000 AXPZ20 KNHC 130907 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 1005 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 0600 UTC surface analysis and satellite imagery through 0845 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... A surface trough extends from 11N74W to 07N78W to 05N91W. The ITCZ continues from 05N91W to 05N116W to 03N128W to beyond 04N140W. Scattered moderate isolated strong convection is noted from 03.5N to 06.5N between 84W and 123W. Scattered strong convection is noted from 03.5N to 06N W of 135W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... A ridge of high pressure extends southward across the waters west of Baja California, then southeastward 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 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 reached the Galapagos Islands overnight and will move through the offshore waters through Fri 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 to 25N and west of 120W. Gentle to moderate winds prevail elsewhere. Seas are in the 8-10 ft range over the waters N of 22N between 118W and 132W. 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 and act to 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
