000 AXPZ20 KNHC 091517 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 1605 UTC Fri Apr 9 2021 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... A surface trough extends from 09N80W to 07N87W to 07N102W. The ITCZ continues from 07N103W to 06N124W to beyond 04N140W. Scattered moderate to strong convection is noted from 04N to 08N between 80W and 107W. Scattered moderate to isolated strong convection is noted from 04N to 07N between 120W and 133W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... A ridge of high pressure prevails west of the Baja California, and extends southeast to well offshore of Cabo Corrientes. The pressure gradient between the ridge and a trough over Mexico is supporting fresh to locally strong northerly winds off of Baja California Norte and gentle to moderate winds off Baja California Sur. Light to gentle westerly winds prevail elsewhere across the offshore waters. Seas are in the 5-7 ft range west of Baja California, 3-5 ft over the remainder of the open waters off Mexico, and 1-3 ft over the Gulf of California. Fresh to strong NW winds will prevail west of Baja California Norte through Sun as the ridge persists. NW swell will increase seas off Baja California Norte through Tue, peaking at 7-10 ft Sat night. Gentle to moderate winds are expected elsewhere through Tue. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, and WITHIN 750 NM OF ECUADOR... Light to gentle mostly onshore winds prevail across the forecast area. Seas are in the 3-5 ft range. Little change in wind and wave conditions are expected through Tue. However, numerous showers and thunderstorms are expected to continue N of 04N and E of 95W through tonight. REMAINDER OF THE AREA... Deep layered low pressure west of the area is accompanied by a 1016 mb surface low near 31N144W. A surface trough east of this feature extends into the discussion area, passing just east of 30N140W. Scattered moderate convection is seen along and west of this trough N of 25N and W of 133W. High pressure prevails across the northern waters east of this trough. There is a modest pressure gradient over the forecast waters south of the ridge. Moderate to locally fresh winds prevail north of the ITCZ to near 15N and west of 118W. Seas over this area are in the 6-8 ft range. Gentle to moderate winds and seas in the 4-5 ft range prevail north of 20N. Light to gentle winds and seas of 4-6 ft prevail elsewhere. Little significant change is expected the next couple of days. A weak pressure gradient will continue through Sat with gentle to moderate trade winds expected. High pressure will build modestly over the northern waters Sat through Mon, and slightly strengthen trade winds north of the ITCZ. Northerly swell will propagate south of 30N east of 125W by tonight. Seas over this area will build to around 9-11 ft Sat night and Sun. $$ KONARIK
