149 AXPZ20 KNHC 230235 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 0405 UTC Sat Nov 22 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 0000 UTC surface analysis and satellite imagery through 0200 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from 10N85W to 07N97W to 07N103W. The ITCZ extends from 07N103W to 10N119W to 07N140W. Scattered moderate convection is from 08N to 11N between 118W and 125W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... An area of low pressure is centered just offshore Baja California Norte. Fresh winds prevail west of the low over the Baja California Norte waters. Moderate to fresh gap winds are funneling across the Baja California peninsula into the Gulf of California. Gentle to moderate winds are over the waters off Baja California Sur and offshore SW Mexico to the Revillagigedo Islands. Fresh to strong gap winds are across the Gulf of Tehuantepec. Light to gentle winds are noted elsewhere. NW swell, with seas of 8-11 ft are spreading across the offshore waters of Baja California. Elsewhere, seas are mainly in the 4-6 ft range over the open waters off Mexico. Over the Gulf of California, seas are in the 2-4 ft range. For the forecast, the low will shift eastward and dissipate though Sun. Moderate to fresh winds west of the low will diminish overnight. Large NW swell ushered in by the low is spreading across the Baja California Sur waters. Rough seas with this swell 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 Sun night before diminishing. Gap winds will increase again over the Gulf of Tehuantepec the middle of next week. 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 3-6 ft range. For the forecast, moderate to fresh NE to E winds are expected to pulse over and downstream of the Papagayo region into early next week, except pulsing to strong Sun night. Moderate or lighter winds are forecast elsewhere during the forecast period. ...REMAINDER OF THE AREA... The pressure gradient between a 1025 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 23N116W. 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 Sun before starting to slowly subside early next 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 next week. $$ AL
