****0000006694**** AXPZ20 KNHC 011546 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 1605 UTC Sat Feb 1 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 1200 UTC surface analysis and satellite imagery through 1500 UTC. ...SPECIAL FEATURES... Gulf of Tehuantepec Gale Warning: Gale conditions are currently ongoing in the Tehuantepec region and downwind to about 14.5N with fresh to strong northerly winds extending farther south to near 12N. Seas are expected to build to 12 ft with the strongest winds. Gale force winds and rough seas are expected to persist through early Sun morning before diminishing below gale force. Fresh to strong winds will then continue through Mon night, then will pulse to strong again Tue night. Please read the latest NWS High Seas Forecast issued by the National Hurricane Center at website https://www.nhc.noaa.gov/text/MIAHSFEP2.shtml for further details. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from 1007 mb low pressure located over northwestern Colombia near 10N75W to 09N87W to 06N98W. The ITCZ continues from 06N98W to 07N110W to 06N130W to beyond 07N140W. Scattered moderate to isolated strong convection is noted from 04N to 07N east of 81W to the coast of Colombia, and from 05N to 10N west of 121W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... A Gale Warning remains in effect for the Gulf of Tehuantepec. Please, refer to the Special Features section for more details. A broad ridge, centered on a 1026 mb high pressure located near 30N126W, extends southeastward to offshore of Cabo Corrientes, Mexico and dominates the Baja California offshore waters. This ridge supports moderate to locally fresh NW to N winds west of the Baja California Peninsula, with winds then becoming northerly and extending southward to the Revillagigedo Islands. Moderate to fresh NW to N winds are noted over the central and southern parts of the Gulf of California, extending southward to along the coast near Cabo Corrientes. Seas are 5 to 7 ft across the central Gulf of California to offshore of Cabo Corrientes, as measured by recent satellite altimeter data, 4 to 6 ft in NW swell across the offshore waters of Baja California, and 3 ft or less seas in the northern Gulf of California. For the forecast, aside from the Gulf of Tehuantepec gale-force gap wind event discussed above, the current ridge centered west of Baja California will generally remain in place, and slowly weaken through the weekend, before shifting SW and weakening further Sun night through early next week. This pattern will produce moderate to locally fresh NW to N winds and moderate seas across the Baja offshore waters today before winds diminish modestly over the reminder of weekend. As this occurs, seas will subside very slightly through Mon. In the central and southern Gulf of California, winds will gradually become moderate to fresh NW to N winds with moderate seas today, then diminish more significantly Sun. Winds will be moderate or weaker with mainly moderate seas elsewhere through the next several days. Looking ahead, moderate W-NW swell will move through the Baja offshore waters Mon through Tue night. ...OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... A broad ridge extends from the west central Atlantic southwestward across the NW Caribbean into the Yucatan Peninsula. This ridge is producing moderate to fresh NE to E gap winds across the Papagayo region, spreading downstream to about 90W. Seas are 5 to 8 ft there. Farther east, this same high pressure ridge supports gentle to moderate northerly winds across the Gulf of Panama. Seas are 3 to 4 ft downstream of the Azuero Peninsula to beyond 05N. Elsewhere, moderate or weaker winds and slight to moderate seas prevail. For the forecast, high pressure will continue across the western Atlantic to the north of the area and support pulsing fresh to strong NE to E gap winds across the Papagayo region through the middle of next week. Peak seas will build to around 8 ft each late night through morning. Gentle to moderate N winds will prevail in the Gulf of Panama, and are expected to pulse to locally fresh speeds Sun night and Mon night, as strong trades across the south-central Caribbean funnel into the Gulf of Panama. Moderate or weaker winds and slight to moderate seas in SW swell will prevail elsewhere. Seas generated in the gap wind areas of Tehuantepec and Papagayo are forecast to impact the outer offshore waters of Guatemala and El Salvador through Sun evening. ...REMAINDER OF THE AREA... Most of the basin is dominated by a subtropical ridge centered on a 1026 mb high pressure situated near 30N126W, extending southward into the forecast region north of the ITCZ between 110W and 140W. Fresh to locally strong trades are found across the southern periphery of the ridge, covering a large area from 07N to 14N W of 118W. Seas are 8 to 10 ft within this zone of winds. Gentle to moderate anticyclonic flow is noted across most of the waters N of 20N, with the exception of the NW corner of the forecast area where southerly winds are on the increase between the above mentioned ridge and a deepening low pressure system located N of Hawaii. Gentle to moderate winds and moderate seas or less are occurring across the remainder of the open waters, including south of the ITCZ. For the forecast, fresh to locally strong winds and rough seas across the tradewind zone will begin to slowly improve today into early next week as the high pressure center to the north slowly weakens, resulting in a weakening pressure gradient. Deep low pressure north of Hawaii and an associated cold front are forecast to remain W of the forecast area through Mon, and will bring increasing southerly winds and building seas over the NW waters, particularly N of 25N and W of 135W through Sun. Seas will build to 12 to 14 ft NW of a line 30N138W to 28N140W by Sun afternoon. Moderate to large W to NW swell will dominate the waters N of 20N and W of 130W today through the middle of the upcoming week. $$ GR
