--------------------------------------------------------------------------- TROPICAL WEATHER DISCUSSION (EASTERN PACIFIC AREA) MESSAGES T1T2: AX A1A2: PZ Date: 2026-03-05 --------------------------------------------------------------------------- Message File: T_AXPZ20KNHC050126_C_KWBC_20260305012654_16515500-8763-TWDEP.txt ****0000004756**** AXPZ20 KNHC 050126 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 0405 UTC Thu Mar 5 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 0100 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... A surface trough extends from 08.5N83.5W to 01N100W to 03.5N114W. The ITCZ extends from 03.5N114W to 06N123.5W to beyond 02N140W. Scattered moderate convection is noted from 02.5N to 04.5N between 85W and 88.5W, and within 180 nm NW of the ITCZ between 121W and 140W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... High pressure well NW of the area extends a ridge southeastward toward Baja California Sur and the Revillagigedo Islands. The pressure gradient between this ridge and a surface trough over NW Mexico is producing moderate to fresh NW to N winds offshore the Baja California waters, becoming moderate northerly winds from Cabo San Lazaro southward to the Revillagigedo Islands. Seas are generally 4 to 7 ft in NW swell across this area. Light northerly winds prevail across the Gulf of California where seas are slight, except moderate winds in the southern Gulf. Elsewhere to the east, a weak pressure gradient is leading to mainly gentle winds across the waters, except moderate to fresh N winds are developing in the immediate Gulf of Tehuantepec. Mainly moderate seas prevail offshore southern and SW Mexico. For the forecast, high pressure well NW of the area will build modestly over the Baja California waters through early Fri and will tighten the pressure gradient there, bringing fresh to strong NW winds during that time. Associated rough seas in northerly swell will persist off Baja California Norte into the weekend. Weak low pressure is expected to form just offshore Baja California Norte Fri through Sat, then shift slowly eastward into early next week. This will push the strong NW winds offshore and W of 120W, and will relax the pressure gradient over area waters, leading to improving marine conditions through the weekend. Winds across Tehuantepec will pulse tonight to fresh to strong speeds, before winds there become variable through the weekend. ....OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Fresh to strong NE to E gap winds are developing across the Papagayo region, with moderate to fresh N gap winds across the Gulf of Panama. Seas are 5 to 8 ft downwind of Papagayo and 4 to 6 ft downwind of the Gulf of Panama. Elsewhere, winds are light to gentle with slight to moderate seas of 5 ft or less in S-SW swell. For the forecast, pulsing fresh to strong winds are expected in the Papagayo area through the weekend and into early next week as high pressure prevails N of the region. Moderate gap winds across the Gulf of Panama will pulse to locally fresh at night, otherwise mainly light to gentle winds will prevail elsewhere through the weekend. Looking ahead, significant cross-equatorial SW swell is expected to reach the waters offshore Ecuador to the Galapagos Islands by Mon of next week. ...REMAINDER OF THE AREA... 1034 mb high pressure centered NW of the region near 38N140W is dominating much of the waters N of 03N and W of 100W. The gradient between this building ridge and the ITCZ is leading to fresh to strong trades from roughly 06N to 28N between 125W and 140W along with 6 to 9 ft seas per recent altimeter passes, and winds are moderate to fresh elsewehre N of 04N and W of 120W. Elsewhere, winds are moderate or weaker. Seas through the remainder of the open waters are 4 to 7 ft in mixed swell. For the forecast, high pressure will build southward over the area into late week, tightening the pressure gradient and expanding the area of fresh to strong winds N of the ITCZ to the W of 120W. Rough seas are expected to accompany these winds, continuing into the weekend. Gale-force winds are forecast just N of the waters to the E of 130W. Looking ahead, low pressure is forecast to develop and linger near Baja California Norte Fri through Sat, then drift slowly eastward into early next week. This is expected to weaken the pressure gradient and gradually improve marine conditions across the waters across regional waters Sat through Mon. $$ Lewitsky ########################### END OF MESSAGE SET ############################ --------------------------------------------------------------------------- Message File: T_AXPZ20KNHC050127CCA_C_KWBC_20260305012754_16515500-8764-TWDEP.txt ****0000004760**** AXPZ20 KNHC 050127 CCA TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 0405 UTC Thu Mar 5 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.
