000 AXPZ20 KNHC 131510 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 1605 UTC Wed Apr 13 2022 Tropical Weather Discussion for the eastern Pacific Ocean from 03.4S to 30N, east of 120W including the Gulf of California, and from the Equator to 30N, between 120W and 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 the border of Colombia and Panama near 07N77W to 06N85W to 07N105W to 07N118W. The ITCZ extends from 07N118W to 09N126W, then resumes west of a surface trough from 08N132W to 07N137W. Scattered moderate and isolated strong convection is noted from 02N to 08N between 78W and 89W, from 03N to 08N between 94W and 118W, from 08N to 15N between 108W and 116W, from 04N to 10N between 120W and 127W, and from 10N to 16N between 125W and 131W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO The pressure gradient between high pressure north of the area and lower pressure over the western U.S. is supporting fresh to strong NW winds off Baja California Norte with moderate to fresh winds off Baja California Sur. Moderate winds are noted in the central and southern Gulf of California, with light to gentle winds in the northern Gulf of California. Gentle to moderate winds are elsewhere offshore the open waters off Mexico. Seas are in the 10 to 12 ft range offshore Baja California Norte, and 7 to 9 ft off Baja California Sur. Seas of 5 to 7 ft are elsewhere offshore Mexico, and 1 to 3 ft over the Gulf of California, except 2 to 4 ft in the central Gulf of California. Patchy to areas of haze are possible near the coast of southwestern Mexico due to nearby agricultural fires. For the forecast, fresh to strong winds will prevail offshore of Baja California Norte through the remainder of the morning. Northerly swell west of the Baja California peninsula will gradually subside through the remainder of the week. Moderate winds will prevail off Cabo Corrientes into early Fri, then pulse to fresh to strong Sat night. A tight pressure gradient will develop offshore of Baja California Norte Sat. Winds over this area will strenghten, and seas will build to 8 ft, through the remainder of the upcoming weekend. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, and WITHIN 750 NM OF ECUADOR Fresh to strong winds are noted over the Gulf of Papagayo region. Moderate winds are over and downstream the Gulf of Panama, as well as between Ecuador and the Galapagos Islands. Light to gentle winds prevail elsewhere. Seas are in the 4 to 6 ft range, reaching 7 ft over the Papagayo region as well as the waters between Ecuador and the Galapagos Islands. For the forecast, high pressure north of the area will support pulses of fresh to strong winds into the Papagayo region this morning. Moderate winds in the Gulf of Panama will gradually diminish to gentle by the end of the week, then will increase to moderate this weekend. Gentle to moderate S winds will prevail between Ecuador and the Galapagos Islands. Mainly light to gentle winds are expected elsewhere. Moderate S to SW swell offshore of Ecuador to the Galapagos Islands will subside through the end of the week. REMAINDER OF THE AREA High pressure prevails north of the area. The pressure gradient between this area of high pressure and lower pressure in the vicinity of the ITCZ is supporting mainly moderate to fresh anticyclonic flow north of the ITCZ and west of 115W. Seas within this area are in the 7 to 10 ft range. Winds are gentle to moderate elsewhere, except fresh to strong north of 25N and east of 124W, where seas are 8 to 12 ft in fresh northerly swell. Long period southerly swell is affecting the area mainly south of the equator, with seas to 7 ft between 90W and 106W. For the forecast, conditions are expected to gradually improve, with the majority of 8 ft seas expected to subside by Thu, and fresh winds diminishing by Fri. Fairly tranquil marine conditions will then prevail for the end of the week. $$ Lewitsky
