000 AXPZ20 KNHC 110311 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 0405 UTC Sun Apr 11 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 0000 UTC surface analysis and satellite imagery through 2320 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... A surface trough extends from 10N74W to 06N95W. The ITCZ continues from 06N96W to 06N113W to 05N140W. Scattered moderate convection is noted from N of 06N between 83W and 88W. Scattered moderate isolated strong convection noted along and within 150 nm N of ITCZ between 102W and 133W. Scattered moderate convection noted N of 29N W of 139W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... A ridge of high pressure prevails west of the Baja California, and extends southeast to offshore of Cabo Corrientes along 110W. The pressure gradient between the ridge and a trough over Mexico is supporting fresh northerly winds off of Baja California to the north of Cabo San Lazaro, and moderate winds off Baja California Sur. Light to gentle westerly winds prevail elsewhere across the offshore waters. Seas are in the 5-9 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 NW winds will prevail west of Baja California Norte into Sun night as the ridge persists, with locally strong winds expected from near Isla Guadalupe northward. Increased NW swell off Baja California Norte will prevail into Tue night, peaking at 8-11 ft tonight. Gentle to moderate winds are expected elsewhere into Tue night. 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, with seas in the 3-5 ft range. Little change in wind and wave conditions are expected into Tue night, before moderate offshore gap winds begin across the Papagayo region. REMAINDER OF THE AREA... A weak surface trough associated with a deep area of low pressure located just W of the NW waters continues nearly N to S along 140W. Fresh SE winds and seas of 7-8 ft prevail across the far NW waters E of the trough and N of 27N. Scattered moderate convection is seen along and east of this trough from 29N to 36N between 138W and 140W. High pressure extends southward across the northern waters between this trough and 110W. This is producing a modest pressure gradient over the forecast waters south of the ridge. Moderate winds prevail north of the ITCZ to near 14N and west of 120W. Seas over this area are in the 5-7 ft range. Moderate winds and seas of 5-8 ft prevail elsewhere west of 120W. Little significant change is expected the next couple of days. High pressure will build over the northern waters through Mon, and slightly strengthen trade winds north of the ITCZ. Northerly swell will propagate south of 30N across the waters east of 125W into the start of next week. Seas over this area will build to around 9-11 ft tonight and Sun. $$ Stripling
