000 AXPZ20 KNHC 130252 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 0405 UTC Tue Apr 13 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 0200 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... A surface trough extends from 11N74W to 07.5N88W to 06N89W to 05N94W. The ITCZ continues from 05N94W to 07N112W to 03N133W to beyond 03.5N140W. Scattered moderate isolated strong convection is noted from 03.5N to 06.5N between 82.5W and 95W, and from 03.5N to 08N W of 133W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... A ridge of high pressure extends across the waters west of Baja California, and extends southeast to near the Revillagigedo Islands. The pressure gradient between the ridge and a trough over the Gulf of California is supporting moderate to fresh northwesterly winds off of Baja California Norte, and moderate winds off Baja California Sur. Light to gentle westerly winds prevail elsewhere across the open offshore waters, with gentle to moderate southerly winds over the Gulf of California. Seas are in the 6-10 ft range west of Baja California Norte, 4-6 ft off Baja California Sur, 3-5 ft over the remainder of the open waters off Mexico, and 2-3 ft over the Gulf of California. Moderate to fresh NW winds will prevail west of Baja California Norte through Tue as the ridge persists. NW swell off Baja California Norte, currently peaking near 10 ft, will prevail into Wed, with the highest seas across the outer waters. Gentle to moderate winds are expected elsewhere into Wed. Winds and seas are expected to diminish slightly areawide Wed through Fri as the high pressure weakens. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, and WITHIN 750 NM OF ECUADOR... Light to gentle 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, before moderate offshore gap winds begin across the Papagayo region. Moderate sized SW swell crossing the equator will move through the offshore waters through Thu to raise seas slightly. REMAINDER OF THE AREA... High pressure ridging prevails across the northern waters. The pressure gradient between this area of high pressure and lower pressure in the vicinity of the ITCZ is supporting moderate winds north of the ITCZ and west of 120W. Gentle to moderate winds prevail elsewhere. Seas are in the 8-10 ft range over the waters N of 26N between 118W and 130W. Seas in the 4-6 ft range prevail elsewhere. No significant change is expected the next couple of days. Northerly swell will continue to propagate south of 30N across the waters between 118W and 130W through Wed. $$ Stripling
