000 AXPZ20 KNHC 132041 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 2205 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 1800 UTC surface analysis and satellite imagery through 2040 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... A surface trough extends from 07N77W to 05.5N90W. The ITCZ continues from 05.5N90W to 06N117W to 03N122W to beyond 03N140W. Scattered moderate isolated strong convection is noted from 03N to 07N between 84W and 90W, from 03N to 08N between 94W and 100W, from 03N to 07N between 118W and 122W, and from 03N to 08N 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 winds west of the Baja California peninsula. Gentle to moderate westerly winds prevail elsewhere across the open offshore waters, with light to gentle northerly winds over the Gulf of California. Seas are in the 7-9 ft range west of Baja California Norte, 6-8 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 9 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 4-6 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. 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 20N between 118W and 130W. Seas are in the 7-8 ft range elsewhere N of 20N. Seas in the 5-7 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
