000 AXPZ20 KNHC 130232 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 0405 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 0000 UTC surface analysis and satellite imagery through 0230 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... A surface trough extends from the border of Colombia and Panama near 07N77W to 05N85W to 07N101W to 07N117W. The ITCZ extends from 07N117W to 09N125W, then resumes west of a surface trough from 08N132W to beyond 06N140W. Scattered moderate and isolated strong convection is noted from 01N to 08N east of 96W, from 04N to 14N between 100W and 112W, and from 04N to 13N between 120W and 140W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO The pressure gradient between high pressure over the eastern Pacific and lower pressure over the western U.S. is supporting fresh to strong NW winds off Baja California Norte with gentle to moderate winds off Baja California Sur. Moderate to fresh winds are just offshore Cabo Corrientes. Gentle to moderate winds are elsewhere offshore the open waters off Mexico. Light to gentle winds prevail over the Gulf of California. Seas are in the 10 to 13 ft range offshore Baja California Norte, and 7 to 9 ft off Baja California Sur. Seas of 5-7 ft are elsewhere offshore Mexico, and 1-3 ft over the Gulf of California. Patchy to areas of haze is 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 early Wed. Large northerly swell north of 29N will persist tonight. Seas to 8 ft will propagate as far south as 21N by Wed before, gradually subsiding through the remainder of the week. Moderate to fresh winds will pulse near Cabo Corrientes into early Wed, and fresh to strong Sat night. A tight pressure gradient will redevelop offshore of Baja California Norte Sat afternoon and night, with winds once again increasing to fresh to strong, and seas building 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 Moderate to fresh winds are noted over the Gulf of Papagayo region. Moderate to locally fresh winds are over and downstream the Gulf of Panama. Light to gentle winds prevail elsewhere. Seas are in the 4-6 ft range, reaching 7 ft over 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 through Wed evening, then again early Fri. Fresh 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 moderate to fresh anticyclonic flow north of the ITCZ and west of 120W. Seas within this area are in the 7 to 10 ft range. Winds are gentle to moderate elsewhere, except fresh to strong north of 26N and east of 125W. Long period swell from the southern hemisphere is affecting the area south of 10N, with seas of 6 to 8 ft, highest south of the equator between 90W and 110W. For the forecast, the northerly swell will gradually subside through the week. A reinforcing set of northerly swell will propagate into the area east of 125W and north of 22N through Wed. Conditions are expected to gradually improve, with the majority of 8 ft seas expected to subside by Thu. Southerly swell affecting areas south of 10N will gradually subside through the week. Fairly tranquil marine conditions will then prevail for the end of the week. $$ AL
