174 AXPZ20 KNHC 271555 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 1605 UTC Wed Nov 27 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 1530 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from 10N86W to 07N99W. The ITCZ continues from 07N99W to beyond 09N140W. Scattered moderate to locally strong convection is occurring from 09N to 11N between 113W and 117W, and from 08N to 10N between 125W and 132W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Strong to near gale-force N winds are occurring in the Gulf of Tehuantepec as high pressure prevails over central Mexico. Elsewhere, ridging dominates the remainder of the Mexico offshore waters, with gentle to moderate winds and seas of 4 to 6 ft observed. Seas of 1 to 3 ft are occurring in central and northern portions of the Gulf of California. For the forecast, fresh to strong N winds will pulse in the Gulf of Tehuantepec today, and rough to very rough seas will accompany the winds. Conditions will improve by Thu. The tightening pressure gradient between building high pressure offshore of Baja California and upper-level low pressure moving through the southwestern United States will support moderate to locally fresh NW winds north of Cabo San Lazaro tonight into Thu, and fresh to locally strong NW winds in the Gulf of California Thu into this weekend. Looking ahead, strong N winds look to redevelop in the Gulf of Tehuantepec again on Fri, with winds reaching gale-force Fri night through Sat. Strong N winds will prevail in the region through early next week. ...OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Moderate to locally fresh S to SW winds and seas of 6 to 8 ft in cross equatorial SW swell prevail from 01N to 06N east of 90W. Fresh NE winds are pulsing in the Gulf of Papagayo. Otherwise, gentle to locally moderate winds and seas of 4 to 6 ft prevail across the remainder of the offshore waters. For the forecast, moderate NE winds will continue to pulse in the Gulf of Papagayo into Thu. More persistent winds will develop in this region this weekend, with moderate to fresh NE winds expected. NE swell generated by strong offshore winds in the Gulf of Tehuantepec will promote locally rough seas offshore of Guatemala through tonight. Cross equatorial SW swell leading to locally rough seas offshore of Colombia and Panama will subside by early Thu. Elsewhere, light to gentle winds will prevail north of the monsoon trough, with gentle to moderate S to SW winds occurring south of the trough. ...REMAINDER OF THE AREA... A 1021 mb high is centered near 30N122W, and ridging extends across the waters north of the ITCZ, promoting gentle to locally moderate winds north of 16N. Moderate SW winds are occurring north of 25N and west of 135W ahead of low pressure passing north of 30N. Elsewhere, fresh NE winds are noted near a trough analyzed from 08N130W to 15N128W, with moderate to locally fresh NE winds occurring south of 16N and west of 115W. Seas are 6 to 8 ft in this region. South of the ITCZ, moderate SE winds and moderate seas prevail, though localized seas to 8 ft are noted near the ITCZ. For the forecast, low pressure centered near 31N142W will move slowly eastward through Fri before lifting northward. This will support moderate to locally fresh S to SW winds ahead of this system, mainly north of 25N between 128W and 140W, through Fri. Elsewhere, moderate to locally fresh trade winds will prevail west of 110W into early next week. Looking ahead, a long-period NW swell will promote rough seas north of 10N and west of 130W this weekend into early next week. $$ ADAMS
