913 AXPZ20 KNHC 060320 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 0405 UTC Tue Jan 6 2026 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 0300 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from 08N78W to 08N84W to 06N95W. The ITCZ continues from 06N95W to 10N125W to beyond 08N140W. Scattered moderate convection is evident from 07N to 10N between 130W and 140W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Weak ridging along roughly 25N is supporting gentle to moderate breezes across the Mexican offshore waters. NW swell to 8 ft over the waters beyond 90 nm off Baja California are subsiding, but just ahead of another round of large NW swell approaching the area ahead the next cold front. For the forecast, the front will dissipate as it moves across Baja California and the Gulf of California through mid week. The large swell will persist off Baja California Norte through Thu, with very large swell possible by Fri as reinforcing swell enters the area. The NW swell will reach Cabo San Lazaro Fri and the Revillagigedo Islands Sat. Meanwhile, high pressure building north of the area over the Great Basin will support fresh to strong NW winds across the Gulf of California Fri and Sat. Farther south, fresh gap winds are possible Wed over the Gulf of Tehuantepec. Looking ahead, gale- force gap winds and rough seas are possible across the Gulf of Tehuantepec Sat as a strong cold front moves through southern Mexico ....OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... High pressure extending into the northwest Caribbean is supporting fresh to strong NE gap winds across the Papagayo region, and moderate to locally fresh northerly gap winds across the Gulf of Panama. Seas downwind of Papagayo are 5 to 7 ft and 4 to 6 ft downwind of the Gulf of Panama. Elsewhere, light to gentle winds prevail north of 05N, with moderate S to SW winds occurring south of 05N. Slight to moderate seas in SW swell continue across these waters. For the forecast, high pressure north of the region will support pulsing fresh to strong winds across the Papagayo region through tonight, with moderate to fresh pulses thereafter through Fri. Pulsing northerly winds are expected across the Gulf of Panama during the next several days. Gentle to moderate breezes and slight to moderate seas will persist elsewhere. ...REMAINDER OF THE AREA... A sharp mid to upper level trough reaching from off northern California to 20N140W is supporting a few showers and thunderstorms from 18N to 21N between 125W and 135W. Moderate to fresh NW to N winds follow a cold front that is moving south of 30N between 130W and 140W. Moderate to fresh NE to E trade winds cover the area north of the ITCZ and west of 115W. Moderate to fresh SE winds are south of the ITCZ and west of 110W. Gentle breezes are noted elsewhere. NW swell of 8 to 11 ft covers the waters north of 05N and west of 115W. Wave heights are 5 to 7 ft elsewhere west of 110W and 4 to 5 ft east of 110W. For the forecast, the cold front will move eastward across the waters north of 22N through mid week, before stalling and dissipating over northwest Mexico late Wed into Thu. High pressure building behind the front will support fresh trade winds and rough seas from 10N to 20N west of 125W. The large swell currently across the regional waters will subside through mid week, just as new NW swell moves into the waters north of 20N through the latter part of the week. Gentle to moderate breezes and moderate seas will persist elsewhere through mid week. $$ Christensen
