000 AXPZ20 KNHC 312154 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 2126 UTC Tue Mar 31 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 1800 UTC surface analysis and satellite imagery through 2130 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... Climatological pattern of the ITCZ during the months of March and April typically exhibits dual axes, one north of the Equator and the other one to the south of the Equator as presently observed. Based on this weather pattern, no monsoon trough is currently present E of 140W. A weak trough is present from 07N78W to 05N94W. The ITCZ, in the northern Hemisphere, extends from 05N94W to 05N121W, where it is broken by a trough along 123W, then begins again at 04N126W to beyond 01N140W. Scattered moderate isolated strong convection is occurring from 02N to 07N between 132W and 120W. Scattered moderate convection is located from 05N to 08N between 83W and 87W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... The weak pressure gradient between a ridge over the offshore waters of Baja California and lower pressure over NW Mexico is producing only moderate to fresh breeze conditions across the Mexican offshore waters. A brief pulse of strong N gap winds should occur over the Gulf of Tehuantepec tomorrow morning. Otherwise tranquil winds will prevail over the Mexican offshore waters through at least Sun night. A mix of long period NW and S swell will impact the waters west of Baja California tomorrow through Fri night. Peak seas will reach to around 10 ft Wed night through Thu night. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Weak surface ridging over W Caribbean should produce quiescent conditions across the Central American and equatorial offshore waters during the next several days. On Sun, the W Caribbean ridge is anticipated to rebuild and force fresh to strong NE to E gap winds in the Gulf of Papagayo region. Peak seas there on Sun may reach up to 8 ft. No significant long-period swell should affect the waters through at least Sun night. REMAINDER OF THE AREA... A surface ridge extends from a 1031 mb high near 37N141W southeastward to 30N125W to 20N110W to 13N90W. A moderate N-S pressure gradient between the ridge and lower pressure along the ITCZ is causing fresh to strong NE trades, mainly from 08N to 16N west of 130W. Peak seas are around 11 ft in the area of strongest winds. The gradient will relax this evening and the trades will drop to moderate to fresh conditions through Thu. From Thu night to early Sat, the ridge rebuilds and the trades restrengthen. A mix of long period NW and S swell will impact the waters west of Baja California tomorrow through Fri night. Peak seas will reach to around 10 ft tomorrow night through Thu night. On Sat, a large SW swell event should begin impacting the waters near the equator between 100W and 130W. Peak seas on Sat should be near 8 ft. $$ Landsea
