000 AXPZ20 KNHC 041546 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 1605 UTC Sat Jun 4 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 1550 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from 13N89W and continues along 11N114W to 06N128W. The ITCZ begins near 06N128W and continues to 06N137W. Isolated moderate convection is from 08N to 14N E of 109W. Scattered moderate convection is from 05N to 12N between 115W and 127W and from 04N to 13N W of 132W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... The pressure gradient between a subtropical ridge located west of the Baja California peninsula and climatologically lower pressures over Mexico continue to support moderate to fresh NW winds north of Punta Eugenia while gentle to locally moderate NW breezes are found elsewhere offshore the peninsula. NW swell is producing seas of 6-8 ft offshore Baja California Norte and 5-6 ft elsewhere to Los Cabos as indicated by recent altimeter data. Gentle to moderate SE winds are along the Gulf of California with seas to 3 ft. Light to gentle variable winds with seas in the 4-6 ft range dominate the remainder Mexican offshore waters, except for the Gulf of Tehuantepec, where locally moderate N winds are present. For the forecast, building high pressure west of the area will support moderate to fresh NW to N winds off Baja California north of Cabo San Lazaro that will persist through early next week. The NW swell will produce 6-8 ft seas into early next week north of Punta Eugenia. Light to locally moderate winds will persist in the remainder of the Mexican waters. ...OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, and WITHIN 750 NM OF ECUADOR... A recent scatterometer satellite pass indicate that the winds south of the W-SW monsoon flow have diminished to mainly moderate. Light to locally moderate SW winds prevail across the Central American and Colombia offshore waters. Seas of 5-8 ft are noted in the offshore waters of northern Central America, while 2-5 ft are found in the offshore waters from Costa Rica to Colombia. Between the Galapagos islands and Ecuador, light to locally moderate southerly flow and seas of 3-5 ft are prevalent. For the forecast, the SW swell to 8 ft off El Salvador and Nicaragua will diminish this afternoon. Looking ahead, another round of SW swell to 8 ft will return to the waters off Guatemala and El Salvador by Mon night. Elsewhere gentle to moderate SW to S winds will persist through early next week. ...REMAINDER OF THE AREA... The 1021 mb subtropical ridge positioned near 28N131W supports fairly tranquil weather conditions across the remainder of the tropical eastern Pacific, outside of the deep tropics. Latest satellite- derived wind data depict gentle to moderate anticyclonic winds north of the monsoon trough and ITCZ. Gentle to moderate southerly winds are also noted south of these troughs. Seas are 5-8 ft, with the highest seas occurring near 10N93W. For the forecast, east of 110W winds and seas will diminish from 05N to the monsoon trough along roughly 10N through Sat night. Looking ahead, SW winds will surge again in this area Sun through early next week, with seas building again to 8 ft in SW swell. Farther west, the subtropical ridge will build by late Sun, allowing trade winds to increase slightly farther south into the tropics. $$ Ramos
