000 AXPZ20 KNHC 241500 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 1605 UTC Sun Nov 24 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. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from 09N83W to 08N90W to 10N129W. The ITCZ continues from 10N129W to beyond 09N140W. Scattered moderate convection is noted from 07N to 10N between 96W and 122W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... A 1021 mb high pressure is centered over southern Mexico near 18N97W. The pressure gradient between this area of high pressure and lower pressure within the EPAC monsoon trough is supporting fresh to strong winds in the Gulf of Tehuantepec this morning. Elsewhere, a 1019 mb high pressure is centered near 29N127W. A weak and benign cold front is moving slowly eastward extending across the northern Baja California waters, with little change in winds. A trough of low pressure is across the Gulf of California. The pressure gradient between the area of high pressure and the surface trough is supporting gentle to moderate winds across the waters W of the Baja California peninsula, where seas are in the 5-7 ft range. Light to gentle winds, and seas of 5-6 ft prevail over the remainder of the open waters off Mexico. Light to gentle winds, and seas of 1-3 ft, are over the Gulf of California. For the forecast, strong N winds across the Gulf of Tehuantepec will diminish today. Elsewhere, a weak surface ridge centered W of the area will remain in control of the weather pattern across the regional waters W of 105W through the middle of next week, supporting gentle to locally moderate NW to N winds. Strong to near gale-force N winds will return to Tehuantepec Mon night through Wed morning before diminishing. Moderate S swell will move through the area waters from Cabo Corrientes eastward Mon night through Wed. ...OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Fresh to locally strong winds are noted over and downwind the Gulf of Papagayo, where seas of 6-7 ft are noted. Light to gentle winds, and seas of 5-6 ft, prevail elsewhere N of the monsoon trough. S of the monsoon trough, gentle to moderate winds, and seas of 4-5 ft, prevail. For the forecast, fresh to locally strong NE to E winds are expected across the Papagayo region today, as high pressure persists across the NW Caribbean and northern Central America. Elsewhere, gentle to locally moderate winds will prevail through Wed. Cross equatorial SW swell is expected to move into the regional waters Sun night, increasing seas to 8 ft between Ecuador, Colombia and the Galapagos Islands, and to 7 ft elsewhere, early Mon through Wed. Moderate to fresh S to SW winds will develop between the Galapagos Islands and Colombia the middle of the week. ...REMAINDER OF THE AREA... A 1019 mb high pressure is centered near 29N127W. A weak and benign cold front is moving slowly eastward extending across the northern Baja California waters to the waters S of the high center. A second cold front is over the far NW waters. The pressure gradient between the area of high pressure and the second cold front is supporting moderate to fresh winds E of the front. NW swell behind the front is producing seas of 8-9 ft over the far NW waters. The pressure gradient between the area of high pressure and lower pressure within the monsoon trough and in the vicinity of the ITCZ is supporting moderate trades, and seas of 6-8 ft, from 10N to 20N and W of 110W. Moderate to fresh winds, and seas of 6-8 ft are south of the monsoon trough/ITCZ. For the forecast, the high pressure center will drift NE through Mon then become stationary, as the weak front dissipates today. The second front across the NW waters along 30N will meander W of 130W for the next few days, while low pressure forms along the front just NW of the area waters. This will maintain moderate to fresh SW winds and seas around 8 ft across these NW waters through late Tue. To the south, moderate to locally fresh trade winds will continue south of 18N, with moderate seas through Thu. Cross equatorial S to SW swell will move north of the equator Sun night and raise seas to 7 to 9 ft across the waters S of 18N and E of 125W Mon through early Wed. $$ AL
