574 AXPZ20 KNHC 022122 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 2205 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 1800 UTC surface analysis and satellite imagery through 2100 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... A surface trough is analyzed from 01S81W to 03.4S88W. The ITCZ extends from 03N131W to beyond 03N140W. Scattered moderate convection is noted from 02S to 03.4S between 90W and 96W, and from 01N to 06N between 136W and 140W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Strong winds and seas of 6 to 8 ft prevail over the Gulf of Tehuantepec. High pressure is building SE toward Baja California, causing moderate to fresh NW winds offshore Baja California Norte. Elsewhere, a weak pressure gradient is leading to light to gentle winds. Moderate seas prevail over the open waters off Mexico, with slight seas over the Gulf of California. For the forecast, a tightening pressure gradient offshore Baja California will increase winds to fresh to locally strong through tonight N of Cabo San Lazaro. The pressure gradient between high pressure over NE Mexico and the equatorial trough will support strong gap winds in the Gulf of Tehunatepec tonight and Tue night. High pressure will build over the waters N of Punta Eugenia by mid-week. This will further tighten the pressure gradient to support fresh to strong NW winds and building seas off Baja California. Rough to very rough seas will then persist there through the end of the week and into the weekend. ....OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Strong gap winds are in the Papagayo region per recent ASCAT scatterometer data and a METAR site right on the coast, with similar winds also in the Gulf of Panama, and seas in both areas at 5 to 7 ft. Elsewhere, winds are mainly light to gentle with slight to moderate seas. Scattered moderate convection is noted just SW of the Galapagos Islands. For the forecast, pulsing fresh to strong winds are expected in the Papagayo area through through the week and into the weekend. Winds will increase to 30 kt tonight into Tue morning and Tue night into Wed morning, with seas building to 8 to 9 ft downwind of the Papagayo region to near 90W. Fresh N gap winds and moderate seas will pulse in the Gulf of Panama and just S of the Azuero Peninsula, except fresh to strong through Tue night. ...REMAINDER OF THE AREA... High pressure centered just N of the region is dominating much of the waters N of 10N. This is leading to mainly moderate or weaker NE to E winds N of the Equator along with moderate seas, except to fresh from 05N to 21N and W of 135W with seas to rough there. A surface trough is analyzed from 07N123W to 00N121W with scattered moderate convection noted from 03N to 08N between 118W and 128W. For the forecast, little change in marine conditions is expected into mid-week. High pressure will build over the area Wed and Thu, tightening the pressure gradient. As this occurs, areas of locally strong winds and rough seas are possible over the NW waters roughly N of 05N and W of 115W for the latter half of the week and into the weekend. $$ Lewitsky
