000 AXPZ20 KNHC 021556 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 1605 UTC Fri Feb 2 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 1550 UTC. ...SPECIAL FEATURES... Large NW swell with a period of 10 to 16 seconds is moving across the E Pacific open waters N of 20N, with peak seas to 16 ft per recent altimeter data. Seas greater than 12 ft cover the waters N of 20N and W of 115W. These 12 ft seas will continue to slowly propagate SE while subsiding. By Sat, seas associated with this swell will subside below 12 ft. Also early on Sat, a new cold front will enter the NW waters bringing a new set of NW swell with seas 12 ft or greater over the far NW waters. Seas will peak near 18 ft with this swell on Sat night. The 12 ft seas will spread S and E, covering much of the waters N of 08N and W of 128W by Tue night before starting to subside below 12 ft. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The equatorial trough extends from the coast of Colombia near 06N77W to 03N84W to 05N92W. The ITCZ continues from 05N98W to 06N120W to beyond 03N140W. Numerous moderate isolated strong convection is off the coast of Colombia and Ecuador from 01S to 06N E of 82W. Scattered moderate convection is from 01N to 07N between 82W and 92W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... The remnants of a cold front, analyzed as a surface trough are moving across the central Gulf of California into Baja California Sur, then SW to near 21N121W. Large NW swell, with seas of 8-14 ft follows the trough, affecting the Baja Peninsula offshore waters N of Cabo San Lazaro this morning. The trough also supports fresh to strong W to NW winds over the Gulf of California waters N of 26N, where seas are in the 3-6 ft range. Moderate to fresh NW winds are noted W of the Baja California peninsula, including the entrance of the Gulf of California. Elsewhere, light to gentle winds, and seas of 5-6 ft, prevail in mixed S and NW swell. For the forecast, the surface trough will spread across the remainder Baja California Sur today while weakening. Large NW swell will continue to spread across the waters off the Baja California peninsula and then across the waters off SW Mexico through the weekend. The next gap wind event in the Gulf of Tehuantepec is expected early next week, with gale force winds possible starting Mon night. ...OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Fresh to strong NE to E winds are in the Gulf of Papagayo region, where seas are in the 6-7 ft range. Moderate to fresh winds, and seas of 5-6 ft continue to pulse in the Gulf of Panama, reaching as far as 02N. Over the offshore waters between the coast of Ecuador and the Galapagos Islands, winds are gentle to moderate from the south with 5-6 ft seas in SW swell. Elsewhere, light to gentle winds, and seas of 4-6 ft prevail. For the forecast, strong to near gale-force winds in the Papagayo region are expected to continue through this morning. Moderate to locally fresh winds in the Gulf of Panama will diminish today. Gentle breezes and moderate S to SW swell will prevail elsewhere. ...REMAINDER OF THE AREA... See the Special Features Section for information on an ongoing large swell event. A cold front extends from Baja California Sur SW to near 20N140W. Moderate to fresh winds are noted on either side of the front N of 25N, and westward to near 130W. The front has ushered in a large set of NW swell. Aside from the area of 12 ft seas discussed above, seas greater than 8 ft cover the waters NW of a line from Baja California Norte to near 10N140W. High pressure of 1020 mb is centered N of the front near 26N136W. Light winds are in the vicinity of the high center. The pressure gradient between the 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 15N and W of 130W. Gentle to moderate winds are found elsewhere across the waters, with seas in the 5-7 ft. For the forecast, seas greater than 8 ft will spread SE through the first half of the weekend, covering much of the waters N of 05N and W of 110W by Sat night before subsiding. Low pressure will approach the NW waters Fri, with associated cold front approaching the NW waters Fri evening. Fresh to strong winds are expected ahead and behind the front. The front will usher in another set of large NW swell, as discussed in the SPECIAL FEATURES section above. The area low pressure will strengthen while moving eastward near 31N. This could bring gale force winds into the forecast waters by late Sat afternoon or Sat evening. $$ Ramos
