000 AXPZ20 KNHC 301558 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 1534 UTC Mon Mar 30 2020 Tropical Weather Discussion for the eastern Pacific Ocean from the Equator to 32N, east of 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 1530 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... During March and April of each year, a double ITCZ is usually present in the southern Hemisphere of the eastern Pacific region. Based on this weather pattern, no monsoon trough is currently present E of 140W. Only weak troughs are analyzed from 07N77W to 03N79W and from 07N86W to 04N94W. The ITCZ, in the northern Hemisphere, continues from 04N94W to beyond 03N140W. A second ITCZ is noted S of the Equator. Scattered moderate convection is occurring from 04N to 06N between 128W and 135W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... The pressure gradient between a ridge over the offshore waters and a trough over N central Mexico will support fresh to strong NW to N winds west of Baja California through tonight. Seas will reach up to 8 ft. Fresh to locally strong NW winds are also expected across the central Gulf of California this evening through early Tue morning. Seas will reach up to 6 ft. A brief pulse of fresh to strong N winds is expected across the Gulf of Tehuantepec this morning. Seas are up to 6 ft. Elsewhere winds will be quiescent through at least Fri night. A long period NW swell will impact the waters west of Baja California Wed through Fri night. Seas will peak near 10 ft Wed night to Thu night. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... A N-S pressure gradient over Central America will produce fresh to strong NE to E gap winds in the Gulf of Papagayo region tonight into Tue morning. Peak seas of up to 8 ft are expected. Quiescent winds and seas are expected elsewhere across the offshore waters through at least Fri night. REMAINDER OF THE AREA... A ridge extends from 30N135W to 15N110W. The pressure gradient between the ridge and lower pressures in the vicinity of the ITCZ is supporting a large area of fresh to strong NE to E trades, primarily west of 125W from 08N to 18N. Overnight altimeter satellite data showed seas of 8 to 12 ft in the area of fresh to strong winds. These are primarily shorter period waves related to the trade wind flow, but also with a component of longer period S swell. Farther east, winds and seas are quiescent over the tropical east Pacific. The trades should diminish by late Tue as the high pressure weakens. As the high rebuilds on Fri, expect NE trades to again reach strong breeze conditions. No significant S hemisphere long-period swell is expected for the next several days. $$ Landsea
