000 AXPZ20 KNHC 050249 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 0219 UTC Sun Apr 5 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 0240 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... A trough extends from 07N78W to 03N98W. The ITCZ continues from 03N98W to 01N113W to 02N140W. Widely scattered moderate convection isolated strong convection is noted from 03N to 06N between 83W and 95W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... A surface ridge extends from 1032 mb high pressure near 47N154W to the Revillagigedo Islands. The pressure gradient between this ridge and a surface trough over the Gulf of California is supporting moderate N-NW winds off Baja California. Light S to SW winds persist across most of the Gulf of California, while light to gentle NW to W winds prevail across the remaining Mexican waters from Cabo Corrientes to the Gulf of Tehuantepec. Seas of 5 to 7 ft prevails W of the Baja California peninsula. Farther south, seas of 4 to 6 ft in a mix of NW and SW swell prevails. Low pressure will form north of the area over southern California early next week. An associated cold front will slowly approach Baja California and the Gulf of California through Tue. Fresh to strong SW winds will pulse each night across the northern Gulf of California ahead of the front tonight, Sun night and again Mon night. Otherwise generally quiescent conditions will persist across the offshore waters of Mexico through Tue. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Rather quiet conditions are observed over the Central American and equatorial waters, with light to gentle winds and seas in the 3-5 ft range prevailing. These conditions are expected to change little tonight. Early next week, a western Caribbean high pressure ridge is forecast to build southward. This will tighten the pressure gradient over the region and produce fresh to strong northeast to east gap winds across the Gulf of Papagayo region. Long-period southwest swell will reach the waters between Ecuador and the Galapagos Islands on Sun. REMAINDER OF THE AREA... A ridge extends from high pressure of 1032 mb is centered well northwest of the area near 47N154W to near the Revillagigedo Islands. The pressure gradient between the ridge and lower pressure in the vicinity of the ITCZ is supporting gentle to moderate winds, and seas of 5-7 ft. The area of high pressure over the northern waters has weakened enough to loosen the pressure gradient and diminish winds to the moderate range over the tradewind belt. Associated seas have subsided below 8 ft over the tropical waters. These conditions will prevail through Tue. Fresh trade winds will return late Tue through mid week as high pressure builds in the wake of the front. $$ AL
