000 AXPZ20 KNHC 041608 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 1605 UTC Sat Jul 4 2020 Tropical Weather Discussion for the eastern Pacific Ocean from the Equator to 32N, east of 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 1500 UTC. ...TROPICAL WAVES... A tropical wave is analyzed along 85W north of 03N into Central America, moving west at 10 to 15 kt. A few showers are noted from 05N to 10N between 85W and 90W. A tropical wave is analyzed along 98W north of 02N into southern Mexico, moving west at 10 to 15 kt. Scattered moderate convection is occurring from 05N to 10N between 95W and 100W. A tropical wave is analyzed along 109W south of 18N, moving west at 15 kt. Scattered moderate convection is noted from 05N to 10N between 105W and 110W. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from 08N78W to 09N85W to 1011 mb low pressure near 10N95W to 14N105W to 1011 mb low pressure near 14N115W to 1011 mb low pressure near 11N123W to 1011 mb low pressure near 10N138W to beyond 140W. Scattered moderate to strong convection is noted north of 03N and east of 82W. Scattered moderate convection is noted from 05N to 10N between 95W and 100W. Scattered moderate to isolated strong convection is noted from 06N to 14N between 115W and 125W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... A very recent scatterometer satellite pass indicated gap winds a little over 20 kt through the Gulf of Tehuantepec. These winds are squeezed between high pressure over the Gulf of Mexico and a pair of tropical waves passing westward to the south of the region. These winds will diminish later today. A ridge extends from 1026 mb high pressure near 3N137W to south of Cabo San Lucas. This is maintaining generally moderate flow across the waters off Baja California. Northerly swell is forecast to reach the waters north of Punta Eugenia, and increase seas W of northern Baja California early next week. A meandering surface trough is across the Gulf of California. Gentle southerly winds will prevail over the Gulf of California this weekend, then increase to 15-20 kt in the northern Gulf early next week as the pressure gradient tightens in NW Mexico. A broad area of low pressure located several hundred miles south- southwest of Manzanillo Mexico continues to produce disorganized showers and thunderstorms. Some slow development of this system is possible through early next week as it moves west-northwest, well south of southern Mexico. This system has a low chance of tropical cyclone formation. A second low pressure area is forecast to form south of southern Mexico in a couple of days. Environmental conditions are expected to be conducive for development, and a tropical depression could form by the middle of next week as it moves west-northwestward, well south of the coast of southern Mexico. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Moderate to occasionally fresh SW to W winds will prevail over the waters S of 10N this weekend. Long period SW swell will gradually subside across the region through Mon. An area of low pressure is forecast to form west of Central America in a couple of days. Environmental conditions are expected to be conducive for gradual development. REMAINDER OF THE AREA... A ridge will dominate northern forecast waters the next several days. The gradient betA ridge dominates the offshore waters west of Baja California, producing gentle to moderate NW to N winds. Light westerly winds prevail across the Gulf of California. A ridge will dominate the waters west of Baja California this weekend, producing gentle to moderate NW to N winds.ween the ridge and lower pressures near the monsoon trough will support moderate to fresh trade winds across tropical waters, roughly from 10N to 20N west of 120W. Long period cross-equatorial S to SW swell across most of the tropical east Pacific Ocean will gradually subside the next couple of days, with sea heights expected to be 5 to 7 ft. $$ Christensen
