Tropical Weather Discussion

Full Alert Message

Tropical Weather Discussion NWS National Hurricane Center Miami FL 0405 UTC Mon Mar 2 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 0200 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... A surface trough is analyzed from 07N81W to 02N96W. The ITCZ extends from 04S100W to beyond 02S120W. Scattered moderate convection is noted S of 00N between 84W and 90W and S of 00N between 110W and 123W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Strong winds and seas of 6 to 8 ft prevail over the Gulf of Tehuantepec. Elsewhere, a weak pressure gradient is resulting in moderate or weaker winds. Moderate seas prevail over the open waters off Mexico, with slight seas over the Gulf of California. For the forecast, high pressure will build toward the area from the NW early this week. This will tighten the pressure gradient offshore Baja California, increasing winds over these waters. Locally strong NW winds are likely Mon and Mon night N of Cabo San Lazaro. The pressure gradient between high pressure over NE Mexico and the equatorial trough will support moderate to fresh winds over the Gulf of Tehuantepec through midweek. Winds will pulse to strong each night with the added component of nocturnal drainage flow. High pressure will build over the waters N of Punta Eugenia by the middle of next w5-7eek. This will further tighten the pressure gradient to support fresh to strong NW winds and building seas. ....OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Fresh winds are over and downstream the Gulf of Papagayo as well as the Gulf of Panama, with seas of 5 to 7 ft. Elsewhere, winds are mainly light to gentle with slight to moderate seas. For the forecast, pulsing fresh to strong winds are expected in the Papagayo area through through the week. Winds will increase to 30 kt tonight into Mon with seas building to 8 to 9 ft downwind of the Papagayo region to near 90W. Fresh to locally strong N gap winds and moderate seas will pulse in the Gulf of Panama and just S of the Azuero Peninsula. ...REMAINDER OF THE AREA... High pressure prevails over the waters N of 20N. There is a weak pressure gradient between this area of high pressure and lower pressure in the vicinity of the ITCZ. This is resulting in winds moderate or weaker over the discussion waters. Seas are in the 4-7 ft range. For the forecast, little change in marine conditions is expected into mid week. High pressure will build over the area by Wed and Thu, tightening the pressure gradient. With the tightening pressure gradient, areas of locally strong winds and rough seas are possible N of 15N for the latter half of the week.
