-week. Winds are expected to pulse to fresh during the overnight and early morning hours west of the Baja Peninsula during this time. Fresh to strong S to SW gap winds will briefly occur in the northern Gulf of California each night through the forecast period. Seas of 4-6 ft across the Mexico offshore waters will continue through most of the week. ...OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Across the offshore waters of Central America, winds are light to gentle. South of the monsoon trough, southerly light to gentle winds are noted. Gentle to locally moderate S winds prevail in the Ecuador and Galapagos Islands offshore waters. Seas have began to subside across the waters and now range 7-9 ft in southerly swell. Scattered thunderstorms noted throughout the waters. Smoke from agricultural fires in Central America may be restricting visibility N of Nicaragua. For the forecast, light to gentle winds prevail north of the monsoon trough. Gentle to locally moderate SW monsoon winds are expected in the South American offshore zones. Moderate S to SW long period swell will dominate. Smoke from agricultural fires in Central America may occasionally restrict visibility for offshore waters of Nicaragua northward. ...REMAINDER OF THE AREA... High pressure of 1033 mb located northwest of the area near 39N157W extends a ridge over the eastern Pacific. The associated pressure gradient is supporting gentle to moderate anticyclonic flow across the majority of the area. Gentle to locally moderate southerly winds prevail south of the monsoon trough/ITCZ to the Equator. Seas range 4-7 ft across most of the waters. For the forecast, no major changes are expected. The ridge will continue to dominate the region north of 10N and west of 110W through mid-week. Mainly moderate NE trade winds will persist across the southern periphery of the ridge, especially west of 120W, and some locally fresh E winds are expected just N of the ITCZ. A new set of long- period S to SW swell will approach the eastern tropical Pacific Wed. $$ KONARIK
