000 AXPZ20 KNHC 230928 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 1005 UTC Sat Apr 23 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 0600 UTC surface analysis and satellite imagery through 0915 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... A surface trough extends from A 1011 mb low that is located in the far southwestern Caribbean near 10N81W southwestward to 07N83W. It continues to 09N109W and to 08N114W, where overnight scatterometer data indicates that it transitions to the ITCZ. The ITCZ extends to 06N122W to 04N130W and to beyond the area at 04N140W. Scattered moderate to isolated strong convection is within 120 nm S of the ITCZ between 115W-117W and within 60 nm S of the ITCZ between 117W-120W. Scattered moderate convection is noted within 60 nm S of the trough between 89W-90W, within 30 nm N of the ITCZ between 122W-127W, and also between 130W-132W and within 30 nm south of the ITCZ between 133W-137W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO A ridge maintains control of the weather regime of the offshore forecast waters of Baja California. The pressure gradient between the ridge and relatively lower pressures over Mexico is supporting moderate to fresh NW-N winds over the waters west of the Baja California peninsula. Light and variable winds are over the remainder of the offshore waters. Gentle to moderate winds are over the Gulf of California. NW swell over the waters off Baja California Norte is bringing seas to 12 ft north of 29N. Areas of haze are offshore the coast of Mexico south of Cabo Corrientes due to nearby persistent agricultural fires. For the forecast, fresh to locally strong NW to N winds will continue over most of the offshore waters of Baja California through tonight. Long-period NW swell over the waters west of Baja California Norte will bring seas greater than 8 ft to the Revillagigedo Islands by early this evening. Strong north winds are expected in the Gulf of Tehuantepec region Tue night through Wed night. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, and WITHIN 750 NM OF ECUADOR Gentle to moderate SE to S winds prevail over the waters between Ecuador and the Galapagos Islands, with light to gentle winds elsewhere. Seas are 5-7 ft in a S to SW swell, reaching 7 ft between Ecuador and the Galapagos Islands. Haze is possible over the offshore waters of Guatemala and El Salvador due to nearby persistent agricultural fires. For the forecast, the long-period S to SW swell will continue across the region. A new set of southerly swell will build seas slightly over the Central American offshore through tonight. then subside a little beginning on Sun. REMAINDER OF THE AREA High pressure ridging, anchored by a strong high center of 1031 N of the area near 34N136W, continues over the waters N of 20N. The pressure gradient between the area of high pressure and lower pressure in the vicinity of the ITCZ is supporting mainly fresh NE trade winds N of the ITCZ to near 25N and west of about 121W. Gentle to moderate winds remain elsewhere. NW swell is propagating across the discussion waters, with seas greater than 8 ft covering the waters northwest of a line from 30N116W to 24N114W to 05N140W. Seas are peaking to 13 ft N of 27N between 121W- 126W. Seas are 5-7 ft elsewhere. For the forecast, the long-period NW swell will continue to propagate southeastward across the forecast waters through the weekend. Seas greater than 8 ft will cover much of the forecast waters west of 105W by Sun night, then begin to decay on Mon. $$ Aguirre
