000 AXPZ20 KNHC 230351 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 0405 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 0000 UTC surface analysis and satellite imagery through 0345 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... A surface trough extends from central Panamas to 07N90W to 09N105W and to 08N113W, where latest scatterometer data indicates that it transitions to the ITCZ and continues to 07N120W to 04N130W and to beyond the area at 03N140W. Scattered moderate to isolated strong convection is within 180 nm south of the ITCZ between 105W-108W. Scattered moderate convection is noted from 04N to 08N between 101W-105W, also within 60 nm of the ITCZ between 116W-120W, and within 60 nm of the ITCZ between 127W- 134W. 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 tonight into Sat night. Long-period NW swell over the waters west of Baja California Norte will bring seas greater than 8 ft to the Revillagigedo Islands by Sat evening. Strong north winds are expected in the Gulf of Tehuantepec region late Tue and Wed. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, and WITHIN 750 NM OF ECUADOR Gentle to moderate winds prevail over the waters between Ecuador and the Galapagos Islands, with light to gentle winds elsewhere. Seas are 4-6 ft in 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, long-period S to SW swell continues across the region. A new set of southerly swell will build seas slightly over the Central American offshore waters tonight through Sat night. The swell will subside a little beginning on Sun. REMAINDER OF THE AREA High pressure 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 moderate to fresh NE trade winds N of the ITCZ to near 25N and west of 120W. Gentle to moderate winds prevail 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 07N140W, peaking to around 13 ft N of 26N between 121W-133W. Seas are 5-7 ft elsewhere. For the forecast, the long-period NW swell will continue to propagate southeastward across the forecast waters. Seas greater than 8 ft will cover much of the forecast waters west of 105W by Sun night before starting to subside. $$ Aguirre
