000 AXPZ20 KNHC 010239 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. This trough will move westward over the next couple of days. 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 a moderate to fresh breeze across the waters W of Baja California. A brief pulse of strong N gap winds should occur over the Gulf of Tehuantepec Wed morning. Otherwise tranquil winds will prevail over the Mexican offshore waters through at least Sun night. A long period NW swell will impact the waters west of Baja California Wed through Fri night. Seas will peak near 10 ft N of Punta Eugenia Wed night to Thu night. Seas in the 6 to 9 ft range will dominate most of the offshore forecast waters of Baja California on Fri. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Weak surface ridging over W Caribbean should produce moderate to fresh NE-E winds across the Papagayo region during the overnight and early morning hours. Elsewhere, light to gentle winds and seas in the 3 to 5 ft range are forecast through the next several days. On Sun, the W Caribbean ridge is anticipated to rebuild and force again 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 continues to dominate the northern forecast waters. A moderate N-S pressure gradient between the ridge and lower pressure along the ITCZ is causing fresh to strong NE trades, mainly 08N to 12N W of 134W. Peak seas are around 11 ft in the area of strongest winds. The pressure gradient will relax tonight, and the trades will drop to moderate to fresh conditions through Thu. As the high pressure rebuilds on Fri, expect NE trades to again reach strong breeze conditions. 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
