000 AXPZ20 KNHC 010206 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 146 UTC Wed Apr 1 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 0000 UTC surface analysis and satellite imagery through 0300 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 analyzed from 09N75W to 05N94W. The ITCZ, in the northern Hemisphere, continues from 05N94W to 05N122W, where it is broken by a trough along 124W, then begins again at 04N127W to beyond 02N140W. Scattered moderate isolated strong convection is noted where the trough meets the ITCZ, from 03N to 05N between 122W and 128W. Similar convection is also seen from 04N to 07N between 118W and 122W. 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. $$ GR
