000 AXPZ20 KNHC 300243 RRA TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 114 UTC Mon Mar 30 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... A surface trough extends from 08N84W to 07N95W. The ITCZ continues from 07N95W to 06N120W to beyond 04N140W. No significant convection is noted at this time. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... A surface ridge extends from the north-central Pacific toward the offshore forecast waters of Baja California. The pressure gradient between the ridge and low pressure over central Mexico supports an area of fresh to strong NW-N winds N of 26N E of 117W. These winds are expected to persist through tonight with seas building to 8 ft. In addition, fresh to locally strong NW winds are expected across the central Gulf of California this evening through early Tue morning. The high pressure will weaken through mid-week allowing for winds off Baja California to diminish. Gentle west to northwest winds will dominate the waters between Cabo Corrientes and the Tehuantepec region through the period, except for a brief pulse of fresh to strong northerly winds across the Gulf of Tehunatepec early this morning. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... High pressure north of the western Caribbean will maintain fresh to strong NE-E winds in the Gulf of Papagayo region this morning, with seas building to 8 ft. Similar marine conditions are expected tonight into Tue morning. Fresh northerly winds across the Gulf of Panama will continue through this morning. Light to gentle winds are expected elsewhere across the offshore waters through the middle of the week. REMAINDER OF THE AREA... A ridge dominates the northern forecast waters. This is supporting a large area of fresh to strong trade winds from 09N to 22N W of 130W, and from 08N to 16N between 120W and 130W based on the most recent scatterometer data. Altimeter satellite data showed seas of 8 to 12 ft in the area of fresh to strong winds. These are primarily shorter period wave related to the trade wind flow, but also with components of longer period northerly swell. Farther east, light to moderate winds and 4 to 6 ft seas are noted over the tropical east Pacific. A surface trough persists along 135W near the ITCZ. Scattered showers and isolated thunderstorms are ongoing near this trough. The ridge will weaken into the middle part of the week, allowing for winds to diminish and wave heights to subside west of 120W. $$ GR
