000 AXPZ20 KNHC 140318 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 0405 UTC Wed Apr 14 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 0240 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... A surface trough extends from 10N74W to 07N77W to 05.5N90W. The ITCZ continues from 05.5N90W to 05N117W to beyond 03.5N140W. Scattered moderate isolated strong convection is noted from 04N to 10N between 81W and 108W. Scattered moderate convection is noted from 03.5N to 08.5N between 112W and 140W. 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, locally fresh winds along the coast this evening. Gentle to moderate westerly winds prevail elsewhere across the open offshore waters. Moderate to fresh southerly winds prevail across the far northern Gulf of California, while light to gentle winds prevail across the remainder of the Gulf. Seas are in the 6-9 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 2-4 ft over the Gulf of California. Moderate NW winds will prevail west of Baja California Norte through the week as the ridge persists. NW swell off Baja California Norte, currently peaking around 10 ft, will prevail into Thu, 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 entering the regional waters today will dominate 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 118W. Gentle to moderate winds prevail elsewhere. Seas are in the 8-9 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. $$ Stripling
