802 AXPZ20 KNHC 230833 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 1005 UTC Sun Nov 23 2025 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 09.5N85W to 07N100W. The ITCZ extends from 07N100W to 10N121W to 07N140W. Scattered moderate and isolated strong convection is from 07N to 12N between 120W and 128W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... An area of low pressure is moving across Baja California Norte. Gentle to moderate winds prevail over the waters west of the Baja California peninsula extending southward to the Revillagigedo Islands and southeastward to Cabo Corrientes. Gentle to moderate winds are also over the Gulf of California. Fresh to strong winds are over the Gulf of Tehuantepec. Light to gentle winds prevail elsewhere. Seas are in the 7-11 ft over the waters W of the Baja California peninsula in large NW swell. Seas of 6-8 ft are over the Gulf of Tehuantepec. Elsewhere over the open waters off Mexico, seas are in the 4-6 ft range. Over the Gulf of California, seas of 2-4 ft are noted. For the forecast, the low will dissipate today. Large NW swell ushered in by the low is spreading across the Baja California Sur waters, and will spread southward to the Revillagigedo Islands through Mon before starting to subside. Fresh to strong N gap winds can be expected over the Gulf of Tehuantepec through tonight before diminishing. Gap winds will increase again over the Gulf of Tehuantepec the middle of the week, possible reaching gale force Thu and Thu night. Elsewhere, benign marine conditions are expected. ...OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Moderate to fresh winds are over the Papagayo region, with moderate winds extending downstream of Papagayo to near 92W. Light to gentle winds are elsewhere. Seas are in the 3-5 ft range. For the forecast, moderate to fresh NE to E winds will pulse over and downstream of the Papagayo region this week, except pulsing to strong tonight, Wed night, and Thu night. Moderate or lighter winds are forecast elsewhere during the forecast period. ...REMAINDER OF THE AREA... The pressure gradient between a 1026 mb high pressure centered near 36N136W and lower pressure in the vicinity of the ITCZ is supporting moderate to fresh winds N of the ITCZ to 20N and W of 120W. NW swell is propagating across the discussion waters, with rough seas in excess of 8 ft covering the waters NW of a line from 06N140W to 20N115W. Gentle to moderate winds and seas of 4-7 ft prevail over the remainder of the discussion waters. Rough seas of 8 ft or greater in NW swell will propagate across the area, covering much of the discussion waters N of 08N and W of 110W today before starting to slowly subside early this week. Moderate to fresh trades will continue over the waters N of the ITCZ to near 20N and W of 110W through the middle of the week. $$ AL
