000 AXPZ20 KNHC 310852 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 1005 UTC Wed May 31 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 0800 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from 10N83W to 11N100W to 06N127W. The ITCZ continues from 06N127W to 03N140W. Scattered moderate to isolated strong convection is noted from 01N to 12N E of 104W. Scattered moderate convection is noted from 06N to 10N between 115W and 126W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Moderate to fresh NW winds prevail within 120 nm of the Baja California coast in the offshore waters, with gentle to moderate winds further to the W. For the Gulf of California, light winds prevail, except for some locally fresh SW winds in portions of the northern Gulf. Gentle to moderate NW winds are noted elsewhere over the open waters off Mexico. Seas are 5 to 6 ft in S swell over the open waters off Mexico, except to 7 ft off of Cabo San Lucas. Seas of 2-4 ft are noted over the northern Gulf of California, and 1-2 ft are elsewhere over the Gulf, except the entrance to the Gulf where seas of 4-5 ft are noted. For the forecast, the pressure gradient between subtropical Pacific high pressure centered N of the Hawaiian Islands and a surface trough in the Gulf of California will support pulses of fresh winds from the evening through early morning hours across the waters west of the Baja Peninsula. Fresh to strong S to SW gap winds will briefly occur in the northern Gulf of California each night into Thu. Moderate seas will continue through the week across the Mexico offshore waters. ...OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Gentle to moderate S winds prevail in the Ecuador and Galapagos Islands offshore waters. Mainly gentle winds prevail elsewhere. Seas are in the 4-6 ft range in mostly cross equatorial SW swell. For the forecast, light to gentle winds will prevail north of the monsoon trough for the next several days. Gentle to moderate SW monsoon winds are expected in the South American offshore zones. Moderate S to SW cross equatorial swell will dominate regional seas through Sat before large SW swell gradually builds into the area waters Sat night into the start of next week. ...REMAINDER OF THE AREA... High pressure prevails over the northern waters, centered on a 1033 mb Pacific high located N of the Hawaiian Islands near 40N. The pressure gradient between this area of high pressure and lower pressure in the vicinity of the ITCZ is supporting moderate to fresh winds N of the ITCZ to near 16N and W of 120W. Gentle to moderate S to SW winds are noted S of the monsoon trough and E of 115W. Light to gentle winds are noted elsewhere. Seas range from 5-7 ft S of 15N and 4-6 ft N of 15N. For the forecast, no major changes are expected. The ridge will continue to dominate the region north of 10N and west of 110W through Fri. Mainly moderate NE trade winds will persist across the southern periphery of the ridge, especially west of 120W, and some fresh E winds are expected just N of the ITCZ. A new pulse of large cross equatorial SW swell will reach the eastern tropical Pacific on Sat. $$ KONARIK
