000 AXPZ20 KNHC 311547 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 1514 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 1200 UTC surface analysis and satellite imagery through 1500 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. The ITCZ, in the northern Hemisphere, extends from 06N95W to beyond 02N140W. Scattered moderate isolated strong convection is occurring from 02N to 07N between 132W and 120W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... The pressure gradient between a ridge over the offshore waters of Baja California and a trough over Sonora and Sinaloa is supporting a NW fresh to strong breeze across the central Gulf of California. Seas are peaking now around 6 ft. These winds will diminish this afternoon. A brief pulse of strong N gap winds should occur over the Gulf of Tehuantepec on Wed morning. Seas should reach only to around 6 ft. Otherwise tranquil winds will prevail over the Mexican offshore waters through at least Sat night. A mix of long period NW and S swell will impact the waters west of Baja California Wed 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... A surface ridge over W Caribbean is helping to produce fresh to strong NE to E gap winds in the Gulf of Papagayo region this morning. Peak seas are around 7 ft. Otherwise, quiescent conditions should prevail across the Central American and equatorial offshore waters through at least Sat night. No significant long-period swell should affect the waters also through at least Sat night. REMAINDER OF THE AREA... A surface ridge extends from a 1030 mb high near 35N140W southeastward to 30N125W to 18N110W to 15N95W. 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 125W. Overnight altimeter passes shows peak seas around 12 ft in the area of strongest trades. The gradient will relax this afternoon 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 Wed through Fri night. Peak seas will reach to around 10 ft Wed 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
