000 AXPZ20 KNHC 131429 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 1605 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 1200 UTC surface analysis and satellite imagery through 1440 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... A surface trough extends from 08N79W to 06N91W. The ITCZ continues from 06N91W to 06N116W to 03N122W to beyond 04N140W. Scattered moderate convection is noted from 03N to 07N between 84W and 99W and from 03N to 06N between 116W and 130W. Scattered moderate isolated strong convection is noted from 04N to 09N W of 135W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... A ridge of high pressure extends across the waters west of Baja California 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, 4-7 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 NW winds will prevail west of Baja California Norte through through the week as the ridge persists. NW swell off Baja California Norte, currently peaking around 10 ft, will prevail into late 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 Thu 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 conditions are expected through into Thu, except for moderate offshore gap winds across the Papagayo region. Moderate sized SW swell has will move through the offshore waters through Fri, raising 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 21N between 118W and 130W. Seas in the 5-6 ft range prevail elsewhere. No significant change is expected the next couple of days. High pressure will sink southward to along 30N late Thu through Fri. This will tighten the pressure gradient and freshen winds north of the ITCZ Fri night into the weekend. Northerly swell will continue to propagate south of 30N across the waters between 118W and 130W through Thu. $$ AL
